O knihe
Insular dwarfism, a form of Phyletic dwarfism, is the process and condition of the reduction in size of large animals - typically mammals but also dinosaurs - when their population's gene pool is limited to a very small environment, primarily islands. This natural process is distinct from the intentional creation of dwarf breeds, called dwarfing.This process has occurred many times throughout evolutionary history, with examples including dinosaurs, like Europasaurus, and modern animals such as elephants and their relatives.There are several proposed explanations for the mechanism which produces such dwarfism, which are often considered likely to be co-contributing factors. One explanation is an evolved gene-encoded response to environmental stress. Another is a selective process where only smaller animals trapped on the island survive, as food declines to a borderline level. The smaller animals need fewer resources, and so are more likely to get past the break-point where population decline allows food sources to replenish enough for the survivors to flourish.
