Flexi Says: Humans have had a significant effect on the evolution of other organisms. The modern-day maize plant is one such example. Genetic and archeological evidence suggests that maize with multiple corn kernels evolved from its wild grass ancestor Teosinte about 9000 years ago only after it was crossbred and domesticated by the early inhabitants of Mexico.
In addition, the indiscriminate use of antibiotics, pesticides, and other drugs by humans aided in the natural selection and evolution of resistant bacteria and other pathogens which pose a huge threat to human health and nature as a whole. The technological advancements achieved by humans in genetic engineering also contributed to the development of new varieties of economically important plants and animals.
