How Do Complex Traits Evolve?

Hypothesis
Do novel complex traits evolve when pre-existent complex developmental networks are recruited into new places in the body?
Conclusion
The study proposes that complex traits may evolve through the co-option of existing gene networks rather than through gradual, gene-by-gene changes.
Supporting Evidence
- The study discusses how complex traits like wings and horns have evolved in insects.
- It highlights the importance of understanding gene network co-option in the evolution of new traits.
- The authors suggest that existing gene networks can be repurposed for new functions in different developmental contexts.
Takeaway
This study looks at how new traits in animals might come from using old genes in new ways instead of building new traits from scratch.
Methodology
The authors propose an empirical test to distinguish between gene network co-option and de novo network evolution by examining cis-regulatory elements in gene networks.
Limitations
The study relies on existing data and theoretical frameworks, and empirical testing of the proposed concepts is still needed.
