Describe the four basic causes of evolution: natural selection, mutation, genetic drift, and gene flow. (please 400-500 response)

19. Variation is important for evolution, because it provides the fitness differences upon which natural selection operates.

19. Variation is important for evolution, because it provides the fitness differences upon which natural selection operates. Sexual reproduction is an important source of variation in plants and animals, but what about asexually reproducing organisms like bacteria? Where does their variation come from? (Concepts: sexual versus asexual reproduction, mechanisms generating allelic variation) 20. The Phoenix Zoo kept the only remaining population of Arabian Oryx for ten years in captivity. Finally, when the captive population was high enough and the habitat was...

Answer parts a and b in regards to natural selection and variation within and between populations....

Answer parts a and b in regards to natural selection and variation within and between populations. Be clear about which part you are answering. a. How does natural selection impact variation within a population? b. How does natural selection impact variation between populations; be specific about this answer (Hint: there's more than one option here).

Describe how natural selection is the process of evolution.

Distinguish group selection theory from Darwinian theory of natural selection

The neutral mutation hypothesis does NOT suggest that: (a) The evolution of most genetic variation in a population is influenced by genetic drift (b) When natural selection is at work on protein variants, it will lead to little variation in the population (c) Most molecular variation is adaptively neutral- for example, most protein variants are functionally equivalent. (d) Natural selection is still an important evolutionary force (e) Genetic variation in a population is maintained mainly by natural selection

Describe the history and the role of evolution and natural selection in ecology.

For natural selection to happen, there must be variation present in a population. This is true because in a population without variation Select one: a. Change between generations can't happen b. If there is only one trait, it must be advantageous, and thus change is not necessary. c. There is no inter-individual competition. d. Offspring never inherit mutations.

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. True or False ? biology involved Evolution and natural selection
