Which of the following is an example of a selection pressure?
Having longer fur than the rest of your species
Having larger horns than the rest of your species
A change in temperature
Being brighter in colour than the rest of your species
Individuals who have a selective advantage are
More likely to survive and pass on their alleles.
Less likely to survive and pass on their alleles
What name is given to the formation of a new species?
Natural Selection
Speciation
Selective Advantage
Mutation
What is the first stage in speciation?
