Neandertal (valley) most of the limestone and dramatically changed the shape of the valley. It was during such a quarrying operation that the bones of the original Neanderthal man were found in a cave known as Kleine Feldhofer Grotte. Neither the cave nor the cliff in which the bones were located still exists. During the 19th century the valley was called "Neandershöhle" (Neander's Cave), and, after 1850, "Neanderthal".

Invasive species in Mexico associated with humans as a communal species, and impact an area of 5 km around each center of human population. Their presence is particularly important in oceanic islands (CONABIO, 2008), where they are the predator with the greatest impact on seabird populations. Some examples of species that have been reduced almost to extinction are the Mexican shearwater ("Puffinus opisthomelas"), Cassin's auklet ("Ptychoramphus aleuticus"), and Xantus's murrelet ("Synthliboramphus hypoleucus"). Extinct species include the Guadalupe storm petrel ("Oceanodroma macrodactyla"), the Socorro dove ("Zenaida graysoni") and an endemic sparrow of Todos Santos Island ("Aimophila ruficeps sanctorum"). Cats are a risk factor for the
