Evolution Previous Year Questions — NEET Biology

3 past-year Evolution questions from NEET (Biology).

Q140 (2024)

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:
  1. $\text{Homo habilis} \rightarrow \text{Homo erectus} \rightarrow \text{Ramapithecus} \rightarrow \text{Neanderthal} \rightarrow \text{Homo sapiens}$
  2. $\text{Ramapithecus} \rightarrow \text{Homo habilis} \rightarrow \text{Homo erectus} \rightarrow \text{Neanderthal} \rightarrow \text{Homo sapiens}$
  3. $\text{Homo sapiens} \rightarrow \text{Ramapithecus} \rightarrow \text{Homo habilis} \rightarrow \text{Neanderthal} \rightarrow \text{Homo erectus}$
  4. $\text{Neanderthal} \rightarrow \text{Ramapithecus} \rightarrow \text{Homo habilis} \rightarrow \text{Homo erectus} \rightarrow \text{Homo sapiens}$
### Related Formula $\text{Ramapithecus} \rightarrow \text{Australopithecines} \rightarrow \text{Homo habilis} \rightarrow \text{Homo erectus} \rightarrow \text{Neanderthal} \rightarrow \text{Homo sapiens}$ ### Core Logic The correct chronological sequence of human evolution based on fossil records and brain capacity is: 1. *Ramapithecus* (~15 mya) 2. *Homo habilis* (650–800 cc) 3. *Homo erectus* (~900 cc) 4. Neanderthal man (1400 cc) 5. *Homo sapiens* (Modern human) ### Step 1: Verification Matching with Option (2): Ramapithecus $\rightarrow$ Homo habilis $\rightarrow$ Homo erectus $\rightarrow$ Neanderthal $\rightarrow$ Homo sapiens. ### Pattern Recognition Sees: "evolution of individual species sequence". Shortcut: R $\rightarrow$ H.h. $\rightarrow$ H.e. $\rightarrow$ N $\rightarrow$ H.s. ### Evaluation Rubric / Model Answer null ### Chapter Mix Class 12 Biology: Evolution

Q174 (2024)

Which of the following is not an example of convergent evolution?
  1. Eyes of octopuses and mammals
  2. Fore limbs of whales and bats
  3. Wings of butterflies and birds
  4. Flippers of penguins and dolphins
### Related Formula $\text{Homologous Organs (Forelimbs of Whales/Bats)} \rightarrow \text{Divergent Evolution}\\ \text{Analogous Organs} \rightarrow \text{Convergent Evolution}$ ### Core Logic Forelimbs of whales and bats have similar anatomical internal structure (humerus, radius, ulna, carpals, metacarpals) derived from a common ancestor but perform different functions. They are homologous organs representing DIVERGENT evolution, not convergent evolution. All other options (eyes of octopus/mammals, wings of butterfly/birds, flippers of penguin/dolphins) are analogous organs representing convergent evolution. ### Step 1: Conclusion Forelimbs of whales and bats is an example of divergent evolution. ### Pattern Recognition Sees: "NOT an example of convergent evolution". Shortcut: Look for homologous organs $\rightarrow$ Forelimbs of mammals (whales and bats). ### Evaluation Rubric / Model Answer null ### Chapter Mix Class 12 Biology: Evolution

Q179 (2024)

Match List I with List II with respect to chronology of evolution of life forms: <div style="overflow-x: auto; margin: 1rem 0;"><table style="width: 100%; border-collapse: collapse; text-align: left; font-size: 14px;"><thead><tr><th style="border: 1px solid #888; padding: 8px;">List-I</th><th style="border: 1px solid #888; padding: 8px;">List-II</th></tr></thead><tbody><tr><td style="border: 1px solid #888; padding: 8px;">(A) About 65 mya</td><td style="border: 1px solid #888; padding: 8px;">(I) Jawless fish probably evolved</td></tr><tr><td style="border: 1px solid #888; padding: 8px;">(B) About 500 mya</td><td style="border: 1px solid #888; padding: 8px;">(II) The dinosaurs suddenly disappeared from the earth</td></tr><tr><td style="border: 1px solid #888; padding: 8px;">(C) About 350 mya</td><td style="border: 1px solid #888; padding: 8px;">(III) Seaweeds and few plants probably existed</td></tr><tr><td style="border: 1px solid #888; padding: 8px;">(D) About 320 mya</td><td style="border: 1px solid #888; padding: 8px;">(IV) Invertebrates were formed and became active</td></tr></tbody></table></div> Choose the correct answer from the options given below:
  1. A(II), B(IV), C(I), D(III)
  2. A(II), B(IV), C(III), D(I)
  3. A(I), B(II), C(III), D(IV)
  4. A(III), B(IV), C(I), D(II)
### Related Formula $\begin{aligned} \text{65 mya} &\rightarrow \text{Extinction of Dinosaurs}\\ \text{500 mya} &\rightarrow \text{Invertebrates active}\\ \text{350 mya} &\rightarrow \text{Jawless fish evolved}\\ \text{320 mya} &\rightarrow \text{Seaweeds and early plants} \end{aligned}$ ### Core Logic Matching geological time milestones in evolution: * (A) About 65 mya $\rightarrow$ Dinosaurs suddenly disappeared from the earth (II) * (B) About 500 mya $\rightarrow$ Invertebrates were formed and became active (IV) * (C) About 350 mya $\rightarrow$ Jawless fish probably evolved (I) * (D) About 320 mya $\rightarrow$ Seaweeds and few plants probably existed (III) ### Step 1: Result The correct combination is A(II), B(IV), C(I), D(III). ### Pattern Recognition Sees: "65 mya 500 mya 350 mya 320 mya". Shortcut: 65 mya = Dinosaurs disappearance (A-II); 500 mya = Invertebrates (B-IV). ### Evaluation Rubric / Model Answer null ### Chapter Mix Class 12 Biology: Evolution
