Plasticity is a normal part of development: a contextually integrated view of life, environment: filter + source of variation, according to charles darwin the environment is a sort of filter. Because of this species evolve: but the environment is also a source of variation. It affects biology: video national geographic: reproductive system of green spoonworm (underwater organism). larve that go upwards become male. larve going down become female, > so environment is influencing part of their biology. It depends on the environment: someone who trains a lot, lots of exercise, has a different phenotype. Same gene set: polyphenism (a polyphenic trait is a trait for which multiple, discrete phenotypes can arise from a single genotype as a result of differing environmental conditions. It is therefore a special case of phenotypic plasticity - It is said that everyone can learn this if they are very young: bbc article: the sea nomad children who see like dolphins.
