A new study analyzing the origins of the adipose fin, thought by some to be vestigial, finds that these fins arose repeatedly and independently in multiple species -- a striking example of convergent ...

It turns out humans aren’t the only ones checking out what their neighbors are doing when looking for ideas on how to make life easier. All species adapt and evolve in a variety of ways. In fact, ...

Researchers identified the proteins of a CO2-fixing organelle, namely, 'pyrenoid,' in the marine algal group Chlorarachniophyta and revealed various pyrenoid-associated proteins among algal groups, ...

In the frigid waters of the ocean surrounding Antarctica, fish have a special trait which allows them to survive the big chill. As scientists discovered in the 1960s, the fish have adapted by evolving ...

An unprecedented amount of genomic sequence data is accumulating in real-time during the COVID-19 pandemic. Over 1.2 million sequences of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) ...

Similar phenotypic traits such as anatomical structures and physiological functions often evolve independently in different organisms. Nonetheless, the evolutionary paths leading to these convergent ...

A new study reveals the surprisingly convergent evolution in the inner ear of mammals. An international research team led by Nicole Grunstra from the University of Vienna and Anne Le Maître from the ...

Researchers have discovered a new carnivorous water rat on the island of Sulawesi that’s so unique it represents an entirely new genus. They believe many more rodent species await discovery in this ...

In a series of three extraordinary papers published between 2004 and 2013, Max D. Cooper and colleagues discovered a new type of adaptive immunity in jawless vertebrates. This revolutionary discovery ...
