If you want to see concrete evidence of evolution, look no further than your hand or your foot. Five fingers, five toes. There's nothing magical about the number, yet five digits at the end of their ...
Researchers report a unique skeletal structure in the fins of a tetrapod-like fossil fish. Living four-limbed vertebrates, or tetrapods, exhibit a common skeletal pattern in the proximal part of their ...
The skulls of tetrapods had fewer bones than extinct and living fish, limiting their evolution for millions of years, according to a latest study. The skulls of tetrapods had fewer bones than extinct ...
New research on the fin development of the Australian lungfis elucidates how fins evolved into limbs with hands with digits. The main finding is that in lungfish a primitive hand is already present, ...
Fins and limbs and fins into limbs : the historical context, 1840-1940 / Peter J. Bowler -- Skeletal changes in the transition from fins to limbs / Michael I. Coates and Marcello Ruta -- A historical ...
"The loss of actinotrichia may have been conducive to ancestral, primitive tetrapods having limbs resembling cases of polydactyly," said Akimenko. The researchers are now looking for alternative ...
In a paper published in Nature Genetics, scientists reveal the genome assembly of the bowfin (Amia calva)—a bony fish endemic to eastern North America that is the sole surviving member of a once large ...
University of Kentucky College of Medicine researchers were part of a new study that gives insight into how limb development evolved in vertebrates. The findings, published in Current Biology Oct. 4, ...
Earliest land animals had fewer skull bones than fish – restricting their evolution, scientists find
The skulls of tetrapods had fewer bones than extinct and living fish, limiting their evolution for millions of years, according to a latest study. By analysing fossil skulls of animals across the ...
