Poaching is the illegal hunting or capturing of wild animals. Both male and female African elephants have tusks that are a significant source of ivory used for ornaments and jewelry. Assuming that the size of the tusks is heritable, which of the following is the most likely long-term effect of poachers targeting African elephants with large tusks? An increase in average tusk size because of the need to provide more ivory for the poaching hunters B A decrease in average tusk size because elephants with large tusks are less likely to survive to reproduce An increase in average tusk size to provide the elephants with a defensive mechanism against poachers D A decrease in average tusk size to reduce the energy investment in the tusks

Conservation Biology

The study of how to prevent the loss of biological diversity on the planet is called conservation. Biological diversity, also termed biodiversity, consists of various life forms found in a specific location or across the entire planet, including ecosystems, species, populations, and genes. Conservation thus aims to protect the diversity of life at all levels of biological organization.
