If you look at the universe and study the universe, what you find is that there is no evidence that we need anything other than the laws of physics and the other laws of science to explain everything we see. There's absolutely no evidence that we need any supernatural hand of god. -- Lawrence Krauss, World-Renowned Physicist
There is probably no other notion in any field of science that has been as extensively tested and as thoroughly corroborated as the evolutionary origin of living organisms. -- Encyclopedia Britannica
FAITH. No one word personifies the absolute worst and most wicked properties of religion better than that. Faith is mind-rot. It’s the poison that destroys critical thinking, undermines evidence, and leads people into lives dedicated to absurdity. It’s a parasite regarded as a virtue. -- PZ Myers
Religion is the antithesis of science, an anesthetic for the mind that disables critical thought and encourages the acceptance of inanity as fact, and wishful thinking as evidence. -- PZ Myers

The DNA evidence leaves us with one of the greatest surprises in biology: the wall between human, on the one hand, and ape or animal, on the other, has been breached. The human evolutionary tree is embedded within the great apes."

"Geneticists have come up with a variety of ways of calculating the percentages, which give different impressions about how similar chimpanzees and humans are. The 1.2% chimp-human distinction, for example, involves a measurement of only substitutions in the base building blocks of those genes that chimpanzees and humans share. A comparison of the entire genome, however, indicates that segments of DNA have also been deleted, duplicated over and over, or inserted from one part of the genome into another. When these differences are counted, there is an additional 4 to 5% distinction between the human and chimpanzee genomes."
"No matter how the calculation is done, the big point still holds: humans, chimpanzees, and bonobos are more closely related to one another than either is to gorillas or any other primate. From the perspective of this powerful test of biological kinship, humans are not only related to the great apes – we are one. The DNA evidence leaves us with one of the greatest surprises in biology: the wall between human, on the one hand, and ape or animal, on the other, has been breached. The human evolutionary tree is embedded within the great apes."
Take your complaints to the Smithsonian National Museum of Natural History.
Now watch the science denier go running to his favorite crackpots.

Primate Family Tree

"Due to billions of years of evolution, humans share genes with all living organisms. The percentage of genes or DNA that organisms share records their similarities. We share more genes with organisms that are more closely related to us."
"Humans belong to the biological group known as Primates, and are classified with the great apes, one of the major groups of the primate evolutionary tree. Besides similarities in anatomy and behavior, our close biological kinship with other primate species is indicated by DNA evidence. It confirms that our closest living biological relatives are chimpanzees and bonobos, with whom we share many traits. But we did not evolve directly from any primates living today."
"DNA also shows that our species and chimpanzees diverged from a common ancestor species that lived between 8 and 6 million years ago. The last common ancestor of monkeys and apes lived about 25 million years ago."
