Researchers have elucidated the evolutionary origins of placodes and neural crests, which are defining features of vertebrates, through lineage tracing and genetic analysis in Ciona intestinalis, a ...

Gathering vision data for hundreds of vertebrates and invertebrates, biologists have deepened scientists' understanding of animal vision, including the colors they see. The researchers determined that ...

Invertebrates are dominant species in primary tropical rainforests, where their abundance and diversity contributes to the functioning and resilience of these globally important ecosystems. However, ...

Dolphins might come to mind when it comes to smart animals; cephalopods probably don't. But this experiment found they passed ...

The design of a protected areas network that contains or represents as many species as possible (maximum complementarity of areas) is a first step toward in situ conservation of species biodiversity.

We took the proportional extinction rates of Australian vertebrates and plants and extrapolated this to the number of Australian invertebrates. Separately, we also extrapolated the proportion of ...

Go back far enough in our history–maybe about 650 million years–and you come to a time when our ancestors were still invertebrates. That is, they had no skulls, teeth, or other bones. They didn’t even ...
