Cricket's finicky mating behavior boosts biodiversity

... the cricket's rate of speciation on the Laupala's phylogeny and on the age of the islands in the Hawaiian archipelago. The youngest island, Hawaii, was formed less than 500,000 years ago. ...

Ancient anthropoid origins discovered in Africa

...lationships. If down the road we find out that our phylogeny was wrong, Biretia could end up being very significant for our understanding of the origin of anthropoid activity patterns." According to Simons, analyses of the teeth of the two species clearly place them as members of a group called parapithecoids...

The evolution of food plants: Genetic control of grass flower architecture

...mendous diversity in inflorescence morphology, the phylogeny is well understood and many species are genetically transformable so hypotheses can be tested. Maize in particular is an excellent model system for studying selection as it was domesticated from its wild ancestor teosinte a mere 10,000 years ago. Bec...

Hantavirus found in African wood mouse

...en. "According to the co-evolution hypothesis, the phylogeny (evolutionary history) of viruses that are restricted to a host species mirrors the phylogeny of their respective hosts," he explained. "So the discovery of an African hantavirus will significan...

Sociality of sweat bees evolved simultaneously during climate change

...the fossils allow the researchers to represent the phylogeny in terms of a timeline in millions of years. In 2002 and 2004, Danforth showed that the social evolution of the various species of halictid bees arose multiple times independently. The study on the timing of that social evolution, however, began as ...

Two studies on bee evolution reveal surprises

...nd morphological study to date on bee family-level phylogeny -- the evolutionary development and diversification of a species. Their goal was to examine the early evolutionary pattern of bees and how their evolution relates to the evolution of flowering plants. Flowering plants are among the most diverse organ...
