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 ...

A new exhibit at Butterfly Pavilion offers insight into the evolution of its invertebrate residents, as well as humans and other vertebrates. For millions of years, Earth was home to single-celled ...

Invertebrates such as spiders and centipedes are underappreciated kings of the jungle, eating a surprising amount of vertebrates in the Amazon, a new study says. Biologists recently documented 15 ...

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.

The film discusses the characteristics and classifications of chordates, a group of animals that includes vertebrates and some simpler forms. Key features of chordates include a pharyngeal breathing ...

Our earliest invertebrate ancestors did not have brains. Yet, over hundreds of millions of years, we and other vertebrates have developed amazingly complicated mental machinery. "It must have ...

Scientists report finding some of the genetic processes that regulate vertebrate brain development in the acorn worm, a brainless, burrowing marine invertebrate. The origin of the exquisitely complex ...

Genetic material once dismissed as mere "junk" may in fact be responsible to the evolution of simple invertebrates into more complex organisms sporting backbones, according to a new study. Tiny ...

What are ammonites, and how did they come to rule the prehistoric seas? What are ammonites, and how did they come to rule the prehistoric seas? Invertebrates are animals without a backbone or bony ...
