It’s an elegant series of genetic steps that evolved millions of years ago, for a reason much bigger than beauty!
For most of the year, deciduous trees are More >
Can I Teach That?

Recently I worked with a group of graduate students who volunteered to be science mentors for students in New York City. They were being trained in a small set of hands-on labs designed to introduce genetics in an engaging, informal environment. At some point during the training, we touched upon genetic mutations and variation. I mentioned that it was a perfect segway into discussion of natural selection and evolution. One participant raised her hand and asked, “Are we allowed to teach that?” My initial response was surprise. I said, “Of course!” It is unfortunate though, that as science educators we should even More >
