They have quickly changed their biological makeup to suit their environments

Detailed explanation-1: -This happens by the process of natural selection. By natural selection, the nature of the species gradually changes to become adapted to the niche. If a species becomes very well adapted to its environment, and if the environment does not change, species can exist for a very long time before they become extinct.
Detailed explanation-2: -A biome is an area classified according to the species that live in that location. Temperature range, soil type, and the amount of light and water are unique to a particular place and form the niches for specific species allowing scientists to define the biome. However, scientists disagree on how many biomes exist.
Detailed explanation-3: -They have five basic needs: air, warmth, sunlight, water, and nutrients. How well these needs are met in a given location depends on the growing season and soil quality, both of which are determined mainly by climate. The growing season is the period of time each year when it is warm and wet enough for plants to grow.
Detailed explanation-4: -Why do different biomes have different characteristic organisms? Each biome has its particular set of environmental conditions. What can cause variation-for example, species composition-among plant and animal communities within biomes? Local differences, (example: soil types, elevation, and when exposure.)
Detailed explanation-5: -The revolution of our planet around the Sun and the tilt of axis cause annual variations in the intensity and duration of temperature, resulting in distinct seasons. These variations together with annual variation in precipitation account for the formation of major biomes such as desert, rain forest and tundra.
