Descent with modification" describes... Choose the best option. Group of answer choices Any evolution Evolution by natural selection Phenotypic plasticity Evolution by genetic drift

Which of the following evolutionary mechanisms can drive genetic divergence after the genetic isolation created by allopatry or sympatry? Select ALL that apply. 08 Natural selection Mutation Gene flow Genetic drift

List the premises of evolution by natural selection. What is the inevitable outcome?Variation; heritability; “struggle”/context; differential survival/reproduction

What is the role of variation in evolution If heterozygosity is reduced what happens to the potential for evolution? The phenotype and genotype of a population is due to a mosaic of random and directed processes some of these have to do with history.some are related to adaptation etc. As completely as possible,discuss the role of chance and direction in evolution and in determining the phenotype of a population

Siberian tigers are the largest of all tiger species because only the largest individual are able to survive the cold harsh winters of north eastern Russia. what type Mechanism evolution is this Natural Selection Genetic drift Gene Flow Bottleneck Effect Founder Effect Sexual Selection

Natural selection can be defined as: chance differences in organism traits. the chance for species numbers to increase rapidly. the processes that lead individuals to resemble their parents. the differential survival and reproduction of individuals. the genetic fixation of species.

A farmer wants to make a better corn plant that produces more and bigger kernels. In the chart, information is provided on two ways organisms can change over time. Natural Selection Selective Breeding Humans are not involved in the evolution process Human intervention is involved More generations are involved in natural selection, so it is a slower process Selective breeding is a faster process Survival of the fittest increases species' chance for survival Adaptations may not necessarily improve survival Mutations that result in natural selection occur randomly The desirable charactenstics are artificially chosen What is the best way for the farmer to improve his crop and why? Use evidence from the table to support your reasoning. Please write in complete sentences.

A massive mudslide takes out half of the trees growing on a mountain side. The trees that are left happen to have slightly thicker branches than the original population. Which type of mechanism evolution is this Natural Selection Genetic drift Gene Flow Bottleneck Effect Founder Effect Sexual Selection
