Radio Interview

Here's a radio interview that I gave recently for the University's radio station KBGA. On air Tuesday October 16, 2012 from 5-6pm.

About my research

I'm trying to understand general patterns of mammalian speciation. The way I do this is by looking at the problems that occur in mammal hybrids. One common problem is that mammal hybrids often exhibit really wonky patterns of growth. For example, Lions are around 550lbs and Tigers are around 600lbs, but Ligers weigh nearly 900lbs - almost twice as big as either parent. What is more interesting is that Tigons only weigh around 450lbs, much smaller than either parent (remember that a Lion female x Tiger male = Tigon, while a Tiger female x Lion male = Liger). This is crazy because Ligers and Tigons each get about half their DNA from a lion and half from a tiger, so the main question is why is there 450lbs difference in weight between them? While lions and tigers are awesome, I'm trying to understand the genetics that cause these wonky growth patterns using a pair of species that don't routinely eat people: dwarf hamsters. This blog is a sort of research notebook (inspired by none other than Rosie Redfield) that includes my experiments, plans and thoughts on why mammals have such abnormally sized hybrids.
