Evolution is the process in which inherited traits become more or less prevalent in a population over successive generations. Over time, this process can lead to speciation, the development of new species from existing ones.
Evolutionary biologists are now looking for a new mechanism, one that can overcome genetic constraints and other chemical-oriented barriers that have been identified in recent years. Until this mechanism is found, the theory of evolution (a theory which has enjoyed prominence in biological circles for over 100 years) simply lacks feasibility, and thus, credibility.
If one species evolved into another, "linking" species would have to have existed in profuse quantities at various points in earth's history. But profuse quantities of missing links which could be termed "indisputable evidence" have never been found.
Hmm....ok, well, it's fairly clear that you don't operate in the same reality as I do, and that you don't understand what exactly the words "evolution", "genome", and "mutation", mean. I suggest you buy a good solid genetics textbook, such as "Genetics" by Pierce. Good book. Read up on some of this stuff before posting about aliens, hehe.

For something new in the human genome to be obtained something new or altered must be introduced.
Certain diseases are the result of genetic adaptations against other diseases; the best example being sickle-cell anemia, a double dose of a trait which in single-dose confers immunity against malaria.

Genetics, Inheritance & Variation
Another example of codominance is sickle cell haemoglobin in humans. The gene for haemoglobin Hb has two codominant alleles: HbA (the normal gene) and HbS (the mutated gene). There are three phenotypes:
HbAHbA - Normal. All haemoglobin is normal, with normal red blood cells.
HbAHbS - Sickle cell trait. 50% of the haemoglobin in every red blood cell is normal, and 50% is abnormal. The red blood cells are slightly distorted, but can carry oxygen, so this condition is viable. However these red blood cells cannot support the malaria parasite, so this phenotype confers immunity to malaria.
HbSHbS - Sickle cell anaemia. All haemoglobin is abnormal, and molecules stick together to form chains, distorting the red blood cells into sickle shapes. These sickle red blood cells are destroyed by the spleen, so this phenotype is fatal.

From Maps to Medicine: The Impact of the Genome Project by Dr. Beverly S. Emanuel, Director of Human Genetics Center; Charles E. H. Upham Chair in Pediatrics
The easiest genetic diseases to understand are those caused by a single gene that has gone awry. Single gene diseases include relatively rare disorders such as cystic fibrosis, phenylketonuria, hemophilia, sickle cell anemia and Huntington's disease. In a sense, the genes for these diseases act like a single time bomb ticking away inside the DNA double helix.
Much more common, and far more complicated, are the diseases caused by malformations in several or many genes that influence each other in complex ways that are poorly understood. Hypertension, diabetes, rheumatoid arthritis, multiple sclerosis, schizophrenia, Alzheimer's, coronary artery disease and numerous other diseases that afflict our species are caused by the interactions of multiple different genes. Each individual gene has a relatively modest effect, but together they determine whether someone is going to develop a disease or not. Multiple gene diseases or what we call polygenic diseases are far harder to understand than those which are caused by single genes.
Complicating matters even further, most genetic diseases result from an interplay between an inherited predisposition and factors in a person's external environment and lifestyle. It's not just the individual cards that you have been dealt, but it also depends upon how you play the hand. It's important to keep this in mind to avoid the dangers that can potentially arise from biological determinism--thinking that everything about an individual is predetermined by the DNA code written in his or her genes.
The Sixth Extinction
So what is the Sixth Extinction? When is it coming? And what is its cause? "It's the next annihilation of vast numbers of species. It is happening now, and we, the human race, are its cause," explains Dr. Richard Leakey, the world's most famous paleoanthropologist. Every year, between 17,000 and 100,000 species vanish from our planet, he says. "For the sake of argument, let's assume the number is 50,000 a year. Whatever way you look at it, we're destroying the Earth at a rate comparable with the impact of a giant asteroid slamming into the planet, or even a shower of vast heavenly bodies." The statistics he has assembled are staggering. Fifty per cent of the Earth's species will have vanished inside the next 100 years; mankind is using almost half the energy available to sustain life on the planet, and this figure will only grow as our population leaps from 5.7 billion to ten billion inside the next half-century. Such a dramatic and overwhelming mass extinction threatens the entire complex fabric of life on Earth, including the species responsible for it: Homo sapiens.

New Frontiers: Evolution and the Future The Sixth Extinction by Niles Eldredge
Because of the lack of any direct evidence for evolution, evolutionists are increasingly turning to dubious circumstantial evidences, such as similarities in DNA or other biochemical components of organisms as their "proof" that evolution is a scientific fact.
We have noted from the statements of leading evolutionary scientists that no true vertical evolution from one kind of organism to a more complex kind has ever been observed in all human history.
1. Thus, in spite of much evidence that the earth has always had a significant quantity of free oxygen in the atmosphere,3 evolutionists persist in declaring that there was no oxygen in the earth's early atmosphere. However, this would also be fatal to an evolutionary origin of life.
2. The energy available on a hypothetical primitive Earth would consist primarily of radiation from the sun, with some energy from electrical discharges (lightning), and minor sources of energy from radioactive decay and heat. The problem for evolution is that the rates of destruction of biological molecules by all sources of raw energy vastly exceed their rates of formation by such energy. The only reason Stanley Miller succeeded in obtaining a small amount of products in his experiment was the fact that he employed a trap to isolate his products from the energy source.
3. Let us suppose that, as evolutionists suggest, there actually was some way for organic, biologically important molecules to have formed in a significant quantity on a primitive Earth. An indescribable mess would have been the result. In addition to the 20 different amino acids found in proteins today, hundreds of other kinds of amino acids would have been produced.
4. It is said that DNA is the secret of life. DNA is not the secret of life. Life is the secret of DNA. Evolutionists persistently claim that the initial stage in the origin of life was the origin of a self-replicating DNA or RNA molecule. There is no such thing as a self-replicating molecule, and no such molecule could ever exist.
5. If DNA somehow evolved on the earth it would be dissolved in water. Thus water and many chemical agents dissolved in it, along with ultraviolet light would destroy DNA much faster than it could be produced by the wildest imaginary process.
What are the cellular agents that are necessary for DNA repair and survival? DNA genes! Thus, DNA is necessary for the survival of DNA! But it would have been impossible for DNA repair genes to evolve before ordinary DNA evolved and it would have been impossible for ordinary DNA to evolve before DNA repair genes had evolved.
The present state of the universe and the laws that govern it contradict all evolutionary theories concerning its origin.

Different species would not be able to mate, and all of us can obviously mate with anyone else of the opposite sex.

So, basically, your articles are bunk. They represent good theory, absolutely, but not applied genetics. I'm sure cross-breeding does occur, but it rarely successful, happens very rarely, and has not happened in humans for nearly 5-6 million years (before we were modern humans).
Humanzee -Wiki
However, despite speculation, no case of a human-chimpanzee cross has ever been confirmed to exist in modern times. This doesn't make it entirely impossible; Chinese scientists at the Shanghai Second Medical University in 2003 successfully fused human cells with rabbit eggs. The embryos were reportedly the first human-animal chimeras successfully created.
