An international scientific team including more than 40 authors from seven different countries, led by a researcher at the University of Malaga Juan Pascual Anaya, has managed to sequence the first ...

Scientists once thought that humans must have two million genes to account for all our complexity. But since sequencing the human genome, we've learned humans only have about 19,000 to 25,000 genes - ...

The number of vertebrate species inhabiting the different regions of the world is highly variable, as is the proportion of threatened species. Some regions, such as the tropics, have more threatened ...

New CU Boulder-led research finds that the traits that make vertebrates distinct from invertebrates were made possible by the emergence of a new set of genes 500 million years ago, documenting an ...

Analysis of a 458-million-year-old fossil fish reveals anatomical insights about the vertebrate skull and how skull organization evolved from that of ancestral early vertebrates to that of jawed ...

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 study of fossilized lampreys dating from more than 300 million years ago is challenging a long-held theory about the evolutionary origin of vertebrates. These ancient, jawless, eel-like fishes arose ...

A feeding method of the extinct jawless heterostracans, among the oldest of vertebrates, has been examined and dismissed by scientists, using fresh techniques. A feeding method of the extinct jawless ...

Humans tend to put our own intelligence on a pedestal. Our brains can do math, employ logic, explore abstractions and think critically. But we can’t claim a monopoly on thought. Among a variety of ...

A new study out of the University of Chicago, the Canadian Museum of Nature and the Albany Museum challenges a long-held hypothesis that the larvae of modern lampreys are a holdover from the distant ...
