Shark bone mineralization shown to be adaptive trait
Original: Quantitative imaging supports that endoskeletal mineralization in sharks is an adaptive trait
New research published in Nature presents quantitative imaging evidence that mineralization of the shark endoskeleton is an adaptive trait rather than an evolutionary remnant. The study suggests sharks, despite lacking true bone, retain and regulate skeletal mineralization because it benefits their biology, offering fresh insight into vertebrate skeletal evolution.
Why now: A newly published Nature study challenges the view that shark skeletal mineralization is vestigial, prompting interest among biologists.
