Humans and Chimpanzees are related.

Since you have not implied any religious ideology or belief so far I am going to give you the benefit of the doubt and assume you understand how evolution and natural selection works. For starters two species that recently diverged from an original species will tend to share more DNA then other species that diverged earlier in the past. You may have heard or seen something that says humans and chimpanzees share 98% of our DNA and then somewhere else it says humans and chimpanzees share 96% of our DNA, Both of these numbers are accurate, The reason being is how genomes are compared, When the genomes are sequenced the amount of genes the genomes share are counted, Chimpanzees share around 98% of genes with modern humans, Of course you then compare the order in which the genes are placed in the genomes, Chimps share a 96% gene order with modern humans. This is important because shared genes don't tend to just come from anywhere, If two species share the majority of the same genes and gene order that imply's "evolutionary wise" that most of these genes belonged to a common ancestor of the two species before diverging into two separate populations which went on there own evolutionary paths. Secondly from a physical structure standpoint humans and chimpanzees are VERY similar, Although humans evolved to be bipedal and apes non-bipedal they share roughly the same "humanoid" body structure such as two arms, And two hands with five fingers "which also have finger nails" two legs, With two feet with five toes, They have a neck which leads to a head with a cranium, Two eyes, Two nose holes and a mouth. Humans along with chimpanzees "and the other great apes" also have a ear shape which is universal to us, I don't know why no body ever brings this up in evolution debates :/ we also share the same amount of body hair per square inch with chimpanzees "given much of ours is under our skin and much smaller" my point is humans and chimpanzees share a very similar body structure which was likely similar to what the human/chimpanzee common ancestor had. Secondly we have measured mutation rates and how genomes change over time, We can use this along with genetic markers to determine when two species diverged from a common ancestor, Using this we are able to determine that. Africans and Europeans split around 50, 000 years agoArchaic Humans split from homo heidelbergensis around 300, 000 years agoHomo Erectus and homo heidelbergensis split around 1, 200, 000 years agoHomo Habilis and Homo Erectus split around 1, 800, 000 years agoThe Human and chimpanzee linage split off from a common ancestor around 6, 000, 000 years agoThe common ancestor of gorillas and chimpanzees split around 8, 000, 000 years agoThe point is we can determine with genetics and mutation rates "including the fossil record which is also consistent with these genetics" when two species diverged from a common ancestor at some point in the past, But I must explain that the numbers above don't tell when the species themselves came into existence, But when the populations that would become these species diverged from each other. As to why humans and chimps split off around six million years ago still does not have a conclusive answer, The best answer we have at the moment corresponds to the fact that northern and central Africa started becoming dryer roughly around the same time the human/chimpanzee divergence seems to have happened. The idea is that one population of "CHLCA" was left stranded out on the new African plains "which had little to no trees" while another population of "CHLCA" remained in the dense forest environment somewhere in Africa, The population that remained in the dense forest environment went on there own evolutionary path as creatures structurally and neurology built to live in the trees, The "CHLCA" population left out on the African plains however too went down their own evolutionary path, Do to the lack of trees they were forced to move about the ground more, This often required standing upright in order to see possible dangers and the direction in which you were heading, This is believed to have led to bipedalism an evolutionary feature unique to humans and bonobos, The lack of trees meant less food which encouraged this population to go after more live gain "protein" this eventually lead to this population loosing alot of hair over time as its a horrible thing to have when you sweat. Long story short you end up with two closely related species with two very different evolutionary history's. http://humanorigins. Si. Edu/education/introduction-human-evolutionhttp://humanorigins.
