The process in which organism with variations most suited to their local environment survive and leave more offspring.

• Natural Selection
• Survival of the Fittest
• Common Descent
• Phenotype

What do we call differences among heritable traits?

• Variation
• Adaptation
• Evolution
• Speciation

What do we call change over time?

• Evolution
• Natural Selection
• Natural Variation

Who would have stated "acquired traits" such as a giraffe needing a long neck so they stretch it over time

• Darwin

• Lamarck

Lamarck’s ideas about evolution include the concept that differences among the traits of organisms arise as a result of

• continual increases in population size.
• the actions of organisms as they use or fail to use body structures.
• an unchanging local environment.
• the natural variations already present within the population of organisms.
