The distribution of live-bearing among living vertebrates strongly suggests that internally fertilizing live-bearers are unlikely to give rise to externally fertilizing spawners, so we would not ...

One possibility is that intelligence in vertebrates—animals with backbones, including mammals and birds—evolved once. In that case, both groups would have inherited the complex neural pathways ...

There's a 'new' fossil discovery at ROM! Jean-Bernard Caron, Richard M. Ivey Curator of Invertebrate Palaeontology, shows us a new moth-like predator from the 506-million-year-old Burgess Shale of ...

The unique features of Mosura fentoni astounded paleontologists. Paleontologists have discovered that a three-eyed sea moth predator lived on Earth half a billion years ago with evidence found in ...

Ivey Curator of Invertebrate Paleontology at the Royal Ontario Museum in Toronto, in a statement. No animal living today quite looks like Mosura fentoni, Moysiuk said, although it had jointed ...

“We are particularly concerned about invertebrate animals in the ocean, which absorbs most of the heat from climate change,” Ripple said. “Those animals are increasingly vulnerable because ...

Only animals that evolved to live solely on land ever developed claws. The earliest vertebrates -- fish and amphibians — never developed hard nails and remained dependent on watery environments ...

Insects and other invertebrates are an essential component of any wildlife garden. Very valuable in their own right, many also provide food for insectivorous birds. You can attract invertebrates to ...

An insect that harvests and modifies plant resin to snare its prey adds to a growing body of evidence that suggests we may be underestimating the cunning of invertebrate animals. The assassin bug ...

After a brief rain 350 million years ago, a reptile pressed its claws into the ground. Its tracks now show the oldest-known vertebrate to take on dry land. It also significantly pushes back the date ...

The study of the physiology and ecology of animals that don't have backbones, ranging from worms to sea stars, and of parasites, which can often provide insights into complex ecosystems. (Sea star ...
