I don't think you noticed the sarcasm regarding "luminaught".. As in, not enlightened. And clearly no intellectual argument have you put forth yet. :/
I'm not a religous kind of guy but I think we are a modified creature, not an evolved thing. I don't understand why humans have some DNA which is not shared by any other creature.
Please give an example of a trans species, not just a claim of incrementalism,
unless you can demonstrate this most basic of evidence I'm afraid I'll have to keep thinking Darwin wasn't exactly right, nor are creationists, We are far too mysterious for that.
I do hold a degree in Cultural Anthopology, but I'm not an expert on the way species developed.
Just one cat with wings would work just dandy, or even an ape driving a Mercedes and wearing a Rolex, oh I know, a single celled creature whose turgor pressure endurance has changed, that would be pretty easy, just one cell in all of time.
I do know that DNA is sometimes damaged, but that isn't evolution,
that is a birth defect, which would be selected out.
what is it 223 gene pairs we do not share with any other creature?
Mutants are not evolution, mutants are damaged instruction sets.
BTW please try to give a true example of a trans species fossil, just one okay?
Microevolution is a change in gene frequency within a population over time. This change is due to four different processes: mutation, selection (natural and artificial), gene flow and genetic drift.
Population genetics is the branch of biology that provides the mathematical structure for the study of the process of microevolution. Ecological genetics concerns itself with observing microevolution in the wild. Typically, observable instances of evolution are examples of microevolution; for example, bacterial strains that have antibiotic resistance.
Macroevolution is evolution on a scale of separated gene pools. Macroevolutionary studies focus on change that occurs at or above the level of species, in contrast with microevolution, which refers to smaller evolutionary changes (typically described as changes in allele frequencies) within a species or population.
Speciation is the evolutionary process by which new biological species arise. The biologist Orator F. Cook seems to have been the first to coin the term 'speciation' for the splitting of lineages or 'cladogenesis,' as opposed to 'anagenesis' or 'phyletic evolution' occurring within lineages. Whether genetic drift is a minor or major contributor to speciation is the subject matter of much ongoing discussion.
There are four geographic modes of speciation in nature, based on the extent to which speciating populations are geographically isolated from one another: allopatric, peripatric, parapatric, and sympatric. Speciation may also be induced artificially, through [url=http://en.wikipedia.org/wiki/Animal_husbandry]animal husbandry or laboratory experiments. Observed examples of each kind of speciation are provided throughout.
Electromagnetism is responsible for practically all the phenomena encountered in daily life, with the exception of gravity. Ordinary matter takes its form as a result of intermolecular forces between individual molecules in matter. Electromagnetism is also the force which holds electrons and protons together inside atoms, which are the building blocks of molecules. This governs the processes involved in chemistry, which arise from interactions between the electrons inside and between atoms.
scientists have discovered that simple peptides can organize into bi-layer membranes. The finding suggests a “missing link” between the pre-biotic Earth’s chemical inventory and the organizational scaffolding essential to life.
“This is a boon to our understanding of large, structural assemblies of molecules,” says Emory Chemistry Chair David Lynn, who helped lead the effort, which were collaborations of the departments of chemistry, biology and physics. “We’ve proved that peptides can organize as bi-layers, and we’ve generated the first, real-time imaging of the self-assembly process. We can actually watch in real-time as these nano-machines make themselves.”
Organic – Inorganic Nano-Hybrid Materials
in 1828, a chemist named Friedrich Wöhler accidently created urea. Urea was a compound that mammals produced to get rid of excess nitrogen. Urea is secreted in their urine. Friedrich created it using inorganic (non-living) salts. Everyone was surprised, but chemists then knew that it was possible to create chemicals found in the body using chemicals from the ground or air (non-living sources). So now organic compounds were not defined as only those compounds from organisms, but compounds based on carbon.
Strong diffusional mixing and short delivery times typical for micrometer and sub-micrometer reaction volumes lead to a special situations of self oscillation where the turnover times of individual enzyme molecules become the largest characteristic time scale of the chemical kinetics. Under these conditions, populations of cross-regulating allosteric enzymes form molecular networks that exhibit various kinds of self-organized coherent collective dynamics.

NABT (National Association of Biology Teachers) Position Statement on Teaching Evolution
The frequently-quoted declaration of Theodosius Dobzhansky (1973) that "Nothing in biology makes sense except in the light of evolution" accurately reflects the central, unifying role of evolution in the science of biology. As such, evolution provides the scientific framework that explains both the history of life and the continuing change in the populations of organisms in response to environmental challenges and other factors. Scientists who have carefully evaluated the evidence overwhelmingly support the conclusion that both the principle of evolution itself and its mechanisms best explain what has caused the variety of organisms alive now and in the past.
The principle of biological evolution states that all living things have arisen from common ancestors. Some lineages diverge while others go extinct as a result of natural selection, mutation, genetic drift and other well-studied mechanisms. The patterns of similarity and diversity in extant and fossil organisms, combined with evidence and explanations provided by molecular biology, developmental biology, systematics, and geology provide extensive examples of and powerful support for evolution. Even as biologists continue to study and consider evolution, they agree that all living things share common ancestors and that the process of evolutionary change through time is driven by natural mechanisms.
