Speciation and Reproductive Isolation

2. What is Speciation?
Creating a new species

3. How Speciation Occurs
When a group in a population are separated and can no longer reproduce a new species is formed

4. Ways to create a new species
Reproductive Isolation
Geographical Isolation
Temporal Isolation
Behavioral Isolation
Populations separated by geographical barriers like water, canyons, and mountains
Populations separated by time like nocturnal, diurnal, months, years
Populations separated by behaviors like mating calls, physical traits, mating dances

5. Geographic Isolation
No mating because one species gets separated by a barrier. Over time, can lead to two different species.

6. Behavioral Isolation
No mating because one does not desire the courtship behavior of the other one. Over time, can lead to two different species

7. Temporal Isolation
No mating because one reproduces at different times of day, month, year. Over time, can lead to two different species.
