muokkautuminen

Muokkautuminen, also known as adaptation, is a biological process by which an organism or a population changes over time in response to changes in its environment. This process can occur at various levels, from the individual organism to the entire species. Adaptation is a key mechanism in evolution, allowing organisms to survive and reproduce in changing conditions.

There are two main types of adaptation: phenotypic and genetic. Phenotypic adaptation refers to changes in an organism's physical or behavioral traits that occur during its lifetime in response to environmental changes. For example, a polar bear's thick fur and small surface area to volume ratio help it conserve heat in cold environments. Genetic adaptation, on the other hand, involves changes in an organism's genes that are passed down to future generations. This can occur through natural selection, where individuals with advantageous traits are more likely to survive and reproduce.

Adaptation can be rapid or slow, depending on the nature of the environmental change and the organism's ability to respond. For instance, some species can adapt to new environments quickly through phenotypic plasticity, while others may require genetic changes over many generations. Adaptation is crucial for the survival and long-term success of species in a constantly changing world.
