About 400 million years ago a group of fish began exploring land and evolved into tetrapods – today's amphibians, reptiles, birds, and mammals. But just how these ancient fish used their fishy bodies and fins in a terrestrial environment and what evolutionary processes were at play remain scientific mysteries.
Despite having retained their basic "sharkiness" for millions of years, modern sharks have less to tell us about the early evolution of jawed vertebrates—including humans—than was previously thought.
Researchers from the University of Valencia and the Natural History Museum of Berlin have studied the fossilized remains of scales and bones found in Teruel and the south of Zaragoza, ascertaining that they belong to a new fish species called Machaeracanthus goujeti that lived in that area of the peninsula during the Devonian period.
The evolutionary path from the bone structure of the fish to the complex, weight-bearing hips of walking animals was a much simpler process than previously thought, according to a new study.
Using high-energy X-rays and a new data extraction protocol, an international consortium of scientists have for the first time rendered a 3D model of a prehistoric tetrapod backbone.
Here's an anatomical packing list for making that historic trip from water to land circa 370 million years ago
A small fish crawling on stumpy limbs from a shrinking desert pond is an icon of can-do spirit, emblematic of a leading theory for the evolutionary transition between fish and amphibians.
Researchers have revealed that the African lungfish can use its thin pelvic limbs to propel itself forward.
A study into the muscle development of several different fish has given insights into the genetic leap that set the scene for the evolution of hind legs in terrestrial animals.
More than 99 per cent of modern vertebrates (animals with a backbone, including humans) have jaws, yet 420 million years ago, jawless, toothless armour-plated fishes dominated the seas, lakes, and rivers.
