Different non-human animals unwillingly help humans with creating medicine that can treat certain human diseases. For example, the anticoagulant properties of snake venom are key to potential medical use. These toxins can be used to treat heart disease, pulmonary embolism, and many other diseases, all of which may originate from blood clots.
The results of reconciliation ecology can also improve human well-being. E. O. Wilson has hypothesized that humans have an innate desire to be close to nature (see Biophilia), [26] and numerous studies have linked natural settings to decreased stress and faster recovery during hospital stays. [27]
In the previous 11,000 years, humans have brought a wide range of species into domestication to use as livestock, working animals, household pets, and companions. [27] The influence of human behaviour on domesticated animals has led to many species having learned to co-exist - sometimes leading to the formation of an interspecies friendship.
Devolution, de-evolution, or backward evolution (not to be confused with dysgenics) is the notion that species can revert to supposedly more primitive forms over time. The concept relates to the idea that evolution has a divine purpose and is thus progressive (orthogenesis), for example that feet might be better than hooves, or lungs than gills.

Scholars have traditionally divided uses of animals, [1] plants, [2] and other living things into two categories: practical use for food [3] and other resources; and symbolic use such as in art [4] and religion. [5]
Bred-back breeds are desirable in conservation biology, as they may fill an ecological gap left open by the extinction of a wild type due to human activities.As long as food preference, behaviour, robustness, defence against predators, hunting or foraging instincts and phenotype are the same as in the wild type, the bred-back phenotype will function similarly in the ecosystem.
