Chromosomes

Unusual DNA sequences that have undergone direction reversals have been discovered within the genomes of tilapia fish from Lake Malawi. These genetic structures may accelerate evolution by keeping together genes key to survival and reproduction, perhaps explaining how hundreds of species arose so quickly in a single lake.
