A new study reports blebbing motility — a form of cell crawling — in the closest living relative of animals, suggesting that the unicellular ancestors of animals could crawl.doi:10.1016/j.cub.2021.02.012Katrina B. VelleLillian K. Fritz-Laylin...
In one of the closest living relatives of animals, the choanoflagellateSalpingoeca rosetta, we find that rosette colony development is induced by the prey bacteriumAlgoriphagus machipongonensisand its close relatives in the Bacteroidetes phylum. Here we show that a rosette inducing factor (RIF-1) ...
It has long been clear that dogs evolved from grey wolves, but no living wolves are particularly closely related. So the prevailing hypothesis is thatdogs evolved from a now-extinct group of wolves. But which ones and where? Advertisement The Japanese wolf (Canis lupus hodophilax) w...
Traditionally, cephalochordates are considered as the closest living relatives of vertebrates, with tunicates representing the earliest chordate lineage. This view is mainly justified by overall morphological similarities and an apparently increased complexity in cephalochordates and vertebrates relative to ...

Blood sugar drops after four hours of going without food, causing a decrease(减少) in energy. Eating usually fixes this within 20 to 30 minutes, but don't suppose that eating more will cause a faster increase in energy. When you eat has as much of an effect on your mood as what you...
diversity in the living things that can occupy a region. The climates of the higher latitudes are generally less favorable for the accumulation of large quantities of biomass; hence, the structure of vegetation is simpler and the animal diversity is consequently lower....

An area of grassland vegetation with very simple structure, for example, has a very different microclimate at the ground level from that experienced in the upper canopy. Wind speeds are lower, temperatures are lower during the day (but warmer at night), and the relative humidity is much ...
