Directions: Perform the task below based on your understanding on the topic " Mechanisms 'of Evolutionary Change" . There are four factors that can change the allele frequencies of a population namely Natural Selection, Mutations, Genetic Drift and Gene Flow. Make a creative outline summarizing the processes happened in these mechanisms of evolutionary change (use separate sheet if
Q:need help with question We looked at how the beliefs of the Theory of Special Creation were challenged by Descent with Modification. Even before Lamarck and Darwin proposed that species do change over time, what belief of the Theory of Special Creation had already been challenged? Species do not change Lineages do not split Each species is separately created Each species is independently created Earth and life are young

Please help with the following: Lactase persistence is an adaptation to milk drinking that has developed since the beginning of agriculture ~10 KYA. What is the relationship between the alleles driving this ability in European, Indian and African populations? A. One allele is responsible for lactase persistence in Europeans and Indians because of where agriculture originated and was introduced through migration. routes. B. The allele responsible for lactase persistence in all three populations is the same allele on the LCT gene. C. Different alleles are responsible for lactase persistence in each population. D. One allele is responsible for lactase persistence in Europeans, but other alleles cause the trait in Indian and African populations. E. One allele is responsible for lactase persistence in Africans, but other alleles cause the trait in European and Indian populations.
