1. False
Speciation is the formation of new species from a population of species. This process has three main stages: isolation, where the population is separated; adaptation, where the isolated population adapts to the new environment; and reproductive isolation, where the two populations can no longer breed to produce fertile offspring.

2. Behavioral isolation
This occurs when there is a difference in mating rituals or other behaviors which prevent interbreeding.
