In science, this sometimes called the survival of the fittest or natural selection.If all individuals in a species are not exactly clones of each other but have small variations in the genes (traits), some will do better when the environment changes. These traits will be 'favored' over other traits.
As all the cloned individuals are identical they have exactly the same strengths and weaknesses. If the environment changes rapidly in a way that makes it harder for them to survive then most or even all individuals may be eliminated before any evolved better ways to survive in the changed environment. In species that have other means of reproduction available their populations have greater diversity in strength and weaknesses, so there is a greater chance that some individuals will already be able to better survive in the newly changed environment. Those individuals will pass on their traits to the next generation.
1. There is variation in individuals within a species 2. Variation ensures that individuals that are better suited to their environment will survive. 3. Traits that assist individuals in survival and allow them to reprduce gradually spread throughout population. 4. Individuals produce more offspring than the local resources can support.
In bio, adaptation usually refers to an evolutionary change an organism has made to better suit its environment. This change is a process and usually takes thousands of years. Evolutionary adaptation is not to be confused with acclimation, which is when an organism simply gets used to its environment during its lifetime and makes no evolutionary changes.
Evolution occurs via natural selection when certain traits become more favorable in a population over time. This is typically due to the environment or natural selection pressures in the population. Natural selection works by favoring individuals with traits that are better suited to the environment while those with less favorable traits may die off or be less likely to reproduce. Over time these favored traits become more common while unfavorable traits become less common. This process eventually leads to evolution as the population changes to adapt to its environment. The three main components of natural selection are: Variation: Individuals within a population have different traits Inheritance: Traits are passed from generation to generation Differential Reproduction: Traits that are more favorable are more likely to be passed onNatural selection is an ongoing process as the environment is constantly changing and influencing the traits of the population. It is important to note that natural selection is not a directed process and does not necessarily lead to a specific outcome. The result of natural selection is determined by the environment and the traits that are favored in the population.
Natural Selection
Natural selection a theory by Charles Darwin
The process by which individuals that have favorable variations and are better adapted to their environment survive and reproduce more successfully than less well adapted individuals is called natural selection. This is part of Darwin's theory.

no organisms adapt to the environment to help them survive

Natural Selection is a process which individuals are better adapted to their enviorment are more likely to survive and reproduce. Say there are turtles barely hatching and there are hungry seagul waiting to be fed, the fastest ones will make it to the water safely while the slow ones are being eaten. so eventually all the turtles in the sea will become faster to get away from predators. hopefully that answered your question.
It means - usually the strongest, fastest, or best climber will survive over similar animals that are weaker. If an animal is fast, strong or a good climber - it has a better chance of evading predators.
Leave more offspring then those less suited for the environment.
