evolution is the change in the inherited traits of a population from generation to generation. These traits are the expression of genes that are copied and passed on to offspring during reproduction. Mutations in these genes can produce new or altered traits, resulting in heritable differences (genetic variation) between organisms. New traits can also come from transfer of genes between populations, as in migration, or between species, in horizontal gene transfer. Evolution occurs when these heritable differences become more common or rare in a population, either non-randomly through natural selection or randomly through genetic drift.
Natural selection is a process that causes heritable traits that are helpful for survival and reproduction to become more common, and harmful traits to become more rare. This occurs because organisms with advantageous traits pass on more copies of these heritable traits to the next generation. Over many generations, adaptations occur through a combination of successive, small, random changes in traits, and natural selection of those variants best-suited for their environment. In contrast, genetic drift produces random changes in the frequency of traits in a population. Genetic drift arises from the role chance plays in whether a given individual will survive and reproduce.
One definition of a species is a group of organisms that can reproduce with one another and produce fertile offspring. However, when a species is separated into populations that are prevented from interbreeding, mutations, genetic drift, and the selection of novel traits cause the accumulation of differences over generations and the emergence of new species. The similarities between organisms suggest that all known species are descended from a common ancestor (or ancestral gene pool) through this process of gradual divergence.

...then where did all the other animals come from?
and what about the beings from other planets?
you're just creating a level of regress by saying an external source did it...
and you're doing so without any legitimate scientific backing.

I am wondering where ATS'rs stand on Evolution and Creation and the Age of the Earth. These two belief systems have been in a fight since the day the evolution theory was written down. So I am just wondering where the Trained Minds of the ATS boards stood. The two beliefs are pretty easy to understand when you get down to the bottom fo them.
1. All mankind came from Adam and Eve whom God created about 6000 years ago.
2. All mankind came from a rock about 3-4.5 billion years ago.
I will go first and say that I believe the Bible's account of our Origin. Everywhere I look I see designs and I know that there must be a designer. I can not look at it any other way logically, when I see a toaster I see a design and know that somewhere there is designer. I never think that possibly "Billions" of years ago the basic elements in that toaster were all seperate and that over TIME they just became a toaster through trial and error. I don't look at pencils and think that "Billions" of years ago that was just lead and wood and look what "TIME" has done to it. The idea of a helpful mutation is a hard one for me to grasp too, and considering that scientists can not point to a helpful mutation either they probably don't exist. I think that to think that everything we have came out of nothing, turned into rocks, and then into humans after billions of years is a fairytale.
Do you believe in
1. A fairytail that is written by many people, containing parts copied from the egytians stories.
2. That the world has evolved for billions of years based on facts.
Scientist these days DO say that we are not sure how it all started. And the "from a stone" options the christians allways come up with is a childish way of making fun of something you probably dont understand..
