Genetic accommodation, a key evolutionary mechanism, is supported by new evidence in insects. This process, including genetic assimilation, offers a plausible pathway for evolutionary change, though further research is needed.

Area of Science:

Evolutionary biology
Genetics
Developmental biology

Background:

The role of genetic assimilation and genetic accommodation in evolutionary change is debated.
Experimental evidence for these mechanisms is crucial for understanding evolutionary processes.

Purpose of the Study:

To examine experimental evidence for genetic assimilation and genetic accommodation.
To assess the plausibility of genetic accommodation as an evolutionary mechanism.

Main Methods:

Review of experimental studies on genetic assimilation in Drosophila.
Analysis of a new study on color polyphenism evolution in Manduca sexta.

Main Results:

Experiments in Drosophila provide evidence supporting genetic assimilation.

A new study demonstrates color polyphenism evolution via genetic accommodation in Manduca sexta.

Conclusions:

Genetic accommodation, encompassing assimilation, is a plausible evolutionary mechanism.
Further research is necessary to elucidate the precise role and frequency of genetic accommodation in evolution.
