which of the following may lead to speciation?
a. a group of individuals from a mainland become stranded
b. a population remains unchanged
c. individual leaves on population to join another population
d.none of the above
Homework Answers
Ans . Option (a) is correct
Explanation :- Formation of one or more new species from an existing species is called speciation. They are of 2 types :-
1.Divergent speciation :- when one or more new species are formed from an ancestor species.
a) Allopatric speciation :- When a species split Into 2 or more geographically isolated populations and these population finally form new species.
B) Sympatric speciation :- When sub population becomes reproductively isolated from its parental population.
2) Transformation speciation :- when an ancestor species changes into a new species.

Based on the "Allopatric Speciation" video, which of the following can lead to genetic divergence?
5. Based on the "Allopatric Speciation" video, which of the following can lead to genetic divergence? Select ALL that apply. Select all that apply Founder Effect Gene Flow Natural Selection Mutation Genetic Drift6. There are two isolated populations - Population 1 and Population 2. These populations have been separated for a long period of time. Now, imagine that you bring individuals from these populations together to see if they will interbreed. You find that there is only limited interbreeding between Population 1 and Population 2 and...

The following scenario is partly fictional: One million years ago, a small group of Homo erectus decided to follow a herd of wildebeest on a migratory path that took them much farther north than they had gone before. As they walked and walked, they decided that this new territory looked quite hospitable, and they decided to move their homes. One of the hunters went back to convince a few more Homo erectus individuals to join them. Ultimately, over 500 of...
