can you give some evidences that can prove that humans evolve from our common ancestor?

Answer 1

Just looking at other primates like chimpanzees or gorillas for example shows us that we share similarities with them as oppose to something like a turtle or a fish. Our skeletal system looks similar. All primates have 5 fingers. A human's DNA and a chimpanzees is something like 98 percent identical. This is also true for gorillas and humans. But since you said ancestors I suppose you mean extinct primates like neanderthals, homo erectus, and homo habilis etc. When looking at their physical characteristics such as their bones which have been found as fossils we can see that they are clearly primates and share similarities to modern humans. The difference is of course that we are far more intelligent and therefore more advanced due to our larger brains.

As far as evidence that supports evolution...in the present day living things are found to be born with mutations or mistakes. Mistakes or mutations is natures way of giving variability to a species. If the "mistake" is beneficial to the organism he/she can pass it on to his/her offspring. Viral infections like HIV modify genomes which is another example of how a species genome can be modified.

Answer 2

On the way to work today, I noticed that I look a heck of a lot like all the other human beings. Having a common ancestor (even if it was some time between 70,000 and five million years ago) is an excellent explanation for this observation.

Even the Bible says we have a common ancestor -- Noah.

Answer 3

Common ancestor compared to what? You and your cousins share a set of grandparents so you could say you have common ancestors with your cousins.

The same for second cousins. You share great grandparent ancestors with your second cousins.

You probably look more like your first cousins than your second cousins.

Keep going back..... You don't need any more "proof" than that of a common ancestor. The farther back you go, the fewer traits you share with your ever more distant cousins. Second cousins might share an ancestor from 50 years ago. Think how different you would be if it was 5 million years.

Answer 4

we share 98% of our genetic code with apes, as well as sharing many common physiological features like the shapes of out skulls, pelvis etc..
Fossils have similarly been found having similar features and can be dated to show the progression of early primates into modern primates, including man.
