In a world-first observation, scientists have witnessed evolution in action with the Australian three-toed skink (Saiphos equalis).
This unique lizard species is "bimodally reproductive," meaning some populations lay eggs while others give birth to live young.
Remarkably, researchers documented a single female laying three eggs and then giving birth to a live baby from the same pregnancy.
This rare versatility suggests the species may be in the middle of an evolutionary transition between different birthing methods.
Being able to switch could allow these lizards to better survive changing environmental conditions.
