Here are some interesting scientific stories on cosmology and evolution from the last week. Major kudos goes to MetaNexus, which is a great resources for identifying several of these articles:
Evolution’s Two-Way Street. Scientific American discusses that evolution may be a two-way street: not only have humans adapted to the environment, but the environment has also adapted to human evolution (and not just in the last 1,000 years).
Resetting the Theory of Time. NPR Science Friday had a great interview with Lee Smolin, theoretical physicist, on the meaning of time. I still can’t get my mind around what happens “before” time was created (it is a contradictory statement).
Dog and Human Genome Evolved Together?. From National Geographic, a new study from the University of Chicago argues that dogs were domesticated 32,000 years ago (older than most current estimates) and that they evolved together. As someone with musophobia, I thought the explanation for the symbiosis between humans and dogs and cats was as simple as humans needing someone to take care of the rodents in the caves.
The “Missing Link” Galaxy? Science Daily has an article on the finding of two giant galaxies colliding before exhausting all of the hydrogen in the galaxies. This find is described as “the equivalent of discovering a missing link between winged dinosaurs and early birds.”
Happy Memorial Day weekend to everyone in the United States!
