Which theory tells about adaptation?
Correct answer: A. Darwin's natural selection
- A. Darwin's natural selection
- B. Lamarck's theory
- C. Hardy-Weinberg's principle
- D. None of these options are correct
Explanation
Option A: This is the correct option, Darwin suggested that populations of individual species become better adapted to their environments through natural selection.Option B: Lamarck suggested that physical changes in organisms during their lifetime could be transmitted to their offsprings, this does not talk about adaptation and is hence not the correct option.Option C: This suggested that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.Option D: Option A is the correct option.

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.

Analogous structures are produced as a result of:
There existed two varieties of female freshwater Mollusks in which some were streamlined and some had a high bulge. Over the generations, male freshwater Mollusks learned that high bulge favors more production of offspring. So they started preferring to mate with females having high bulge as compared to streamlined. Will this affect Hardy Weinberg Equilibrium in the population?
