Period 7 Biomedical Research

Isolation within one infected person, plus differing conditions and struggles to survive, forces each version of HIV to evolve independently. Understanding how quickly HIV can evolve to develop immunity to certain drugs (like AZT) have been crucial to reducing deaths by HIV and slowing down the evolution of the disease within patients.

Humans may be the dominant evolutionary force because as we continually develop methods of poisoning other organisms (like using insecticides to kill pests), they are evolving into organisms that are less vulnerable to that particular poison, in order to stay alive.

"In gene therapy, AAV can be used to deliver beneficial genes to human cells. The problem with using AAV is that when AAV is injected for gene-therapy purposes in these people, their immune system attacks and destroys the virus before it has a chance to deliver its therapeutic genes to their cells.
Using “directed evolution,” scientists mutated the viral DNA and selected the mutants that were able to survive more antibodies against AAV. By repeating this process several times, they found mutant virus strains that withstood large doses of AAV antibodies. These mutant AAV strains therefore could be more beneficial for gene therapy."

The most urgent and beneficial part of Biomedical Research today is the study of microbial diseases. This is very important to us because as we evolve, the threat of diseases is very large, so this research is very useful and very important to us at the moment.

Humans are much similar to mice than one would originally think. Both mice and humans have the same amount genes. Studying these genes may be the key to finding new cures for diseases and other medical issues.

"Biomedical research can be divided into two general categories: the evaluation of new treatments for both safety and efficacy in what are termed clinical trials, and all other research that contributes to the development of new treatments." (

Speciation is the other major phase of evolutionary change. It doesn't change often and is more elusive than anagenesis. The process is spread out over thousands of the generations, but it may end unexpectably when the last change occurs. Speciation is the process where new species are created through the evolutionary process.
