3 billion base pairs is a pretty typical genome size for organisms like us, but there are a few plants and animals with genomes so huge they completely blow this number out of the water. Hosted by: Olivia Gordon

Strawberries are delicious, but for a molecular biologist, they're also very difficult.

Paul Andersen details the evolutionary processes of speciation and extinction. Stickleback evolution in Lake Loberg is used as example of rapid speciation. Adaptive radiation is illustrated using the Hawaiian honeycreeper. A brief...

Paul Andersen explains how reproductive isolation can eventually lead to speciation. Three main barriers to gene flow are included: geographic, pre-zygotic and post-zygotic. Both allopatric and sympatric speciation are discussed. A...
