The most accepted line of descent in human evolution is:
a. Australopithecus → Ramapithecus → Homo sapiens → Homo habilis
b. Homo erectus → Homo habilis → Homo sapiens
c. Ramapithecus → Homo habilis → Homo erectus → Homo sapiens
d. Australopithecus → Ramapithecus → Homo erectus → Homo habilis → Homo sapiens.
The answer is the option
(c) Ramapithecus→Homo habilis→Homo erectus→Homo sapiens
Explanations:
The most widely accepted line of descent in human evolution illustrates a progression of hominid species leading to modern humans. It begins with Ramapithecus, an early primate that lived approximately 10 to 12 million years ago and is often considered one of the first ancestors of humans. This is followed by Homo habilis, which emerged around 2.4 million years ago and is recognized for its use of simple tools. Next in the lineage is Homo erectus, appearing around 1.9 million years ago; this species is notable for its increased brain size and the development of more advanced tools and the use of fire. Finally, the evolution culminates in Homo sapiens, the species to which all modern humans belong, which emerged roughly 300,000 years ago and is characterized by complex language, culture, and advanced technological innovation.
