Introduction to Evolution Benchmark

What does evolution mean?

• Humans come from monkeys

• Species change and adapt over time

• If an organism doesn't use it, they'll lose it

• Only the most fit survivie

Sometimes referred to as "survival of the fittest," this process allows those traits which are most favorable to be passed on to the next generation and those which are not to be eliminated.

• gene flow
• natural selection
• mutation
