NEET BIOLOGY

Detailed explanation-1: -From TEDEd, there’s a five finger trick for understanding and remembering the five processes-small population, non-random mating, mutations, gene flow, adaptation-that impact evolution (ie. the changes in the gene pool of a population from generation to generation).

Detailed explanation-2: -Five different forces have influenced human evolution: natural selection, random genetic drift, mutation, population mating structure, and culture.

Detailed explanation-3: -Each of the five elements, setting, characters, problem, events, and solution can be written on each of the corresponding fingers.

Detailed explanation-4: -About 380 million years ago, quadrupedalism can have six, seven even eight fingers depending on different species. Due to evolution, it has been simplified into a five-finger structure which ensure both the flexibility and the grasping ability. This is the reason why we all have five fingers not six or four.
