A study of more than 60,000 specimens of snakes and lizards worldwide reveals that snakes stand out alone in the evolution of reptiles. The team of scientists d

<p>More than 100 million years ago, the ancestors of the first snakes were small lizards that lived alongside other small, nondescript lizards in the shadow of the dinosaurs.</p> <p>&nbsp;</p> <p>&nbsp;</p>

Over 100 million years ago, before snake evolution began, the world was a vastly different place, teeming with alien-like life forms.

Since first appearing during the age of dinosaurs, snakes have authored an evolutionary success story - slithering into almost every habitat on Earth, from oceans to tree tops. Scientists generated a comprehensive evolutionary tree of snakes and lizards aided by genomic data spanning roughly 1,000 species, while reviewing the fossil record and compiling data on snake diet, skull anatomy, reproductive biology and geographical range. They found that snakes experienced a burst of innovation early i

Since first appearing during the age of dinosaurs, snakes have authored an evolutionary success story - slithering into almost every habitat on Earth, from oceans to tree tops. Scientists generated a comprehensive evolutionary tree of snakes and lizards aided by genomic data spanning roughly 1,000 species, while reviewing the fossil record and compiling data on snake diet, skull anatomy, reproductive biology and geographical range. They found that snakes experienced a burst of innovation early in their history and have evolved at a rate perhaps three to five times faster than their lizard co...
