Can you explain me the evolution theory and the giraffe thingy ? how did 1 "darwin" person make such chaos ?

1. 2 is Lamarckian evolution, which has been amply disproven. The USSR continued to believe in Lamarckian evolution well after the scientific community had agreed it was false because they thought it better represented their Socialistic dogma. As a result, they fell far behind in genetics and evolutionary biology. The moral is: letting dogma make you deny evolution is a very bad idea and makes you a socialist.
