Yuri Deigin, Co-Founder of YouthBio Therapeutics, finds it interesting that we still don’t know the genetic causes of different maturation rates between species. If we understand the genetic mechanisms for development, it will greatly inform our understanding of aging processes. There is a direct coupling between sexual maturity and total lifespan, which seems extremely relevant to aging biology. The field of aging hasn’t spent enough effort investigating developmental program stages between species in regard to aging.
