Variation happens randomly in a population, which means:
Some individuals are better adapted to exist in their environment than others are.
it is not something caused by the organism on purpose
survive and reproduce
reproduction of organisms exhibiting genetic differences due to mutations and genetic recombinations
Present-day organisms on Earth developed from earlier, distinctly different organisms.
Environment
millions
plants with deeper roots
