Discovery of genetic similarities between bats and dolphins

DolphinsThe evolution of similar traits in different species, a process known as convergent evolution, is widespread not only physically but also at the genetic level, according to a new study led by scientists at Queen Mary University of London, in the UK, and published in this week’s edition of the journal Nature. These experts have found genetic similarities between bats and dolphins.

Scientists investigated the genomic basis for echolocation or echolocation, one of the best known examples of convergent evolution to examine the frequency of the process to a genomic level. Echolocation is a complex physical trait that involves the production, processing, receiving and hearing ultrasonic pulses to detect unseen obstacles or tracking prey and evolved separately in different groups of bats and whales .

Egyptian mummies reveal genetic secrets

mummies genetic secretsSoon decoding the genomes of the ancient Egyptians could become commonplace.  This is the opinion of researchers are the first to look at the DNA of the mummies with next-generation technologies.

 

Carsten Pusch of the University of Germany and his colleagues says that they have discovered ancestral roots, pathogens and even plant material allegedly used in embalming.
