Question

Which of the following is not a tenet of Darwinism?

(a) Struggle for existence

(b) Variation

(c) Natural selection

(d) Inheritance of acquired character

WBBSE Class X Life Science 04 (a) Evolution 01 Mark 2023

Answer

(d) Inheritance of acquired character

Explanation

Darwin’s theory of evolution includes the concepts of variation, struggle for existence, and natural selection as the main mechanisms driving evolution. The inheritance of acquired characters was proposed by Lamarck, not Darwin. This idea suggested that traits acquired during an organism’s life could be passed on to offspring, which Darwinism does not accept.
