Seed Dispersal Under the Threat of Mustard Bomb – Michal Samuni-Blank (2012)

January 27, 2015 at 11:35 am / Ecological Documentaries, Evolution, Natural history, Video

Plants evolved diverse ways to disperse their seeds using animals. To give a few specific examples Long-wattled umbrella birds, Toucans and fruit eating bats are known for effective dispersal of palm tree seeds by eating the fruits. These dispersers regurgitate or defecate seeds after flying far away. On the other hand, most fruit eaters are also seed predators. Unlike birds and bats other animals such as agoutis, monkeys, peccaries and tapirs can chew and destroy the very same palm seeds. […]

The Making of a Theory: Darwin, Wallace, and Natural Selection – John Rubin – HHMI (2014)

January 20, 2015 at 2:36 pm / Evolution, Video

This documentary does it right. The theory of evolution was co-discovered independently by two biologists that lived within the same time period. Darwin and Wallace were well known in their time but Wallace’s name gradually has been overshadowed by Darwin. Today we rarely (almost never) hear the name Alfred Russell Wallace. This documentary does a good job to revive Wallace’s name. Wallace was quite an impressive personality and his life most certainly was inspirational. He knew what “survival” really meant. […]
