1 a. Does natural selection cause mutations? Does evolution cause mutations? 1b.Mutation in and of itself is not evolution. What must happen for evolution to occur? 1 c. Give an example in which the relative fitness of a heterozygote is greater than the relative fitness of either of the homozygotes.

Evolution by natural selection is an emergent property of the structure of DNA. According to the theory, individuals vary in form and behaviour in heritable ways, which leads to different survival rates of their offspring. True or False? The type of evolutionary relationship shown in phylogenetic trees is called horizontal gene transfer. Endosymbiosis is not an example of horizontal gene transfer.

Use the 9 steps of evolution by natural selection to explain how the body type of Homo erectus & heidelbergensis (both had very similar bodies) could then change to a Homo neanderthalensis body. Begin with a specific morphological change in the body of a Homo heidelbergensis, combined with the relevant selection pressures and adaptive benefits, to work your way through each of the nine steps to explain the evolution of Neandertals.
