This clade, in turn, shares an ancestor with a group called Lepidosauria, which gave rise to all modern lizards, snakes and the tuatara. That shared ancestor was a creature called a sauropsid that ...

Researchers who have studied genetic evidence of iguanas suggest the ancient reptiles traveled nearly 5,000 miles from North ...

The trek—from the North American desert to Fiji—now represents the longest known migration of any terrestrial animal.

Figure 3 illustrates this idea using a clade that contains four lizard species ... of how recently these species last shared a common ancestor. One profound implication of this way of thinking ...

The researchers conducted a comprehensive genetic analysis, examining over 4,000 genes from 200 iguanian specimens.

The iguanas' 8,000-kilometer trip — one-fifth of the Earth’s circumference — is the longest made by a flightless land vertebrate.

Native to Europe, common wall lizards are growing bigger, faster, and more resilient in Ohio. Scientists say the city itself may be driving their evolution. A Lazarus lizard suns itself on a warm ...
