The frequency of different bones and teeth present in a collection can also be informative. For example, this data has been used in the debate about whether Neandertals were hunters or scavengers. It has been argued that hunters would have first access to the carcass they killed and therefore would transport the meatiest bones, such as the upper limb bones of antelopes, back to their homes. Scavengers, however, would only have access to the parts of the carcass that were left behind by other predators and would only get less nutritious parts, such as antelope feet. Animals remains associated with Neandertals that are dominated by the meaty upper limb bones are good indications that they were adept hunters.
Species information also helps researchers better understand ancient environments and how they have changed. For example, zooarchaeologists often look at whether the animals they have identified were adapted for wet or dry environments, and this can help reconstruct the conditions our ancestors evolved in. A collection dominated with species adapted for arid environments might indicate that that location was receiving less rainfall when the animal remains were deposited. Species have also been used to determine the relative date of a site, especially when extinct animals are present. In the past, extinct African pig species have helped determine the relative ages and correlation of different deposits containing fossil hominins.
