Natural selection-

Natural selection, the process by which organisms better adapted to their environment tend to survive and produce more offspring, is a fundamental mechanism in evolution, driving the adaptation of species over time. This process results in the survival and reproduction of individuals with advantageous traits, leading to changes in the genetic makeup of populations. Charles Darwin's groundbreaking observations on natural selection stemmed from his recognition of variations among species and his hypothesis that those best adapted to their environment would have a higher chance of survival and passing on advantageous traits to their descendants. For instance, a deer's evolution of antlers, camouflage fur, …show more content…
This color-changing ability, known as camouflage, allows frogs to blend in seamlessly with their surroundings, making it difficult for predators to spot them. In contrast, frogs with bright colors may use their vibrant hues as a warning to predators of their toxicity or distastefulness, a defense mechanism known as aposematism. By utilizing different coloration strategies, frogs are able to navigate their habitats successfully and increase their likelihood of survival in the wild. Ultimately, the diverse coloration of frogs not only adds to the beauty of these creatures, but also plays a crucial role in their survival in their natural …show more content…
The same results were shown for the yellow frogs as well, but there were only a few differences, such as that for group 1, instead of going down on the second year, it went down on the third year and then became extinct, and for group 2, their yellow frogs also had good survival rates but went extinct on the 7th year. However, the green frogs in both groups had excellent survival rates and reproduction rates, as from the 7th and 8th years on, they had not decreased their rates. Overall, it can be concluded that the green frogs in both groups were more resilient to extinction compared to the red and yellow frogs. This suggests that there may be certain factors contributing to the survival of green frogs that are not present in red and yellow

Natural Selection Bean Lab Report

In the Natural Selection Bean Lab experiment we learned how natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in heritable traits of a population over time. During the experiment a predator of the seed “Us” In which we picked beans from two different environment, one dirt the other sand. If the color of the bean resembles the color of their environment darker colors will have a tougher chance…

Natural Selection Results Essay

are not, are unable to survive. This process is known as natural selection. This process explains how Charles Darwin’s theory of evolution can occur. The purpose of completing this lab was to demonstrate that natural selection results in populations different than the original because of the adaptations that occur as a result of the population’s environment. During the lab, we pretended that we were “birds” that eat “beetles”. In the lab, the beetles were represented by the different colored dots…

Mice Adaptation Lab Report

mice adaptation through natural selection. Adaptation is the process by which, as a result of natural selection, organisms become better matched to their environment. One example of an adaptation which many animals have is the ability to camouflage. When an animal is able to camouflage, it is able to blend in with its habitat, making it hard for predators to spot them. Organisms can adapt to their environment through the process of natural selection. Natural selection is a mechanism of evolution…

The purpose of the game is to illustrate the basic principles and some of the general effects of evolution by natural selection. Natural selection acts at the level of individuals. It is the individual organism that lives or dies, reproduces or fails to reproduce because of its characteristics. When more…

The volcanic rock darkened as it cooled many years ago. A predator is any organism that actively hunts for its food, or prey. In the video, the rock pocket mouse is the prey while birds are the predators. The mouse is referred to as the “snicker bar of the desert” in the video. Typically, the rock pocket…

PREDATOR-PREY RELATIONS LAB Background Research: Predators and prey are organisms that interrelate, and they can influence on another’s success in reproduction. Predators are organisms that consume other organisms-their prey. These two organisms evolve together. They live in an environment where they must develop certain adaptations to survive. When an adaptation is developed, it gives an organism certain physical characteristics that create an advantage for survival and can come to dominate…
