Adaptation as far as I understand is caused by genetic mutation. Genes disappear. They duplicate. And so forth. Mutations by their nature are mistakes or accidents. There is nothing directing the mutations. Some mutations improve the survivability of the organisms. This is adaptation. Those adaptations are preserved by natural selection. Natural selection is the thought that organisms with that are more adapted will be more successful in reproduction statistically generation over generation. In some cases organisms will make reproductive decisions which is is an example of guided natural selection. However, the basis of evolution is genetic mutation of various kinds which is not guided by any force or intelligence.
