Answer 1

"Survival of the fittest" is a phrase that originated from Darwinian evolutionary theory as a way of describing the mechanism of natural selection. This phrase states that the organisms are naturally selected by the ability of the organism to survive in the changing environmental conditions. One of the examples for this phrase is: ln a habitat there are bed bugs and green bugs. The birds prefer the taste of the bed bugs, so soon there are many green bugs and few red bugs. The green bugs reproduce and make more green bugs and eventually, there are no more bed bugs.
