Which of the following statements about human evolution is correct? A) The upright posture and enlarged brain of humans evolved simultaneously. B) Fossil evidence indicates that early anthropoids were arboreal, were cat-sized, and lived about 35-45 million years ago. C) Human ancestors were virtually identical to chimpanzees. D) Human evolution occurred by anagenic change within an unbranched lineage. E) Modern humans are the only human species to have evolved on Earth. Please explain reasoning. Thank you. Solution B.Fossil evidence indicates that early anthropoids were arboreal, were cat-sized, and lived about 35-45 million years ago. Reason:-The fossil record of Family Felidae extends to the Late Eocene, 34 million years ago.The first known feline was Aelurogale. Its descendent, Proailurus, gave rise to the major branches of the cat family we see today.Miacoid species gave rise to Proailurus which appeared about 30 million years ago, and is generally considered the first true cat.There were other cat-like species before Proailurus.Archeological evidence shows a relationship between man and cat for the past 8,000 years..

Solution
B.Fossil evidence indicates that early anthropoids were arboreal, were cat-sized, and lived about
35-45 million years ago.
Reason:-The fossil record of Family Felidae extends to the Late Eocene, 34 million years
ago.The first known feline was Aelurogale. Its descendent, Proailurus, gave rise to the major
branches of the cat family we see today.Miacoid species gave rise to Proailurus which appeared
about 30 million years ago, and is generally considered the first true cat.There were other cat-like
species before Proailurus.Archeological evidence shows a relationship between man and cat for
