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:

Solution & Explanation

Core Logic

The correct chronological order in which human evolution took place (from oldest to most recent) is:

  • Ramapithecus (about 15 mya)
  • Australopithecines (about 2 mya)
  • Homo habilis (first human-like hominid, brain capacities 650-800cc)
  • Homo erectus (about 1.5 mya, brain around 900cc)
  • Neanderthal man (100,000-40,000 years ago, brain 1400cc)
  • Homo sapiens (modern man, arose around 75,000-10,000 years ago)
Step 1: Final Conclusion

Looking at the options, the sequence that perfectly follows this timeline is: Ramapithecus → Homo habilis → Homo erectus → Neanderthal → Homo sapiens.

Pattern Recognition

Ramapithecus is the oldest (first). Homo sapiens is the newest (last). Only option 2 has this correct start and end.

Q174 neet_2026_03_may_morning Evidences for Evolution
Which of the following is not an example of convergent evolution?
  • A. Eyes of octopuses and mammals
  • B. Fore limbs of whales and bats
  • C. Wings of butterflies and birds
  • D. Flippers of penguins and dolphins

Solution

Core Logic

Fore limbs of whales and bats share a similar anatomical structure (homologous organs) but have adapted for different functions (swimming vs flying). This indicates common ancestry, which is an example of divergent evolution, not convergent evolution. Eyes of octopus/mammals, wings of butterflies/birds, and flippers of penguins/dolphins are analogous structures formed due to convergent evolution.

Pattern Recognition

Homologous organs = Divergent evolution (same origin, different function). Analogous organs = Convergent evolution (different origin, same function).

Q179 neet_2026_03_may_morning Geological Time Scale
Match List I with List II with respect to chronology of evolution of life forms
List-IList-II
A. About 65 myaI. Jawless fish probably evolved
B. About 500 myaII. The dinosaurs suddenly disappeared from the earth
C. About 350 myaIII. Seaweeds and few plants probably existed
D. About 320 myaIV. Invertebrates were formed and became active
Choose the correct answer from the options given below:
  • A. A(II), B(IV), C(I), D(III)
  • B. A(II), B(IV), C(III), D(I)
  • C. A(I), B(II), C(III), D(IV)
  • D. A(III), B(IV), C(I), D(II)

Solution

Core Logic

About 65 mya - The dinosaurs suddenly disappeared from the earth. About 500 mya - Invertebrates were formed and became active. About 350 mya - Jawless fish probably evolved. About 320 mya - Seaweeds and few plants probably existed.

Step 1: Final Conclusion

Thus, the matching is A-II, B-IV, C-I, D-III.

Pattern Recognition

Dinosaur extinction is definitively marked at 65 mya. Jawless fishes are 350 mya.
