Which of the following ideas proposed by Charles Darwin provided the first objective way to measure small evolutionary changes from one generation to the next? common descent biogenesis evolution abiogenesis populational change

The next five questions (questions 11-15) are related to each other. Read all of the scenarios very carefully and in order and select the correct answer. A population of 10,000 blue grasshoppers lives on an island. Most members of the population live among the grasses because they are not very good climbers. Some grasshoppers live in the trees because they are good climbers. One year, a short-legged mouse arrived at the island and ate all grasshoppers within its reach, thus totally wiping out the grasshoppers living in the grasses. Luckily, those grasshoppers that were good climbers were spared. This story is an example of Gene Flow Founder Effect C Natural Selection Genetic Drift

A population of birds lives on a mountain. In this population, there are red-winged birds, orange-winged birds, and blue-winged birds. A predatory snake eats more of the blue-winged birds because they are not well camouflaged on the red and orange plants that grow on the mountain. This is an example of which mechanism of evolution? Group of answer choices Gene flow Cryptic coloration Natural selection Sexual selection Genetic drift

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 Selection
