A playground for evolution

The term “genome” refers to the entirety of the genetic material that is encoded in each individual cell of an organism and contains information that dictates how species-specific morphological structures are formed. For instance, the genome of a fruit fly encodes the information for developing wings, whereas a spider’s genome contains the code for it to grow spinnerets and venom glands. Thus far, a duplication of the genome has only been determined for vertebrates. Now, for the first time, an international team of scientists collaborating with the University of Göttingen has found that the genomes of spiders and scorpions similarly underwent duplication.
