Constrained evolution is ecological adaptation

translocated chromosome

See also: Unconstrained evolutionary innovability Ideas that evolution is not constrained can be compared to experimental evidence of biophysically constrained ecological adaptations. The most recent relevant open access published work from the Jakobsson lab is: TRIM28 Represses Transcription of Endogenous…

Prehistoric genomes reveal the genetic foundation and cost of horse domestication Reported as: Reshaping the horse through millennia Excerpt: “Domestication is generally associated with repeated demographic crashes. Yet, mutations that negatively impact genes are not eliminated by selection and can even…
