Analysis of wing variation within and between fly species reveals an unexpectedly slow evolutionary rate. Variations due to mutation and interspecific differences are similar, perhaps as a result of ...

Basic knowledge about the rate and range of mutation is central to our understanding of numerous evolutionary processes that include maintaining sexual reproduction and rates of molecular evolution.

"In trees, somatic mutations can be transmitted to seeds, resulting in rich genetic variations within subsequent generations," states one of the author Masahiro Kasahara, Associate Professor in the ...
