  The Botany of Desire – Michael Pollan – PBS (2009)

  February 15, 2012 at 10:40 pm / Evolution, Human Nature, PBS Nature, Video

  Domestication is a defining feature of recent human evolution. In animals first trait selected by humans was behavior. In plants harvestability through selection of non-shattering seeds was the first trait of domestication. Plant domestication paved the way to agriculture which enabled highly specialized sedentary human societies. Domesticated plants differ from their wild ancestors in distinct ways that can be categorized under a term called as the domestication syndrome. Domestication syndrome includes reduced shattering of seeds (seeds don’t separate from the […]

  Ants, bees and wasps make up only 3 percent of animal diversity yet they may constitute up to 50 percent of the total animal biomass in land habitats. Bert Hölldobler is a leading entomologist (scientist who studies insects). He collaborated with ant biologist E.O. Wilson and developed the field of Sociobiology. The documentary does an excellent job introducing us observations coming from both natural and laboratory setting. First observation comes from the European red wood ants (Formica polyctena). These ants […]

The wasp began eating by chewing the abdomen first and later flew over to the top of a kudzu vine (Pueraria montana) to eat the rest. Although […]

  Daytime Hunting of Barred Owl (Strix varia)

  On April 16th 2011, a barred owl glided over my head while I was filming something else along the Orange Trail of the State Botanical Garden of Georgia in Athens, GA. Hunting during daytime indicates that this individual has extra mouths to feed. You can hear the altruistic alarm calls of other nervous birds and rodents. The high pitched alarm call (of a chipmunk?) is particularly audible immediately before each move of the owl. I deliberately kept the scenes long […]
