Evolving Lizards
Not more then 4 decades (or as Lincoln would say, twoscores and six years ago) since the introduction of Italian wall lizards (?) into an island,
the lizards have undergone massive change for the 36 years there, which is a very very short timespan. The lizards showed significant changes in the structure of their head, tail, mouth and digestive tract, new structures not present in the earlier lizards grew out of stomach walls, and new ways of digesting food materialised.
Of course if you're Siang Ying and prefer larger lizards, the New York Time have
this article on the relationship between T-rex and birds.
