African Elephant - Change Over Time. %PDF-1.6 % In his research of the elephant population in North Luangwa, Zambia some 60 percent of the surviving elephants were tuskless, but as conservation efforts allowed the numbers to grow, the percentage of animals with tusks returned to normal. The scientists noted that many in the herd have no tusks or smaller than usual tusks, which makes the animals less attractive to poachers. The researchers tested this hypothesis by undertaking a phenotype/population survey of female elephants and their offspring. Students use scientific evidence and reasoning to construct an explanation of and develop an argument for tusklessness in elephant populations. Arnold said they used simulated numerical models and statistical analysis to determine that a tuskless female elephant was five times more likely to survive during the war than a female with tusks, an example of a very strong natural selection caused by poachers. adaptation, claim, evidence, inheritance, poaching, population, reasoning, selection, selective pressure, variation.

Dr. Michael D. Kock, a wildlife veterinarian who studies African elephants, is doubtful that the increased number of tuskless elephants is due to natural selection. But if this trait was traditionally X-linkedpassed down along the X chromosome, which helps determine sex and carries genes for various inherited traitswe would think that because males always get their X chromosome from their mothers that youd have a really large population of males that are tuskless. Sharon Adarlo, Center for Statistics and Machine Learning, 2023 The Trustees of PrincetonUniversity, Princeton scientists identify genes behind tusklessness in African elephants facing poaching pressure, A team led by Princeton University researchers has now implicated two genes associated with tooth development in mammals to be at the center of the tuskless elephant phenomenon, according to, Elephants are such an iconic species that is so important for the savanna ecosystem and now we have a better understanding of how human activity is impacting them, said co-first author, Campbell-Staton worked with co-first author, To collect these samples, Campbell-Staton and other research team members focused on African bush elephants (.
