Which of the following statements are true about Evolution? (3)
Random mutations called adaptations increase an organisms fitness and chance of surviving long enough to pass on those traits to the next generation.
It takes place through natural selection.
Organisms with a small range of tolerance are best suited for survival.
It can happen in the lifetime of an organism.
It takes thousands or even millions of years to occur.
