[D.K. Beliaev's evolutionary concept--ten years later]

Area of Science:

• Evolutionary biology
• Genetics
• Developmental biology

Background:

• This study examines D.K. Belyaev's evolutionary concept, integrating recent domestication research with modern evolutionary theories.
• It explores the role of genetic expression regulation in evolution, particularly under extreme conditions.

Discussion:

• The research details neuroendocrine system changes during long-term domestication.
• It discusses the morphogenetic influence of hormones and neurotransmitters on evolutionary processes.

Key Insights:

• Selection impacts developmental process rates, leading to heterochronies.
• These heterochronies are crucial for understanding the morphogenetic outcomes of behavioral selection.

Outlook:

• Further research can elucidate the intricate relationship between genetic regulation, neuroendocrinology, and behavioral evolution.
• This work provides a framework for investigating evolutionary adaptations in various contexts.
