Researchers at University of Tsukuba and their collaborators have conducted a comprehensive analysis of the olfactory ...

Figure 1: Fossils relevant to early jawed-vertebrate evolution derive from major fossil sites in North America and Europe, and increasingly China and Australia. Crown-, total- and stem-group concepts ...

Biologists have considered nearly every major taxon of animals as the key starting point for the evolution of vertebrates. We survey these ideas, many of which are no longer tenable in the light of ...

My, what small teeth they had. A newfound treasure trove of ancient fish fossils unearthed in southern China is opening a window into the earliest history of jawed vertebrates — a group that ...

A stunningly preserved, soft-bodied fish that is more than 500 million years old could be the ancestor of almost all living vertebrates. The fossilized fish, called Metaspriggina, sports ...

The sea lamprey, a 500-million-year-old animal with a sharp-toothed suction cup for a mouth, is the thing of nightmares. A new study from the Stowers Institute for Medical Research discovered that the ...

The cradle of vertebrate evolution was limited to a zone of shallow coastal waters, no more than 60 meters deep. In those waters, fish — the first vertebrates — appeared roughly 480 million years ago, ...

Those of you who took high school biology may remember the lancelet, also known as the amphioxus. Its simplified body plan is notable for containing a number of features that it shares in common with ...

In the aftermath of historically severe wildfires in 2020, a study of Cascade Range watersheds found that stream vertebrates ...

Vertebrates are animals that have a spine (backbone) inside their body. Other organisms, like spiders and snails, that don’t have a backbone are called invertebrates. Fran: Here at the farm there are ...
