What causes a species to adapt?
In evolutionary theory, adaptation is the biological mechanism by which organisms adjust to new environments or to changes in their current environment. The idea of natural selection is that traits that can be passed down allow organisms to adapt to the environment better than other organisms of the same species.
How do species adapt to survive?
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.
How do animals survive?
Animals need food, water, shelter, and space to survive. Herbivores can live only where plant food is available. Omnivores can live in many places because they eat both plants and animals. Habitat is the physical area where an animal lives.
What is the need for adaptation in animals?
An adaptation is a characteristic that helps an animal survive in its habitat. All animals must be able to obtain food and water, protect themselves from harm, withstand the climate, and reproduce young so the species doesn’t become extinct.
How does an adaptation help an animal survive?
These animals can often change their colors, but they do so to communicate with other members of their species, not as a way to camouflage. All animals have adaptations that allow them to survive, but some adaptations are clearly more interesting than others.
How is a species adapted to its niche?
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.
How does an organism adapt to its environment?
Every organism has a unique ecosystem within which it lives. This ecosystem is its natural habitat. This is where the basic needs of the organism to survive are met: food, water, shelter from the weather and place to breed its young. All organisms need to adapt to their habitat to be able to survive.
How did Charles Darwin contribute to the theory of adaptation?
Although scientists discussed adaptation prior to the 1800s, it was not until then that Charles Darwin and Alfred Russel Wallace developed the theory of natural selection. Wallace believed that the evolution of organisms was connected in some way with adaptation of organisms to changing environmental conditions.
