Question

New species develop due to

• A. Isolation and mutation
• B. Competition and mutation
• C. Isolation and competition
• D. Isolation and variation

Answer 1

The correct option is A Isolation and mutation

Accumulated random changes within separate isolated populations due to genetic drift are not shared and eventually, lead to incompatible reproductive differences between them thus leading to new species.

Mutation is a permanent alteration of the nucleotide sequence of the genome of an organism or extrachromosomal DNA or other genetic elements which lead to new species

So, the correct answer is 'Isolation and mutation'
