Evolutionary process behind live birth in lizards uncovered
Researchers from the University of Glasgow have discovered that live birth in Eurasian common lizards evolved through the gradual accumulation of small genetic changes rather than a single evolutionary leap. This study provides new insights into how complex reproductive strategies develop across various vertebrate lineages.

The new research is the first to reveal the evolutionary process behind this important biological change and offers a unique insight into how other species—including mammals—may have evolved to give birth to live young millions of years ago.
