SOMMARIO
- Gli Animali (o Metazoi) sono organismi eucarioti, eterotrofii, pluricellulari e mobili durante almeno uno stadio della loro vita. Si riconoscono circa 1,5 milioni di specie note viventi.
- Il loro processo evolutivo è in atto da oltre 500 milioni di anni.
- Sono classificati in base ai differenti piani strutturali corporei che li caratterizzano.

- Gene mutation linked to obesity: Mice gain weight even when fed normal amounts of foodResearchers have identified a genetic cause of severe obesity that, though rare, raises new questions about weight gain and energy use in the general obese population. The research involved genetic surveys of several groups of obese humans and experiments in mice. […]
- Best romantic singers are male batsMale bats appear to be the sexy singers of the animal world: they have learned to vocalize in a specific way to attract females, but once they have their attention, they change their tune – literally. They then produce a more creative array of sounds to entertain and keep the females interested. […]
- Microbes can influence evolution of their hostsContrary to current scientific understanding, it appears that our microbial companions play an important role in their hosts' evolution. A new study provides the first direct evidence that these microbes can contribute to the origin of new species by reducing the viability of hybrids produced between males and females of different species. […]
- Evolutionary changes could aid fisheriesSustainable fishing practices could lead to larger fishing yields in the long run, according to a new study that models in detail how ecology and evolution affect the economics of fishing. […]
- Endoplasmic reticulum: Scientists image 'parking garage' helix structure in protein-making factoryThe endoplasmic reticulum is the protein-making factory within cells consisting of tightly stacked sheets of membrane studded with the molecules that make proteins. Now, researchers have refined a new microscopy imaging method to visualize exactly how the ER sheets are stacked, revealing that the 3D structure of the sheets resembles a parking garage. This st […]
