Based on such concerns, a group of researchers sought to describe the importance of all major groups of organisms in the global wildlife trade and called for more research on neglected groups. Their ...

These organisms are not necessarily closely related. However, certain features unite them, while distinguishing them from the other major group of photosynthetic organisms: the land plants.

Small organisms are also ancient and incredibly ... Plot the size distribution for nearly any major group of animals and you will find a strikingly positive skew: most species are much closer ...

Now researchers have developed a simple DNA PCR-based lab test -- built on a more detailed genetic analysis of the main group of bacterial organisms that cause the infection -- to help clinicians ...

What Darwin was bemoaning was the lack of “transitional” fossils – those with anatomical features intermediate between two major groups of organisms. At the time, such fossils were conceived ...

The animal kingdom consists of more than 30 major body ... this tommotiid group called camenellans. Palaeontologists have thought that those shells were attached to an agile organism—crawling ...

Efforts to use regenerative medicine—which seeks to address ailments as diverse as birth defects, traumatic injury, aging, degenerative disease, and the disorganized growth of cancer—would be greatly ...

And then there's the molecular evidence, which suggests that many of the major groups of organisms that appear in the Cambrian had probably been separated for a significant amount of time in order ...

The striking differences in both species richness and morphological diversity that exist between major groups of organisms constitute a ubiquitous yet unexplained pattern in the large-scale ...

"This study demonstrates the dynamic nature of evolutionary change within major groups of organisms," said Melanie Hopkins, one of the co-authors on the study and an assistant curator in the ...

Instead, Retallack argues that that the very first landlubbers belonged to an extinct group of organisms called Ediacara, which last lived on Earth some hundred million years before the rise of ...
