Mobile DNA Sequences Could Be The Cause Of Chromosomal Mutations During The Evolution Of Species

Summary:
Researchers from the Department of Genetics and Microbiology at the Universitat Auṭnoma de Barcelona (UAB), in collaboration with a researcher from the University of Chicago, have demonstrated that the origin of natural chromosomal inversions present in the Drosophila fly are found in small independent DNA sequences. These transposable elements could also be responsible of cromosomic changes associated with the evolution of species.

Nature has required species to adapt themselves to their environment through changes in their genetic makeup. These changes, known as mutations, can come about by various means, from a base substitution in a DNA molecule to major alterations in one or more chromosomes. Most often, these mutations are prejudicial and are eliminated by natural selection, but they can be favourable increasing the carrier's capacity for survival and reproduction and, in time, lead to new species.
