"Natural selection and speciation leads to evolution". Justify this statement.
Answers
Answer:
Explanation:
It is true that natural selection & speciation leads to evolution.
i. The origin of species from pre-existing one leads to speciation of species
ii. Some individuals will be better adapted to the environment than others and will therefore be more likely to breed and pass on their alleles to the next generation, which is called as variation.
iii. This means that each population will begin to evolve different adaptations to suit their environment
iv. With time, this genetic drift, will accumulate different genetic variations leading to evolution of species.

The better adapted organisms would, thus, survive and pass on their traits to next generation, gradually leading to evolution. ... Thus, we can say that both natural selection and speciation lead to the evolution of species on earth.
