Darwin's concept of "survival of the fittest" refers to how organisms with traits that are better suited to their environment are more likely to survive and reproduce, passing on these advantageous traits to their offspring. This process leads to the gradual evolution and adaptation of species to their specific environments over time.
Charles Darwin referred to this ability as "natural selection." It is the process by which certain traits or characteristics that help an organism survive and reproduce in its environment become more common in a population over time. Natural selection is a key mechanism of evolution.
Certain chemicals and radiation in the environment can cause a reaction or mutation in an organism. Such changes may alter organisms genotype or phenotype. Chemicals that induce changes in organisms DNA is called mutagens.
Genes play a critical role in evolution by influencing an organism's traits and characteristics. Changes in genes over generations (mutations, genetic drift, etc.) can lead to new variations that may be advantageous in certain environments, thus driving evolution. The environment also plays a significant role by selecting for certain traits that enhance an organism's survival and reproduction, shaping the direction of evolution.
Organisms that are able to self-regulate their internal conditions within certain parameters, such as homeostasis, can reach equilibrium. This includes many animals, plants, and bacteria that can adjust their physiological processes to maintain stability in response to changes in the environment.

a niche
df
The skin is the boundary which separates an organism from its environment. But this barrier that keeps you on the inside and the germs on the outside must also allow certain exchanges between the organism and the environment, for survival.
A organism with traits that are suited to a certain environment have a better chance of surviving than organisms who's traits are not suited for the environment.
A niche is the role an organism has in the environment . for example some organism's niche is to hunt and kill certain animals and that balances the population within the ecosystem .
Innate behavior results from the interaction between an organism's genetic make-up and its environment. The genetic programming of an organism determines how it will respond to certain stimuli from its environment in a predictable way.

Perception is a process by which an organism recieve certain information about environment. Perception is always based on sensation.
Certain animals adapt to certain environment by certain beneficial and natural traits or features in them and thus the environment gradually becomes its natural habitat. This particular features are in much excess in Homo Sapiens than other organisms and so it is probably believed that by virtue of these features they have overcame the adverse situations perpetrated from the changing weather and climatic conditions. This can be best understood if you read the " The Evolution Of Species" which is a famous book written by an environmentalist, Charles Darwin by framing the experiences of his travel in his ship DMS Beagle.
A trait that helps an organism survive in its environment is camouflage. This adaptation allows an organism to blend in with its surroundings, making it harder for predators to spot it or for prey to notice it. For example, chameleons can change their skin color to match their environment, while certain insects mimic the appearance of leaves or bark. Such traits enhance an organism's chances of survival and reproduction.
