Question

Australopithecus was the first of our ancestors known to:
A. Move out of Africa and spread throughout Eurasia.
B. Have definitely diverged from the apes.
C. Leave written records.
D. Have a brain size equal to or larger than ours.

Answer 1

Hint: Australopithecus afarensis is one of the world's longest-lived and best-known early human species—paleoanthropologists have unearthed remains from more than 300 individuals. This species is found between 3.85 and 2.95 million years ago in Eastern Africa (Ethiopia, Kenya, Tanzania), this species lived for more than 900,000 years, which is over four times as long as our species was around.
Complete Step-by-step answer:Australopithecus afarensis was known to be a long-lived early "ape-man" found in South Africa. It was documented to have originated in the final epoch of the Tertiary period - the Miocene epoch. The Miocene epoch lived approximately 22 - 5 mya and observed the evolution and emergence of man-like apes. The end of the Tertiary period marks the beginning of the Quaternary period. This period is split into two epochs – Holocene and Pliocene. The Pliocene epoch noticed many significant events in the evolutionary history of the world. It witnessed the emergence of the genus Homo and the emergence of herbs. The Holocene epoch is the one that persists even today. This epoch is characterised by the supremacy of man and the evolution of monocots along with the dominance of herbs.
Therefore the correct answer is Option B.
Note: The fossil of the Australopithecus species was first found in 1924 in South Africa. They resided on the ground, used stones as weapons, and walked straight. They were four feet tall and weighed 60-80 pounds. These were 1.2 meters tall. They lived on the African mainland. They had huge jaws and human-like teeth.
