Because of the environmental difference, the local fish populations will have developed different genetic adaptations.

Other animals required "genetic adaptation" but survived in some form or another.

Certainly if a race did not die off except when killed that would slow its evolution and genetic adaptation to an environment.

During the process, the environment does not change in favour of one species and the genetic adaptation is sufficiently slow.

Here, learned behavior that improves fitness also prevents genetic adaptation.

The next xenobiologist will probably work with standard genetic adaptations and won't follow this up.

"Chains is home to all nulls, and other genetic adaptations.

"The plants are also genetic adaptations," Denise said, enjoying his discomfort.

Researchers believe that by studying the genetic adaptations of these organisms, we can learn more about how biology works.

What remained was "micro-evolution," which refers to genetic adaptation and natural selection within a species.

"The wisdom of the genes" is how he characterizes the accumulated facility of genetic adaptation.

He wants to evolve genetic adaptations that will allow organisms to survive the stress of working close to singular- ities.

This is a genetic adaptation and plants kept permanently wet in cultivation also lose their pitchers in mid summer.

The DNA test shows that the dragon has a genetic adaptation in the gene responsible for creating limbs.

But odds are we have a bipedal creature of basic form, like ourselves, with genetic adaptation to local stellar radiation and planetary conditions."

Therefore, phenotypic plasticity allows S. stercoraria to adjust development according to unpredictable ecological situations without genetic adaptation.

It has been speculated that a portion of the Sherpas' climbing ability is the result of a genetic adaptation to living in high altitudes.

Most of this adaptability depends upon cultural invention but, in a limited fashion, Homo also seems to undergo quite rapid genetic adaptation to specialized local conditions.

Evolutionary biologists use the term convergence to describe this phenomenon, not uncommon, of two unrelated species responding to similar environmental conditions by developing similar genetic adaptations.

Centuries of genetic adaptation and a lifetime of physical conditioning were implied in the force of his leap, and he made it with energy to spare.

The idea of real-time genetic adaptation to environment-T'Lyrey's fallacy was disproved two hundred fifty years before the Exile!"

However, intermixing two different populations may give rise to unfit polygenic traits in outbreeding depression, yielding offspring which lack the genetic adaptations to specific environmental conditions.

The downside to this is that, when re-released, the species may lack the genetic adaptations and mutations which would allow it to thrive in its ever-changing natural habitat.

The genetic adaptation to cold is still carried by many Northern Europeans, East Asians and American Indians, most of whose ancestors once lived in Siberia.

Physiological and metabolic maladaptations result from the suboptimal genetic adaptations to the contemporary human diet, which in turn contribute to many of the so-called diseases of civilization.
