Human Evolution NEET 2026: Assertion Reason on Homo Sapiens Origin

What does this NEET assertion reason question on Homo sapiens origin claim?

Statement I claims modern Homo sapiens first appeared in Australia before spreading to other continents. Statement II states Homo sapiens appeared between 75,000 and 10,000 years ago. The four standard assertion-reason choices are both correct, both wrong, only I, or only II.

How do you solve this human evolution NEET 2026 question using only NCERT lines?

Statement I is incorrect and Statement II is correct, so the answer is D. This matches the official key for +4 marks.

Statement I is incorrect because NCERT places the origin of modern Homo sapiens in Africa followed by migration. Statement II is correct because NCERT explicitly lists the late Pleistocene period as 75,000–10,000 years ago. Independent checking of each statement before combination leads to option D. This method follows the verified official NCERT solution exactly.

What single reasoning error turns a correct human evolution NEET answer into a wrong one?

Treating the two statements as linked events instead of evaluating them separately against NCERT lines produces the wrong option.

Students often recall Australian fossils of earlier hominins and wrongly assign them to modern sapiens origin. This skips the exact paragraph on the Out-of-Africa model. Failing to cross-verify the continent in Statement I against the exact paragraph on Out-of-Africa model turns a clear D into A or C. Read Statement I alone and check only the continent first, then check Statement II dates only. No linkage is allowed.

Which medium-level practice questions from the Genetics and Evolution chapter test the same skill?

Question 1: Arrange the chronological order of Homo erectus, Homo neanderthalensis and Homo sapiens with cranial capacities (correct order and values 900 cc, 1400 cc, 1350 cc).

Correct order per NCERT: Homo erectus (900 cc), Homo neanderthalensis (1400 cc), Homo sapiens (1350 cc).

Question 2: Assertion–reason on whether Homo sapiens arose in Africa and migrated to Australia last (both statements correct but reason does not explain assertion).

Both true, reason not explanation. The textbook lists the African origin first and migration second without calling Australia the “last” step as a causal link.

Which exact NCERT phrases on human evolution decide every similar NEET 2026 question?

Modern Homo sapiens arose in Africa and moved across continents is the exact NCERT line that kills Statement I. During the ice age between 75,000–10,000 years ago pins Statement II as correct.

The NCERT comparison that distinguishes sapiens from erectus and neanderthalensis is:

• Homo erectus appears before sapiens and has 900 cc cranial capacity.
• Homo neanderthalensis shows 1400 cc cranial capacity and lived in Europe and Asia.
• Homo sapiens shows 1350 cc cranial capacity, originated in Africa, and has no Australian origin listed.
• No mention of Australian origin for modern sapiens anywhere in the chapter.

Memorise these lines from pages 142–143.

How can you finish any assertion-reason question on human evolution in 45 seconds for NEET 2026?

Read both statements independently against NCERT page 142–143. Mark continent first, then time period; never assume linkage. This checklist solves the question in 45 seconds.

Biology section is 360 marks. One correct assertion-reason equals +4 with –1 risk. Apply the same two-step check to any statement pair in the unit. For similar statement-based practice, see correct statements on loop of Henle for human physiology NEET 2026.
