According to the theory of natural selection, some individuals more likely than others to survive and reproduce because they:

• pass on to their offspring their newly acquired traits.
• are better adapted to their environment than others and will pass on those adaptations to future offspring.
• do not pass on newly acquired traits.
• produce fewer offspring than others in the same environment.

Lamarck’s theory of evolution includes the concept that new traits appear because:

• natural variation and natural selection.
• use and disuse
• the environment is unchanged
• the natural variations are present within a population.

When every organism of a species has died.

• Evolution
• Natural Selection
• Extinction
• Artificial Selection