Evolutionary biology rests on the same scientific methodologies the rest of science uses, appealing only to natural events and processes to describe and explain phenomena in the natural world. Science teachers must reject calls to account for the diversity of life or describe the mechanisms of evolution by invoking non-naturalistic or supernatural notions, whether called "creation science," "scientific creationism," "intelligent design theory," or similar designations. Ideas such as these are outside the scope of science and should not be presented as part of the science curriculum. These notions do not adhere to the shared scientific standards of evidence gathering and interpretation.
Just as nothing in biology makes sense except in the light of evolution, nothing in biology education makes sense without reference to and thorough coverage of the principle and mechanisms provided by the science of evolution. Therefore, teaching biology in an effective, detailed, and scientifically and pedagogically honest manner requires that evolution be a major theme throughout the life science curriculum both in classroom discussions and in laboratory investigations.
Biological evolution must be presented in the same way that it is understood within the scientific community: as a well-accepted principle that provides the foundation to understanding the natural world. Evolution should not be misrepresented as 'controversial,' or in need of 'critical analysis' or special attention for any supposed 'strength or weakness' any more than other scientific ideas are. Biology educators at all levels must work to encourage the development of and support for standards, curricula, textbooks, and other instructional frameworks that prominently include evolution and its mechanisms and that refrain from confusing non-scientific with scientific explanations in science instruction.
Adopted by the NABT Board of Directors, 2011. Revised 1997, 2000, 2004, 2008 and 2011 (Original Statement 1995). Endorsed by: The Society for the Study of Evolution, 1998; The American Association of Physical Anthropologists, 1998.
Evolutionary medicine is the application of modern evolutionary theory to understanding health and disease. It provides a complementary scientific approach to the present mechanistic explanations that dominate en.wikipedia.org..." target="_blank" class="postlink" rel="nofollow">medical science, and particularly modern medical education. Researchers in the field of evolutionary medicine have suggested that evolutionary biology should not simply be an optional topic in medical school, but instead should be taught as one of the basic medical sciences.
Such adaptations concern:
The evolution of pathogens in terms of their virulence, [url=v]resistance to antibiotics, and subversion of an individual’s immune system.
The processes, constraints and trade-offs of human evolution.
The evolved responses that enable individuals to protect, heal and recuperate themselves from infections and injuries such as immunity, fever, and sickness behavior, and the processes that regulate their deployment to maximize fitness.
How past adaptation of early humans to their ancestral environment now affects contemporary humans with their different diet, life expectancy, degree of physical exercise, and hygiene.
Microorganisms evolve resistance through natural selection acting upon random mutation. Once a gene conferring resistance arises to counteract an antibiotic, not only can that bacteria thrive, but it can spread that gene to other types of bacteria through horizontal gene transfer of genetic information by plasmid exchange. It is unclear whether the genetic information responsible for antibiotic resistance typically arises from an actual mutation, or is already present in the gene pool of the population of the organism in question.
For more details on this topic, see antibiotic resistance
The effect of organisms upon their host can vary from being symbioticcommensals that are beneficial, to pathogens that reduce fitness. Many pathogens produce virulence factors that directly cause disease, or manipulate their host to allow them to thrive and spread. Since a pathogen’s fitness is determined by its success in transmitting offspring to other hosts, it was thought at one time, that virulence moderated and it evolved toward commensality. However, this view is now questioned by Ewald.
For more details on this topic, see virulence, virulence factors and optimal virulence
The success of any pathogen depends upon its ability to evade host immunity. Therefore, pathogens evolve methods that enable them to infect a host, and then evade detection and destruction by its immune system. These include hiding within host cells, within a protective capsule (as with M. tuberculosis), secreting compounds that misdirect the host's immune response, binding its antibodies, rapidly changing surface markers, or masking them with the host’s own molecules.
For more details on this topic, see manipulation of the immune system by pathogens, andevasion of the innate immune system
As for the Bacteria, its still bacteria, its changes , regardless of lateral mutation, loss, or any type of supposed gain, its still bacteria. Its not turning into a fish, or a human.
Protozoa (from the Greek words πρωτό, proto, meaning first, and ζωα, zoa, meaning animals; singular protozoon or also protozoan) are a diverse group of single-cell eukaryotic organisms, many of which are motile. Throughout history, protozoa have been defined as single-cell protists with animal-like behavior, e.g., movement. Protozoa were regarded as the partner group of protists to protophyta, which have plant-like behaviour, e.g., photosynthesis.
Protistans are eukaryotes. They have a nucleus, large ribosomes, mitochondria, endoplasmic reticulum, and golgi bodies. Many species have chloroplasts. Some protists divide by way of mitosis, meiosis, or both. The majority of protistians are single-celled, but nearly every lineage also has multicelled forms. Protists are important for the use of food. Saprobes resemble some bacteria and fungi, and some predators and parasites resembles animals. Some are heterotrophs and some are autotrophs. Chytrids, water molds, slime molds, protozans, and sporozans are heterotrophs.

