Natural Selection In Zoos

Good Essays

Many zoological establishments take pride in breeding programs. Through such programs genetic diversity is currently upheld to a point where euthanasia is required for those animals who either do not make the cut genetically, or are hindering the process of genetic diversity in some way. Should zoos be allowed to continue to preserve genetic diversity regardless of the cost to its current residence? Some people believe that killing the animals involved is unnecessary and poor practice by the zoo. However, others have argued that without the diverse genetics the species would be directly affected by heritable diseases. Zoological parks are a place where domesticated animals are exhibited in captivity. The purpose behind a zoo varies, but they …show more content…

Natural selection is missing among captive domesticated animals. Instead, the zoo staff have to create a controlled environment that simulates the purpose of the Natural selection process. In the wild, or natural habitats, natural selection is a process where the individual that is most suited to the conditions of the ecosystem pass their genes on the the next generation. The equivalent of the process of natural selection in zoos is the monitored breeding programs that ensure the genetic diversity, this is essential as it provides the entire species shelter from genetic diseases that could potentially lead to extinction.
Withholding new genes from a healthy single animal may mean that the animal has to mate with a relative which would produce similar or identical genes. The development of genetic diseases coincides with the development of inbreeding, as the healthy genes are no longer able to be dispersed into the wider community but rather have been cycled back to the next generation. This can have potential consequences on the entire species as the offspring would be susceptible to genetic …show more content…

Zoos should be focusing on animals that already exist within their program. Genetic diversity is important as zoos must do the job of natural selection or risk an extinction of an entire species. This process of natural selection should be revisited as it causes much uprising and is not withholding the promise of protection. To ensure that generations live and grow, disease free, new genes must be introduced. Without these genes the outcome would be a small and likely corrupted gene pool. In my personal opinion, I understand the need of genetic diversity within species as it prevents many diseases. However, I feel that it is inappropriate for zoos to euthanise healthy animals that may interfere with the genetic diversity. Such animals need to be either neutered or relocated, even if it is not transferred to another zoological park but to a game park or national
