Lecture by prof. Yves Van de Peer (Department of Plant Biotechnology & Bioinformatics ) on if and how ancient stressfull conditions facilitated whole genome duplications (WGDs) in plants and animals

There are thousands of species, plants and animals, that are polyploid: they contain multiple copies of their genome. On the other hand, the long-term establishment of organisms that have undergone ancient whole genome duplications (WGDs) has been exceedingly rare. This is an interesting and fascinating paradox.
There is evidence that the majority of ancient WGDs were established at specific times in evolution, for instance during periods of environmental change, ecological upheaval, or periods of mass-extinction. This suggests that stressful environmental conditions might increase the likelihood of WGDs.

I will discuss the many examples of known WGD events and how they might have facilitated or were responsible for the evolution of major lineages of organisms such as vertebrates, fishes, flowering plants, grasses and orchids.
