example of survival of the fittest

Development of antibiotic resistant bacteria is a great example of the 'survival of the fittest' phenomenon. Can you please give me another example of survival of the fittest?

life on earth (biological concepts from the non-science major perspective)

Can you please comment on a very controversial topic (in my opinion) on the survival of the fittest in humans. It used to be that the weak and sick and underdeveloped infants used to die at birth or shortly afterwards many years ago when the medicine was not that advance to keep them alive on many different drugs and through many different surgeries available nowdays. The strogest infants survived and grew up and produced stronger and healthier children. The weak and the sick died. Nowdays the weak and the sick are kept alive and then grow up and produce the weak and the sick thus taking the 'survival of the fittest' term out of our daily lives. Can you help me with some thoughts and/or int... click for more

Survival of the fittest - bacterial mutations - the flu

Bacterial mutations are a great example of natural selection, especially those that cause the flu. But what happens when we can't develop a vaccine for a certain type of flu bacteria? If it turns out to be a deadly type, think about the population in the big cities that could be effected.

Viruses Mutations

The survival of viruses is a great example of natural selection and survival of the fittest. One such example is HIV. HIV reproduces very quickly (about 10 million new viruses per day. HIV lacks the proteins which repair mutations, and therefore there will be many mutations resulting from this rapid reproduction. The rapid rate of reproduction combined with the many different mutations has had a limiting effect on the effectiveness of HIV therapy using antibiotics. Without the mutations the virus would fall victim to antibiotics. Are there other viruses which have proven difficult to treat because of mutations? What viruses were very deadly and were eliminated because of the antibio... click for more
