Question
According to the evolutionary theory, formation of a new species is generally due to
Options
sudden creation by nature
accumulation of variations over several generations
clones formed during asexual reproduction
movement of individuals from one habitat to another
Solution
accumulation of variations over several generations
Explanation -
According to the evolutionary theory, the accumulation of variations (resulting from errors in DNA copying and sexual reproduction) over several generations along with the operation of natural selection leads to the formation of new species.
