What is the conditions for natural selection?Show answer
Natural selection requires four things, and a complete answer states all of them.
What is fitness?Show answer
In biology, fitness means reproductive success, not physical strength. A fit individual is one that leaves more surviving, fertile offspring. A trait that helps an organism survive is only favoured if it also leads to more offspring; survival without reproduction does not increase fitness.
