Question

Arrange the following in chronological order : 
(a) Australopithecus 
(b) Homo Erectus 
(c) Homo Sapiens
Code :

Accepted Answer

Here's the explanation:

Option 1: (a), (b), (c) is the correct chronological order because:

*   **(a) Australopithecus:** This genus represents some of the earliest known hominins. Fossil evidence places them as existing roughly between 4 million and 2 million years ago. They are considered a key step in the evolution from ape-like ancestors to modern humans.

*   **(b) Homo Erectus:** *Homo erectus* evolved after *Australopithecus*, appearing approximately 1.9 million years ago and existing until about 110,000 years ago. They are known for their larger brain size, more human-like body proportions, and use of fire. They represent a more advanced stage of human evolution compared to *Australopithecus*.

*   **(c) Homo Sapiens:** *Homo sapiens*, which includes modern humans, evolved most recently. The earliest *Homo sapiens* fossils date back approximately 300,000 years.

Therefore, the sequence Australopithecus -> Homo Erectus -> Homo Sapiens accurately reflects the order in which these hominin species appeared on Earth.

Why the other options are incorrect:

*   **Option 2: (a), (c), (b):** This is incorrect because *Homo sapiens* evolved *after* *Homo erectus*, not before.

*   **Option 3: (b), (a), (c):** This is incorrect because *Homo erectus* evolved *after* *Australopithecus*, not before.

*   **Option 4: (b), (c), (a):** This is incorrect because *Homo erectus* and *Homo sapiens* both evolved *after* *Australopithecus*.
