Question

Evolution of human appears parallel to the progressive development of brain and language skills. As such, the evolution of individual species in the sequence of their appearance is :

• A. {Ramapithecus} $\longrightarrow$ {Homo habilis} $\longrightarrow$ {Homo erectus} $\longrightarrow$ Neanderthal $\longrightarrow$ {Homo sapiens}
• B. {Homo habilis} $\longrightarrow$ {Homo erectus} $\longrightarrow$ {Ramapithecus} $\longrightarrow$ Neanderthal $\longrightarrow$ {Homo sapiens}
• C. {Homo sapiens} $\longrightarrow$ {Ramapithecus} $\longrightarrow$ {Homo habilis} $\longrightarrow$ Neanderthal $\longrightarrow$ {Homo erectus}
• D. Neanderthal $\longrightarrow$ {Ramapithecus} $\longrightarrow$ {Homo habilis} $\longrightarrow$ {Homo erectus} $\longrightarrow$ {Homo sapiens}

Answer 1

The Correct Option is A

Step 1 : Understanding the Question:
The question asks for the correct chronological sequence of human ancestors, beginning with early ape-like forms and progressing to modern humans. This sequence reflects the evolutionary transition toward increased cranial capacity and complex behaviors.
Step 2 : Key Formulas and Approach:
The approach involves ordering human ancestors based on their fossil age and brain capacity:
1. {Ramapithecus}: Approx 15 million years ago (mya).
2. {Homo habilis}: Approx 2 mya (Brain: 650-800cc).
3. {Homo erectus}: Approx 1.5 mya (Brain: 900cc).
4. Neanderthal: 100,000 to 40,000 years ago (Brain: 1400cc).
5. {Homo sapiens}: Modern man.
Step 3 : Detailed Explanation:

Ancient Hominids: {Ramapithecus} lived roughly 15 million years ago. Although they still had many ape-like features, they walked more upright and were more "man-like" than their predecessors. They represent the oldest ancestor in this list.

Handy Man: About 2 million years ago, {Homo habilis} emerged. They were the first hominids recognized as making and using stone tools. Their brain capacity was relatively small, between 650 and 800cc.

Upright Man: Fossils discovered in Java revealed that {Homo erectus} lived around 1.5 million years ago. They had a much larger brain (900cc) and were likely the first hominids to master the use of fire.

Cave Dwellers: Living in Europe and parts of Asia until 40,000 years ago, Neanderthals possessed large brains (1400cc), used hides for clothing, and practiced burying their dead.

Modern Man: Modern humans ({Homo sapiens}) appeared in Africa and spread across the globe during the last Ice Age (75,000–10,000 years ago), ultimately developing complex societies and language.

Step 4 : Final Answer:
The chronological evolutionary sequence is {Ramapithecus} $\rightarrow$ {Homo habilis} $\rightarrow$ {Homo erectus} $\rightarrow$ Neanderthal $\rightarrow$ {Homo sapiens}. This matches the sequence in option (A).
