Hidden within fish DNA are powerful genetic twists that may explain one of nature’s biggest mysteries: how new species form so quickly. In Lake Malawi, hundreds of cichlid fish species evolved at ...
Over millions of years, the Earth’s upper layers have performed a dance that has created mountains, volcanoes, continents, ridges and ocean trenches. Tectonic plates play a key role in this process.
ANN ARBOR—For a long time, evolutionary biologists have thought that the genetic mutations that drive the evolution of genes and proteins are largely neutral: they're neither good nor bad, but just ...
The process of evolution usually takes thousands, millions or even billions of years. But researchers have found a way to condense it into a matter of minutes using a method called 'directed evolution ...
During the course of evolution, the mammalian cranio-mandibular secondary joint—formed by the dentary condyle and the squamosal glenoid fossa, which replaced the reptilian articular–quadrate ...
Why does natural selection appear to happen slowly on long timescales and quickly on short ones? A multigenerational study of four lizard species addresses biology’s “paradox of stasis.” James Stroud ...
Computer simulations suggest that evolution itself could be evolving, depending on environmental pressures. This would mean that not only do living things change over generational time but the ...
There are few forms of the botanical world as readily identifiable as fern leaves. These often large, lacy fronds lend themselves nicely to watercolor paintings and tricep tattoos alike. Thoreau said ...
