NEET 2017 Biology Evolution Questions

Use this page to connect the official 2017 paper with current Biology practice. NeetVellum does not claim a chapter appeared in that paper until the official question and final key have been mapped.

What to master

evidence, mechanisms, population genetics, speciation and human evolution.

Original practice preview

These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.

Example 1 · difficulty 3/5

A few birds carrying only a small, unrepresentative sample of their mainland population's alleles are blown to a remote island and establish a colony. Many generations later, the island population's allele frequencies differ markedly from those of the mainland. This is best described as:

A. Gene flow from the mainland into the island population
B. Directional selection favouring rare mainland alleles
C. Founder effect, a special case of genetic drift
D. Bottleneck effect caused by a crash in population size

Example 2 · difficulty 4/5

Arrange the following stages of human evolution in the correct order of INCREASING cranial capacity: A. Homo habilis, B. Australopithecus, C. Neanderthal man, D. Homo erectus

A. A → D → B → C
B. B → A → D → C
C. B → D → A → C
D. D → A → B → C

Example 3 · difficulty 4/5

Australian marsupials underwent extensive radiation, and several of them strikingly resemble placental mammals found elsewhere — for example, the Tasmanian wolf resembles the placental wolf. The resemblance between each marsupial and its placental counterpart arose through:

A. Divergent evolution from a recent common ancestor
B. Inheritance of habits acquired in similar habitats
C. Hybridisation between marsupial and placental stocks
D. Convergent evolution under similar selection pressures

Frequently asked questions

Are these official NEET 2017 Biology Evolution PYQs?

No. The previews are original NeetVellum practice questions. A historical item receives a PYQ label only after its official paper and authoritative final answer key are attached. Use the official archive for the source paper.

How should I use the NEET 2017 paper?

Solve the official paper under its original timing, verify against the final key, classify every miss, and then use the linked current-syllabus practice bank to repair the exposed concept.
