What Evolution covers

Topics in the NEET (UG) 2026–27 syllabus for this chapter.

  • Origin of life
  • Biological evolution and evidences for biological evolution; Darwin's contribution
  • Modern synthetic theory of evolution
  • Mechanism of evolution- variation (mutation and recombination) and natural selection
  • Hardy-Weinberg's principle; adaptive radiation; human evolution

Past NEET questions on Evolution

Try each one, then open the answer and explanation.

Question 1 · NEET 2025

Given below are two statements: Statement I: In the RNA world, RNA is considered the first genetic material evolved to carry out essential life processes. RNA acts as a genetic material and also as a catalyst for some important biochemical reactions in living systems. Being reactive, RNA is unstable. Statement II: DNA evolved from RNA and is a more stable genetic material. Its double helical strands being complementary, resist changes by evolving repairing mechanism. In the light of the above statements, choose the most appropriate answer from the options given below:

  1. A.Both statement I and statement II are correct
  2. B.Both statement I and statement II are incorrect
  3. C.Statement I is correct but statement II is incorrect
  4. D.Statement I is incorrect but statement II is correct
Show answer

Answer: A. Both statement I and statement II are correct

RNA world hypothesis posits RNA as first genetic material because it can store info and catalyze reactions (ribozymes). Statement I is correct. DNA evolved later and is more stable due to complementarity and repair systems; Statement II also correct.

Question 2 · NEET 2025

Sweet potato and potato represent a certain type of evolution. Select the correct combination of terms to explain the evolution.

  1. A.Analogy, convergent
  2. B.Homology, divergent
  3. C.Homology, convergent
  4. D.Analogy, divergent
Show answer

Answer: A. Analogy, convergent

Sweet potato (root tuber) and potato (stem tuber) have different origins but similar functions (food storage). This is analogous structure arising from convergent evolution.

Question 3 · NEET 2024

Match List-I with List-II with respect to convergent evolution: List-I List-II A. Lemur I. Flying phalanger B. Bobcat II. Numbat C. Anteater III. Spotted cuscus D. Flying squirrels IV. Tasmanian tiger cat Choose the correct answer from the options given below:

  1. A.A-III, B-IV, C-II, D-I
  2. B.A-III, B-II, C-IV, D-I
  3. C.A-IV, B-III, C-II, D-I
  4. D.A-IV, B-II, C-III, D-I
Show answer

Answer: A. A-III, B-IV, C-II, D-I

Convergent evolution means unrelated animals evolve similar traits. Lemurs (primates) and Spotted cuscus (marsupial primate-like) are comparable. Bobcat (placental carnivore) matches Tasmanian tiger cat (marsupial carnivore). Anteater (placental) matches Numbat (marsupial anteater). Flying squirrels (placental gliders) match Flying phalanger (marsupial glider).

Question 4 · NEET 2024

What is the correct order (old to recent) of periods in Paleozoic era?

  1. A.Silurian, Devonian, Permian, Carboniferous
  2. B.Silurian, Devonian, Carboniferous, Permian
  3. C.Permian, Devonian, Silurian, Carboniferous
  4. D.Silurian, Carboniferous, Permian, Devonian
Show answer

Answer: B. Silurian, Devonian, Carboniferous, Permian

First recall Paleozoic periods order: Cambrian, Ordovician, Silurian, Devonian, Carboniferous, Permian. From old to recent in question's list: Silurian → Devonian → Carboniferous → Permian.

Question 5 · NEET 2024

Match List-I with List-II: List-I List-II A. Living Fossil I. Elongated canine teeth B. Connecting Link II. Vermiform appendix C. Vestigial Organ III. Echidna D. Atavism IV. Latimeria Choose the correct answer from the options given below:

  1. A.A-IV, B-III, C-II, D-I
  2. B.A-IV, B-II, C-III, D-I
  3. C.A-IV, B-III, C-I, D-II
  4. D.A-III, B-IV, C-I, D-II
Show answer

Answer: A. A-IV, B-III, C-II, D-I

Latimeria (coelacanth) is a living fossil. Echidna is a connecting link between reptiles and mammals. Appendix is a vestigial organ. Elongated canines seen in carnivores represent an atavism when reappearing.
