What Is Environmental Acclimation?

Environment Acclimation is a selection of traits favorable for a given environment and is the primary cause of natural breeding and speciation. Mating selections are typically based on appearance / phenotype which in turn select the genetics behind those traits / genotype. This is similar to the evolutionary process of natural selection; however it can occur rapidly because already existing traits are chosen and no new genetic material must form over time.


The habitat or environment where an individual or population lives is considered to be one of the strongest influences on breeding or genetic selection. The environmental pressures created by heat or cold, dry or wet, and rocky or fine soils all help to determine what characteristics will do best in that environment. For example, in an open environment, running fast could be an important trait for both prey and predator.


Micro-habitats further refine the traits in a population. For example, a mountain habitat would typically have a southern slope which receives more sun than the northern slope. They can also have areas of steep slopes or even vertical walls. Depending on the prevailing winds and conditions, one side may be quite moist while the other side is quite dry. Each of these conditions would favor a different characteristic.

Adaptive Radiation

The concept of adaptive radiation is an evolutionary concept in which a species enters a new environment and, through such processes as mutation and natural selection, develops into new species up to and including possessing new forms and features. Therefore, this can include both micro- and macro- evolutionary changes.

Environmental Acclimation

A term is needed which can express that small changes, such as skin or flower color, can be effected by the environment which does not allow for the formation of new genetic information. I put forward Environmental Acclimation.

Furry Animal Example

For example, a furry animal that has the genetic variability for long, medium, or short length fur is carried to several different environments and released. Within a hot climate short haired animals will do better. Similarly, in a cold environment long-haired animals will do better. In a wet environment oily-furred animals will do better because it keeps the skin dry. Over time, the genes for a specific fur type are chosen and become common while the other gene type(s) will decrease or disappear. During this process, no new genetic information was needed nor was any change in form observed. The animal population simply acclimated to the environmental pressures.

Habitats after the Flood

Presumably, the world was in much worse shape after the Flood. The environment had changed drastically and probably included new things like rain and snow as well as hot deserts and frozen areas. It probably now included mountains and tropical areas. As the animals emerged from the Ark and began migrating, they would begin acclimating to these environments. Such acclimation would be limited to what existed within the gene pool of any given population.

Acclimation after the Flood

According to a scriptural timeline, about 4,300 years have passed since the time of the flood. This probably included an ice age shortly after the period of the flood. During this time, rapid diversification would have occurred within animal kinds as they spread out and moved into new habitats. This diversification is not a sign of evolution in progress, but is instead simply the breeding out of characteristics that already exist within the animals.
