Answer:
The diagram shows that Some ancestors of Homo sapiens have not yet been identified.
Explanation:
The diagram (see in the picture) shows a common ancestor gave rise to Homo erectus, H. neanderthalis and H.sapiens, the first two hominids, but with evolutionary lines different from H. sapiens. At present it is not known with certainty which were the ancestors of the first individuals of the genus Homo.
The oldest evidence of the presence of H. sapiens places it in Africa (Ethiopia) about 200 years ago, and that it could have been a descendant of the H. heidelbergensis species, which migrated to Africa shortly before becoming extinct. However, the ancestors of today's man have not been clearly identified.
Biological evidence, such as the mitochondrial genome, suggests that there is no evolutionary relationship between H. neanderthalis, H. erectus and H. sapiens, which does not rule out the existence of a common ancestor that originated all three species.
