Those that are not well adapted don't survive and reproduce. An adaptation is any characteristic that increases fitness, which is defined as the ability to survive and reproduce. 2.

A reasonable definition for a species is: O A distinct kind of animal. O A group of living things with functionally similar traits, for example, all creatures that can fly. O A group of living things with taxonomically similar traits. O A group of taxonomically similar living things in which all healthy members can interbreed and produce fertile offspring. QUESTION 8 If microevolution is any change in the gene pool of a breeding population, then macroevolution is: O A change in the genetic makeup of group that eventually results in the development of a new species. O The mass exctinction of old species to make way for new. O Changes in the physical environment at large. O When microevolution happens on a large scale. * QUESTION 9 What is the primary cause of speciation? O Extinction. O Overpopulation. O Environmental change.

In the mountain environment (mostly grey) what would someone expect to happen to the the mouse population in the simulation? Group of answer choices 1. the population would stay at the same frequencies because mutations aren't happening 2.the population would have 2 different species: brown and grey mice 3.the population would go down to only a few mice and they would all be brown 4.the population would have a higher % of grey mice than brown mice by the end

rn.genetics.utah.edu/content/evolution/barriers/ 3. Reproductive isolation reduces GENE FLOW between populations This means that each subpopulation evolves separately and can result in a new species. Isolating mechanisms fall into the following categories. For each category, identify which example(s) from the chart above matches it. Reproductive isolation: physiology prevents mating or producing fertile offspring. Ex. shape or reproductive organs not compatible Temporal isolation - timing isolation, individuals mate at different times of year. Example. frogs that mate in may versus those that mate in July. Behavioral isol -behaviors prevent mating. Ex. birds recognize mates by songs or dance Still confused?

Fixity of Species refers to… Group of answer choices A-the theory that species exist at a fixed location along a physiological continuum B-the fact that species are defined by fixed adaptations to their direct environment C-the theory presented by Thomas Malthus that population densities of any given species are most affected by mortality and fertility rates D-the pre-darwinian notion that species, once created, can never change E-the late 19th century concept that because mendelian traits are fixed they are evidence that variation within and between species are designed by God specifically for those species

What are some notes or take aways about this model? Model 1 – PopGen Fish Pond This model is an agent-based population genetics simulation. The program contains the tools to conduct virtual experiments violating all the assumptions of Hardy-Weinberg theory (small population, selection, mutation, migration, and non-random mating).
