If you watched the recent Cosmos series and are looking for another high quality, entertaining science documentary series, I highly recommend Your Inner Fish by Neil Shubin. It's available via streaming on Netflix. It's a shorter series than Cosmos with only three episodes, but each of the episodes is amazing! Your Inner Fish discusses the topic of evolution. Shubin does an excellent job explaining complex concepts and is very energetic. Check it out. It's a great rainy afternoon time killer!
