best evidence for the theory of evolution?

Humans have very diverse traits today.

B)

There appear to be missing links in the evolutionary chain.

Life on earth has been found to date back billions of years.

D)

DNA found in older primate fossils resemble those of humans today.

Answer:D

DNA found in older primate fossils resemble those of humans today.

Explanation:

Charles Darwin was first to establish and scientifically validate the process of evolution in living organisms. His work mainly focused on how different organisms living in different areas are evolved and what similarities their fossils share. He compiled his findings in the book "The Origin of Species by Means of Natural Selection". He often visited an island "Galapagos" and compared the fossil record of finches with the other island. He was able to identify similarities among finches from different islands. He further looked at the differences and argued that these were due to evolutionary reasons. Briefly, he mentioned in his book that the ancestors of finches from both islands were probably the same, however, due to different climates in different islands, the descendants were evolved in a different way.

The same principle is applied to humans when we compare the fossil record of earlier primates with modern humans. This has been also proven by DNA analysis. The DNA sequence, obtained from earlier primates, matches with modern humans especially in conserved regions (e. g. 18S gene). This indicates that modern-day humans have been evolved due to changes in climates and regions.
