Formation and emergence of new species

Question 1

speciation

Answer 1

speciation occurs when a population becomes reproductively isolated from other members of the same species . over time the two separated populations begin to diverge in genetic composition and physical appearance.

Question 2

sympatric speciation

Answer 2

over time, one species splits into two species that occupy the same area, but are prevented from breeding by behavioural factors

Question 3

allopatric speciation

Answer 3

a geographical barrier splits one part of a population from another

Question 4

how speciation occurs

Answer 4

natural selection continues to occur in the different environments and the two populations develop different genotypes and phenotypes. each is now a different species.

Question 5

speciation due to geographic isolation

Answer 5

geographic isolation refers to a situation where a species becomes separated by a physical barrier, and each group diverges along a separate evolutionary path
