Question

Formation of new species due to gradual changes in the course of evolution from
the existing species.
a) Genetic drift
b) Fossils
c) Variation
d) Speciation​

Answer 1

Answer:

D. Speciation

Explanation:

Mutations are the great source in producing genetic variations in a living organism. Due to which the species of new characters are formed through the process of speciation

Answer 2

formation of new species due to gradual change in the course of evolution from the existing species is known as speciation.

Option (d)

Explanation:

• The new species is formed due to a large amount of change in the genetic sequence of the chromosomes of the individual. in every different individual there is a slight amount of variation.
• When the variation is huge we say it is a genetic drift.
• Genetic drift over a large amount of time results in the change in the chromosomes of an individual resulting in a new sequence of chromosomes having much altered genes. This results in the formation of a new species.
