Scientists have investigated lamprey embryos using cutting-edge microscopic techniques to reveal interesting insights about vertebrate head evolution, clarifying an unresolved mystery in basic science ...

Jawless, bloodsucking fish could help us understand how humans and all other vertebrates evolved, scientists say. Turns out, lampreys — notable for their lack of jaw and generally terrifying ...

Jawed vertebrates, or gnathostomes, underwent a transformative diversification marked by paired jaws, mineralised skeletons and advanced sensory systems. Phylogenetic research integrates fossil ...

A feeding method of the extinct jawless heterostracans, among the oldest of vertebrates, has been examined and dismissed by scientists, using fresh techniques. A feeding method of the extinct jawless ...

In DNA, retrotransposons can move around and insert themselves into other parts of genomes with a kind of copy and paste mechanism. Most have lost this ability in humans, but they still make up a ...

During the course of evolution, the mammalian cranio-mandibular secondary joint—formed by the dentary condyle and the squamosal glenoid fossa, which replaced the reptilian articular–quadrate ...

As our species (Homo sapiens) evolved and spread across the globe, they were contemporary with several other hominins. These include the best-known of our evolutionary cousins, the Neanderthals, but ...

A harlequin poison dart frog (Oophaga sylvatica) is pictured at the Tesoros de Colombia (Treasures of Colombia) sustainable farm in Nocaima, Cundinamarca department, Colombia, on July 9, 2024.

The water-to-land transition stands as one of the most significant events in vertebrate evolution, giving rise to the two major groups of living land vertebrates-amniotes and lissamphibians-which ...
