An inherited trait that increases a population's chance of

survival and reproduction

• Niche

• Speciation

• Variations

• Adaptations

The environment selects individuals whose variations make them better adapted to survive

• Natural Selection

• Speciation

• Geograhic Isolation

• Mutations

Over many generations, favorable adaptations appear and unfavorable ones disappear, leading to new species

• Adaptation

• Speciation

More offspring are born in a population than can survive to reproduce

• Overproduction

• Mass production

• Niche

Consists of interbreeding populations of organisms that produce healthy, fertile offspring

• Species

Offspring struggle with each other to get food and shelter

• Speciation

• Competition

• Overproduction

• Variation

Occurs when a barrier (mountain, river) divides a population leaving the species isolated and adapting to its environment
