Question

according to darwins theory of natural selection, individuals who survive are the ones best adapted for their environment. their survival is due to which of the following?
lack of competition within the species
lack of competition between different species
possession of inherited adaptations that maximize fitness
possession of adaptations developed during their lifetimes

Explanation:

Darwin's natural selection theory states that heritable traits that increase an organism's fitness (ability to survive and reproduce) are passed on. Survival depends on inherited adaptive traits, not lack of competition or acquired traits (which are not part of Darwin's core natural selection model).

Answer:

possession of inherited adaptations that maximize fitness
