- A classic example is shown by the melanistic (dark) phenotype of the peppered moth (Biston betularia), which increased in numbers in Britain following the Industrial Revolution as dark-coloured moths appeared cryptic against soot-darkened trees and escaped predation by birds.

Oct 19, 2023 · An example of a structural adaptation is the way some plants have adapted to life in dry, hot deserts. Plants called succulents have adapted to this climate by storing water in their short, thick stems and leaves. Seasonal migration is an example of a behavioral adaptation.
Oct 19, 2023 · One example of behavioral adaptation is how emperor penguins in Antarctica crowd together to share their warmth in the middle of winter. Scientists who studied adaptation prior to the development of evolutionary theory included Georges Louis Leclerc Comte de Buffon.

An adaptation, or adaptive trait, is a feature produced by DNA or the interaction of the epigenome with the environment. While not all adaptations are totally positive, for an adaptation to persist in a population it must increase fitness or reproductive success. All offspring, whether formed sexually or asexually, inherit their traits from their p...
Genetic Mutation and Recombination
Deoxyribonucleic acid, or DNA, is the molecule that carries the information necessary for creating and maintaining life. DNA is made from a series of nucleotides, 4 small chemicals which chain together. The sequence of these chemicals can be read by specialized enzymesand organelles within cells to produce new proteins. These proteins have various functions, and determine how the cell functions within its environment. Since the first proteins and cellular constituents aggregated to form the f...
Changes in Environment
Changes in the environment are second major category of adaptation. In many cases the epigenome is as or more important that the DNA itself. Large environmental changes, such as a change in ocean temperature or acidity, can affect a great number of species. As the environment changes, the proteins of the organisms start to function differently. Changes to the DNA or to how the epigenome interacts with the new environment can lead to a novel adaptation. For instance, life on Earth currently de...
Rhinocerous Beetle
If you’ve ever seen a Rhinoceros Beetle, you’ve probably wondered what it uses those huge horns for. Seen below is a male Rhino Beetle, with its distinctive headgear. Like all arthropods, the beetle is divided into segments. These various sections are very responsive to adaptation. In the Rhino Beetle, the head section has developed these large thorns. The male beetles use these large obtrusions to fight each other, in competition for females. It is presumed that ancestral beetles had little...
Digestive Tract in Mammals
If you were to dissect various mammals, you would find something very peculiar in the size and composition of their digestive tract. Carnivores, like wolves and cats, have very short and simple digestive tracts. In fact, the more carnivorous an animal, the shorter and simpler the digestive tract is. Meat and animal products are easily digested. The adaptation of a short gut allows these animals to quickly process the energy out of their meaty meal, before it starts to rot in their gut. Herbiv...
1. A fox has a litter of 3 kits. 1 of the kits is randomly eaten by an eagle. Only 1 of the remaining kits learns how to successfully feed itself, the other starves to death. Which of the following could be considered an adaptation? A. The learning that allowed the survivor to feed itself B. Any genetic basis for the intelligence of the surviving f...
For example, changes in climate can affect how easy it is for organisms to find food or water. After an environmental change, traits that help organisms survive and reproduce in the new environment become more common.
- How long does it take for an organisms to adapt to its environment?It varies with the creature and the change to the environment.

In this unit, you'll learn about how species evolve and adapt to their surroundings. From the way populations change to survive in new environments, to the fascinating processes of speciation and extinction, you'll gain a deeper understanding of the natural world and the forces that shape it.
Adaptations help an organism survive and/or reproduce in its current environment. Adaptations can take many forms: a behavior that allows better evasion of predators, a protein that functions better at body temperature, or an anatomical feature that allows the organism to access a valuable new resource — all of these might be adaptations.
