The Ancient Origins of Live Birth: Rewriting the Story of Reproduction The discovery of a 236 million year old fossil, Chiniquodon theotonicus, has sent shockwaves through the scientific community.
This ancient creature's ability to give birth, rather than lay eggs like its reptilian cousins, marks a significant milestone in our understanding of mammalian evolution.
The finding pushes back the timeline for the emergence of live birth by up to 95 million years, forcing scientists to reevaluate their assumptions about the origins of this trait.
