Type answer here. 14 3 Consider the four postulates of natural selection. 2) Some of the trait diffs are heritable (pass traits down) 3) survival and reproductive success is highly variable. 4) subset of individuals that survive best and produce most offspring is not a random sample. Natural selection. individuals with heritable traits produce more surviving offspring. fitness.Darwin was able to formulate his theory of evolution and natural selection using these four observations.

Lamarck state that the evolution of the giraffe is an example of his four postulates. According to Lamarck, the ancestors of giraffes were similar to the horse.

The trait must have caused the organisms to evolve because it made the organisms that had it more fit for survival.
