Art meets science: The Cosmopolitan Chicken Research Project

Area of Science:

• Genomics
• Animal Breeding
• Evolutionary Biology

Background:

• The Cosmopolitan Chicken Project (CCP) is an artistic initiative by Koen Vanmechelen, using chicken crossbreeding to symbolize global diversity.
• The project's scientific arm, the Cosmopolitan Chicken Research Project, investigates the impact of interbreeding on genetic diversity.

Purpose of the Study:

• To analyze the effect of systematic crossbreeding on genetic diversity in domestic chickens.
• To compare genetic diversity changes under ideal population assumptions versus realistic breeding conditions.
• To explore potential implications for understanding human genetic diversity.

Main Methods:

• Utilized state-of-the-art genomic techniques to measure genetic diversity.
• Applied two analytical approaches: one assuming large, stable populations and another reflecting the CCP's breeding experiment.
• Assessed genetic diversity across 26 purebred and crossbred chicken populations.

Main Results:

• Under ideal conditions, a steady increase in genetic diversity was observed, supporting the creation of a "Cosmopolitan Chicken Genome."
• Under CCP breeding conditions, reflecting real-world scenarios, genetic diversity fluctuated within boundaries rather than steadily increasing.
• Observed fluctuations suggest a potential evolutionary optimum for genetic diversity, possibly applicable to human populations.

Conclusions:

• Systematic crossbreeding can enhance genetic diversity, but practical limitations lead to fluctuations.
• The CCP's findings offer insights into the dynamics of genetic diversity in both animal and human populations.
• The research highlights the complex interplay between breeding strategies and the maintenance of genetic variation.
