Scientists have long observed that embryos of different species within a phylum look quite distinct at early and late developmental stages but resemble one another more during mid-embryogenesis, a ...

Behavioral lateralization, the preferential use of one side of the body and its corresponding brain hemisphere, is a pervasive aspect of vertebrate neurobiology. This phenomenon, which manifests in ...

Parthenogenesis, a form of asexual reproduction in which an egg develops in the absence of fertilisation, has traditionally been associated with invertebrates. However, recent discoveries have ...

Researchers have found that germ cells, which develop into eggs and sperm, drive sex-dependent differences in lifespan in vertebrates. Female and male germ cells increase and reduce lifespan, ...

A widely-used Living Planet Index (LPI) characterizes the average change in population sizes of vertebrates and is considered one of the main indicators of the state of the planet. Anna Toszogyova, ...

An in-depth analysis reveals that for each identified vertebrate species, there may be two others, nearly identical in appearance but genetically distinct. Scientists have long classified ...

Add Yahoo as a preferred source to see more of our stories on Google. After an ancient extinction killed about 85% of marine species, survivors in isolated refuges helped jawed vertebrates diversify ...

The coelacanth is known as a “living fossil” because its anatomy has changed little in the last 65 million years. Despite being one of the most studied fish in history, it continues to reveal new ...

Scientists found that adult bristleworm eyes grow continuously thanks to a rim of neural stem cells similar to those in vertebrate eyes. This growth is surprisingly regulated by environmental light ...

A research team led by Profs. Zhu Min, Lu Jing, and Zhu You'an from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences published two back-to-back ...
