Answer: According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.
Organisms with the most favourable traits will increase their success rate in a particular environment. Organisms with favorable traits are more likely to reproduce and pass on their traits than organisms without favorable traits, allowing it to survive.
