Document Summary
Most important plant domesticated were the cereals. Domesticated plant changed (just like animals) genetically and physically. Wild wheat: brittle type of plant, when you brush against it, the seeds will fly and that"s how they disperse, for humans they preferred the type where the seeds aren"t as easily dispersed. Cabbage: in the wild form looks nothing like the domesticated plants, yellow flowering plant, many of the current variety was gotten by emphasizing certain types of traits. Remember: the wolf to dog had huge genetic changes: same thing happened with the domesticated plants, first farmer domestication was sheep and goat, dogs were hunting companions. Plant domestication started more than 10,000 years ago. Bitterness - a reduction in bitter taste of seeds, or other parts of certain plants, was promoted: example: almonds. Wild almond -> bitter chemical -> amygdalin -> cyanide poison: bitterness in general is an advertisement of toxicity (protecting itself against seed and fruit predators)
