A recent paper provides an updated perspective on the evolutionary history of chelicerates—a diverse and ecologically ...

Losing Opens Up New Possibilities for Subsequent Gains Evolution is traditionally associated with increasing complexity and ...

Deletions and duplications of single-base pairs typically arise during homologous recombination and cause diseases. But what happens when a mutation occurs over multiple genes? Deletions involve ...

Adding to the list of issues that can occur with CRISPR, a team of researchers now reports a high frequency of unwanted duplications while engineering genetic insertions in mice. Worryingly to the ...

Using the “less, but more” model, a study by the University of Barcelona identifies how massive gene losses followed by extensive gene duplications can generate evolutionary adaptations in species.

The human genome can have some quirky features, like copy number variation. When this happens, an individual carries, or loses bits of DNA, which ... | Genetics And Genomics ...
