A small population of wood rats boarded a ship leaving Europe and ended up in South America where they began breeding. Which type of Mechanism evolution is this. Natural Selection Genetic drift Gene Flow Bottleneck Effect Founder Effect Sexual Selectio

A yellow mouse blends into a yellow sandy beach area while a white mouse stands out.  The yellow mice survive and reproduce more often than the white mice. what type of agent of evolution is this and why

What did the Scottish geologist James Hutton claim about a possible evolutionary mechanism similar to natural selection (many years before Charles Darwin and Alfred Russel Wallace)? selection for heritable variation could improve neither varieties nor species of plants and animals artificial selection of crops and livestock improves plants and animals more than natural selection only natural selection, not artificial selection, could lead to improved plant and animal species only artificial selection, not natural selection, could lead to improved plants and animal species selection for heritable variation could improve varieties, but not species, of plants and animals

Which of the following forces of evolution is considered purely random? natural selection non-random mating genetic drift O mutation O migration

A population of plants live in a valley. In this population there are plants with red flowers, purple flowers, and blue flowers. One day there is a mudslide and all of the plants purple flowers are killed leaving only red and blue flowered plants alive in the population. This is an example of which mechanism of evolution? Group of answer choices Artificial section Gene flow Sexual selection Genetic drift Natural selection

A group of one species of bacteria are exposed to an antibiotic.  The normal bacteria die but some are resistant to the antibiotic and start multiplying.  The resistant bacteria flourish and now make up the majority of the population.  This is an example of what?     Speciation     Reduction of Gene Flow     Natural Selection     Geographic Isolation

What piece of evidence for evolution was not available in Darwin's time, but has since corroborated his ideas? fossil evidence vestigiality shared developmental pathways DNA similarities OO00

Which of these is needed for natural selection to occur? O genetic variation asexual reproduction environmental stability genetic engineering
