In 1939, Paul Muller discovered DDT that killed insects. Because of that discovery he won the Nobel Prize in 1948. But before the ceremony even happened some insects were already resistant to the antibiotic. This shows how fast evolution occurs. Human technology supports the fact that evolution happens quicker. Some examples from the Palumbi (2001) are HIV and how it spreads and is resistant to strong antibiotics. Technology and humans pressure affects the spread and resistance of HIV because they try many different medicine, and antibiotics to try and stop, but it just makes the virus more resistant to strong antibiotics. Another example of human pressure and technology affecting evolution is the fish in the ocean. Because of the fishermen overfishing in the sea the fish evolve slower growth rates and changes to be smaller so it could escape through the nets. These examples show how human technology and their selective pressure can lead to rapid evolutionary change.
Palumbi (2001) talks about HIV and how it has an affects a lot of people. After HIV has been found the virus continually evolves and gets immune to antibiotics. Humans try to cure this but cause the virus to become more powerful and resistant to the cure. One way of slowing or controlling this evolution of HIV can be not to force or pressure the virus. They should slow down and figure out before the bacteria becomes resistant and powerful! Even if people panic at this virus and humans try to cure it by giving them all kinds of medicine can lead the virus to be eternal and never be curable. This will be desirable because then HIV might actually have a cure. When people think and do more research then just going in and giving them all kinds of antibiotics, might be a smarter thing to do in the long run.
Another example that leads to rapid evolutionary change caused by humans can be some fish in the sea. Humans overfish in the sea, which causes the fish to change. When fishermen use their nets to...
