Evolution of new species requires few genetic changes

Only a few genetic changes are needed to spur the evolution of new species—even if the original populations are still in contact and exchanging genes. Once started, however, evolutionary divergence evolves rapidly, ultimately ...

The endemic species of remarkable Fulgoromorpha from Iran

In terms of biodiversity richness, Iran is considered as an extremely complex area with wide ranges in the extremes of altitude, climate and temperature. The high biodiversity of the Iranian fauna is also the result of its ...

New research constructs ant family tree

Anyone who has spent time in the tropics knows that the diversity of species found there is astounding and the abundance and diversity of ants, in particular, is unparalleled. Scientists have grappled for centuries to understand ...

What can 'ring species' teach us about evolution?

Ten thousand years ago, at the end of the last ice age, a species of greenish warblers lived in a forest south of the Tibetan Plateau. As the ice receded, the forest grew to form a ring around the plateau—and so did the ...

More new species in geologically dynamic region

Mountain formation stimulates increased biodiversity. This is what Carina Hoorn of the University of Amsterdam (UvA) and colleagues from the Senckenberg (Germany) and Gothenburg Botanical Garden (Sweden) propose in a Correspondence ...

Climate change makes more shrew species, 70 genetic varieties

Anyone who went outside this summer felt the effects of climate change. Now the Eurasian shrew, Sorex araneus, can say the same. A new study by P. David Polly of Indiana University found that climate change caused shrews ...
