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 ...

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 ...

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 ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

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 ...

WOODS HOLE, Mass. - Sharks, skates, and rays are oddities among the fish: They have appendages growing out of the gill arch, a small cradle of bones that supports the gills. This anatomical ...

In 1878, German anatomist Karl Gegenbaur proposed a theory that fish fins and human limbs evolved from a structure that resembles gill arches, a collection of bony "loops" in fish that support the ...

Neural crest cells -- embryonic pluripotent cells within the facial primordium -- may be necessary for forming proper animal facial structures. Researchers have produced neural crest cell-rich ...

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, ...