Bacteria have an extremely important place in the evolution of life. Our knowledge of bacteria helps us understand, observe, and investigate evolution. This exhibits explains what we know about the origin of life on Earth and the role bacteria played and still play in this. As described in this Lecture on the Origin of Life all life originated from a common ancestor (Source: UTDallas). Our other exhibit explains how we can observe mutations in bacteria directly.
Archaeabacteria are a diverse group of bacteria (prokaryotes that do not have a nucleus) and are considered a major group unto themselves. This group is called the Archaea (from Greek, 'old') for short and to distinguish them from the other prokaryotes, all other bacteria are then called Eubacteria.
What are Archaea? They are more similar to eukaryotes than to bacteria in several ways: their cell-wall does not contain peptidoglycan (a component of each bacterial cell). There are other characteristics that Archaea share with eukaryotes, however they do not have a nucleus (which all Eukaryotes have). They form a group by themselves.
The Kingdom Monera is the taxonomic kingdom that comprises all prokaryotes: Eubacteria and Archaebacteria. Monera has been contrasted with the kingdoms of eukaryotic organisms (protists, fungi, plants, and animals).Archaebacteria emerged at least 3.5 billion years ago and are the oldest life forms.There are several theories about the exact phylogenetic relationship (what was derived from what) between archaea, eukaryotes, and eubacteria, as can be seen in two versions of the Tree-of-Life. New insights dictate that eubacteria and archaebacteria diverged from one another near the time of the origin of life, and that eukaryotes were derived from eubacteria.

Intellectual arguments have been ignored and thrown to the wind hundreds of pages ago.
This thread is all about intellectual dishonesty, logical fallacies and, uhm... sarcasm
Yes it means that there is a section of the DNA which tells them more detail about the suspect.
Yes an episode of Solved is your best source . They are talking about a 72% chance of the human variable. Meaning.....the suspect is 100% human and 72% likely a black male. Can you not understand what this actually means?
How can you say that when you believe in evolution? How do you not know they didn't evolve into another species?
Humans are 100% genetically identical in DNA compared to other species, except for appearance and genetic defects which actually accounts for a very small difference....ie. .5% of our entire make up which is influenced by environment and parentage.. If your claim, that anyone with different DNA sequences are from a different planet is true, you would have to have a different planet for every variation....i.e. genetic heart disease, hair color, eye color, diabetes, height, weight, etc
Which may mean that parts of the DNA are the same.
Every human on earth can be genetically traced back to common ancestry.
A crow sledding on a roof top to me is not redundant.
Stupid , stupid crows...learning to manipulate their environment...redundant adaptation at it's best. They're definitely not from here!!!!!!
If the larva were a target food, he would have had a naturaly equipped way of getting to them, other then by devising the stick method.
Oh man.... I forgot about that one, thanks! ☆
That raven is clearly just having fun sledding.
These New Caledonian crows are being observed using a twig like skewer to spear beetle larvae for a yummy target food treat.
I'm sure evolutionists will concot a theory about where these new genes came from. What they will say is that the species that used to share them, have all gone extinct
reply to TheJackelantern.
I'm not a religous kind of guy but I think we are a modified creature, not an evolved thing. I don't understand why humans have some DNA which is not shared by any other creature. Please give an example of a trans species, not just a claim of incrementalism, unless you can demonstrate this most basic of evidence I'm afraid I'll have to keep thinking Darwin wasn't exactly right, nor are creationists, We are far too mysterious for that. I do hold a degree in Cultural Anthopology, but I'm not an expert on the way species developed. Just one cat with wings would work just dandy, or even an ape driving a Mercedes and wearing a Rolex, oh I know, a single celled creature whose turgor pressure endurance has changed, that would be pretty easy, just one cell in all of time.
I do know that DNA is sometimes damaged, but that isn't evolution, that is a birth defect, which would be selected out. what is it 223 gene pairs we do not share with any other creature? I know, get the testimony of one single Mitochondria, but know this, Mitochondria are pretty picky about their instructions, but one shouldn't be too hard. Mutants are not evolution, mutants are damaged instruction sets. BTW please try to give a true example of a trans species fossil, just one okay? Not attacks based on some kind of rationalisation which when examined is nothing more than hyperbole. Here's one maybe! How come Goofy (a dog) has a dog named Pluto, is this evolution or slavery?
Your call, if you figure out one fossile of a trans species please U2U me about it, because I honestly don't believe you can, and it really doesn't matter to me, I'm an old guy and I've looked at a bunch of fossils, even have quite a collection, some of the critters are extinct, but they didn't turn into other things, they just died out. I'd especially like for you to show the 223 gene pairs unique to humans in any other thing on earth. Not just argument, we need a true example to certify you as being correct, you have so far offered nothing more than canned arguments based on your mistaken belief that I think some hairy thunderer made everything. Rote recital does not win arguments and frankly you seem not to have offered anything but fluff, sorry, I win.
