Answering evolutionary questions: A guide for mechanistic biologists

Area of Science:

• Integrative biology
• Molecular biology
• Evolutionary biology

Background:

• Molecular and evolutionary biology employ distinct questions and methods.
• Unifying these fields presents challenges but offers significant potential for discovery.
• Mechanistic biologists often lack evolutionary perspectives in their hypotheses.

Purpose of the Study:

• To provide a structured approach for mechanistic biologists to formulate evolutionarily relevant hypotheses.
• To highlight the importance of rigorous null hypotheses in biological research.
• To advocate for the integration of mathematical modeling and quantitative approaches in biology.

Main Methods:

• A question-and-answer format is used to guide biologists.
• Emphasis is placed on constructing well-defined null hypotheses.
• Examples from aging, protein structure, and speciation illustrate the approach.

Main Results:

• The proposed framework facilitates the development of evolutionarily sound hypotheses.
• Carefully constructed null hypotheses are crucial for robust scientific inquiry.
• Mathematical modeling enhances the clarity and testability of biological assumptions.

Conclusions:

• Bridging molecular and evolutionary biology yields deeper insights.
• Mechanistic biologists benefit from adopting evolutionary perspectives and quantitative methods.
• Collaboration between different biological disciplines, particularly through mathematics, is essential for scientific advancement.
