Kyoto, Japan -- Mother Nature is an artist, but her craft of creating animal faces requires more than a paintbrush and palette. Such highly complex shapes originate from their respective transient ...

There's a weird genetic link between human limbs and the gills of cartilaginous sea beasts. How are the two related? Michelle Starr is CNET's science editor, and she hopes to get you as enthralled ...

WOODS HOLE, Mass., April 19 (UPI) --New genetic evidence suggests the evolutionary origins of human limbs lie in the gill arches of sharks, skates and rays. Gill arches are the collection of looped ...

Branchial anomalies in children encompass a spectrum of congenital malformations that derive from incomplete involution or abnormal development of the branchial apparatus. Embryologically, the ...

The paired limbs of humans, and before that the paired fins of fish, evolved from the transformation of gill arches in early fish, scientists say, presenting genetic evidence for this theory. Sharks, ...

Sharks, skates and rays are oddities among fish: They have appendages growing out of the gill arches, small cradles of bones that supports the gills. This anatomical peculiarity has led to the ...

Scientists believe human limbs evolved from the gills of sharks - thanks to a gene named after Sonic the Hedgehog. The discovery comes from analysis of skate, a cartilaginous fish which has much in ...

Filter-feeding fish accomplish a feat that human technologies cannot: species including goldfish, menhaden and basking sharks filter tiny algal cells or shrimp-like prey from huge volumes of water ...
