Speciation

Question 1

What is a species

Answer 1

A group of similar organisms that can reproduce to give fertile offspring

Question 2

What is speciation

Answer 2

The development of new species

Question 3

When does speciation occur

Answer 3

When populations of the same species become so different that they can no longer successfully interbreed to produce fertile offspring

Question 4

How does speciation occur due to natural selection and isolation

Answer 4

A population of species can be isolated when ther is a physical barrier like mountains of lakes
Conditions on either side of the barrier will be different
This means the populations will adapt to different environments due to natural selection
Eventually the different populations will have changed so much that they cannot interbreed as 2 new species have developed

Question 5

Who developed the idea of speciation

Answer 5

Alfred russel Wallace
