What is NOT a requirement for evolution by natural selection to occur?
a) Traits must be inherited
b) Traits must influence reproductive success
c) Inherited traits must have variation within the population
d) Characteristics that are favored (fitness) relate to the immediate environment
e) Variations will appear that will allow the survival of the species in future, unforeseen, circumstances.

Solution
* Ans: e) Variations will appear that will allow the survival of the species in future, unforeseen, circumstances.
There are 4 conditions required for the evolution by natural selection to occur:
1. Reproduction.
2. Heredity.
3. Variation in fitness or organisms.
4. Variation in individual characters among members of the population.
* Ans: d) with Alfred Wallace, published a mechanism for adaptive change, natural selection, and proposed a \"tree of life\"
In 1858 Charles Darwin and Alfred Russel Wallace published a new evolutionary theory. Darwin proposed common descent and a branching tree of life (two different species share a common ancestor). Darwin, based on his natural selection theory synthesized a broad range of evidence from animal husbandry, biogeography, geology, morphology, and embryology.
