Tips From Teachers

“Did you ever wonder why some adults can drink milk and eat ice cream without any problems, while others get stomach aches and produce a lot of gas? Well, the Howard Highes Medical Institute has just released a short video that answers that question [...] Got Lactase? The Co-evolution of Genes and Culture is an excellent video, albeit only 15 minutes long […] It would be a great asset to biology and anatomy classes studying genetic inheritance, evolution, digestion, and enzyme behavior.” -- Jeffrey D. Sack, American Biology Teacher, January 2014
