what is survival of the fittest? dna comparison new traits and genes being developed the strongest species will live the longest organisms best suited for their environment will survive reproduce

Explanation:

"Survival of the fittest" is a concept from evolutionary biology. It means that organisms best suited for their environment will survive and reproduce. This is because they have traits that give them an advantage in their specific ecological niche. For example, in a cold environment, animals with thicker fur (a beneficial trait) are more likely to survive the cold (the environmental challenge) and pass on the genes for thick fur to their offspring.

Answer:

Organisms best suited for their environment will survive and reproduce.
