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

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?

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

What evidence did Georges Cuvier present that contradicted one of Jean-Baptiste Lamarck’s ideas? he argued that specimens in the fossil record never changed much, so evolution was not occurring he demonstrated that the Indian elephant and the African elephant were two different species he claimed that divine creation was necessary to explain the origin of a new species he argued that natural catastrophes, like floods and ice ages, were common in the history of life he identified fossil specimens of two large, extinct mammal species (the mammoth and the mastodon)

In which type of classification system are names assigned only to groups that include a common ancestor and all of its descendants?   Question 30 options:   a system based entirely on evolutionary history   a system based solely on cellular structures   a system that groups organisms based solely on similar morphologies   a system that groups organisms based on similar roles in the environment
