Far from random, evolution follows a predictable genetic pattern, researchers find

Reading Time: 5 minutes Evolution, often perceived as a series of random changes, might in fact be driven by a simple and repeated genetic solution to an environmental pressure that a broad range of specieshappen to share, according to new research.

Princeton University research published in the journal Science suggests that knowledge of a species’ genes—and how certain external conditions affect the proteins encoded by those genes—could be used to determine a predictable evolutionary pattern driven by outside factors. Scientists could then pinpoint how the diversity of adaptations seen in the natural world developed even in distantly related animals.

Happy Thomas Hunt Morgan Day!

Reading Time: 2 minutes If Gregor Mendel was the Father of Genetics, Thomas Hunt Morgan, whose birthday we celebrate today, was the Godfather of Genetics.  He was the first to win a Nobel Prize for genetics and, from his lab, several of his students went on to earn their own Nobel Prizes thanks in part to his mentorship. So […]

‘Psychopaths’ have an impaired sense of smell – a slight bouquet of determinism

Reading Time: < 1 minute  ScienceDaily (Sep. 20, 2012) — A new study suggests that a poor sense of smell may be a marker for psychopathic traits. People with psychopathic tendencies have an impaired sense of smell, which points to inefficient processing in the front part of the brain. These findings by Mehmet Mahmut and Richard Stevenson, from Macquarie University in […]
