Speciation and Animal Behavior Concepts

What is the process called when new species are formed from an older species?

• Evolution

• Speciation

• Adaptation

• Extinction

Which of these can act as a natural barrier to separate animal populations?

• A large city

• A deep river

• A tall fence

• A busy road

What two main things help new species form when groups of animals are separated?

• Changes in weather and food supply

• Different types of predators and prey

• Mutations and natural selection

• Human activities and pollution

Após longos períodos isolados por uma barreira geográfica uma população pode diferenciar-se da outra. Essa é a especiação

What type of speciation happens when new species form in the same geographic area without being separated by a physical barrier?

• Allopatric speciation

• Parapatric speciation

• Sympatric speciation

• Hybrid speciation
