Non-model systems in mammalian forelimb evo-devo.

Area of Science:

• Evolutionary developmental biology
• Comparative anatomy
• Mammalian genetics

Background:

• Mammal forelimbs exhibit significant diversity in form and function.
• The study of limb development has largely focused on mouse models.
• This focus overlooks the vast evolutionary variation across mammals.

Purpose of the Study:

• To emphasize the crucial role of non-model systems in mammalian limb evolutionary developmental biology (evo-devo).
• To highlight emerging model organisms and their potential for future research.
• To synthesize recent findings and identify future research questions in mammal limb evo-devo.

Main Methods:

• Literature review synthesizing key recent works in mammal limb evo-devo.
• Discussion of gene networks influencing limb evolution.
• Exploration of functional analyses relevant to developmental studies.

Main Results:

• Non-model systems are essential for understanding the full spectrum of mammal limb diversity.
• Emerging models offer new avenues for studying limb development and evolution.
• Gene networks and functional analyses provide foundational insights.

Conclusions:

• Integrating diverse mammal systems is critical for advancing limb evo-devo research.
• Future studies should leverage non-model organisms to explore developmental patterning and variation.
• This field offers rich opportunities for understanding evolutionary processes shaping mammalian limbs.
