Phenotypic Evolution With and Beyond Genome Evolution

Area of Science:

• Evolutionary biology
• Developmental biology
• Genetics

Background:

• DNA is not the sole determinant of phenotypes.
• Phenotype construction involves intricate DNA-environment-organism interactions.
• Understanding these interactions is crucial for evolutionary biology.

Purpose of the Study:

• To review the process of phenotype construction.
• To examine interactions between DNA, organism, and environment across evolutionary timescales.
• To integrate recent findings on phenotypic variation and evolution.

Main Methods:

• Literature review integrating recent results and examples.
• Analysis of phenotype construction at individual and population levels.
• Examination of genetic and environmental influences on variation and inheritance.

Main Results:

• DNA acts as a template and is involved in feedback loops during phenotype construction.
• Phenotypic variation arises from joint stochastic, environmental, genetic, and parental sources.
• Genotype and environment exhibit distinct properties in variation, transmission, and feedback across generations.

Conclusions:

• Phenotype construction is a dynamic process influenced by multiple interacting factors.
• Evolutionary processes are shaped by the interplay of DNA, organism, and environment.
• This review adds depth to the standard evolutionary synthesis by emphasizing these interactions.
