Mechanical mechanisms of morphogenesis as potential substrates for evolutionary change

Area of Science:

• Cellular mechanics
• Developmental biology
• Biophysics

Background:

• The role of physical forces in cellular behaviors and morphogenesis was recognized over a century ago in experimental embryology.
• Modern molecular biology and live imaging have enabled a deeper integration of mechanical and genetic mechanisms.

Purpose of the Study:

• To review recent advances in understanding the interplay between mechanical and molecular genetic mechanisms in development.
• To explore the evolutionary pressures on both morphology and the physical forces that generate it.

Main Methods:

• Literature review of recent advances in cellular mechanics and developmental biology.
• Synthesis of findings linking mechanical and molecular genetic pathways.
• Discussion of evolutionary implications for physical mechanisms in development.

Main Results:

• Significant progress has been made in connecting cellular material properties and forces to gene activity during development.
• The field is poised to elucidate how mechanical forces contribute to morphogenesis at a molecular level.

Conclusions:

• Understanding the mechanical underpinnings of morphogenesis is crucial for a comprehensive view of development.
• Evolutionary forces may act on the physical mechanisms of development, not just the resulting structures.
