Because of their remarkable powers of genetic adaptation
, bacteria have been able to mutate and become resistant to every antibiotic currently in use," stated Dr.
The study projected that, through genetic adaptation
, the reefs could reduce the currently projected rate of temperature-induced bleaching by 20 to 80 percent of levels expected by the year 2100, if there are large reductions in carbon dioxide emissions.
We hypothesize that the massive increase in unsterile injecting in Africa associated with the introduction of antibiotics in the 1950's was the modern `event' that allowed several weakly pathogenic simian virus, long native to Sub Saharan Africa, to increase in pathogenicity and complete their genetic adaptation
to human hosts, emerging as the first epidemic strain of HIV by 1959.
Washington, July 10 ( ANI ): For small and short-lived birds, evolution can work fast enough for genetic adaptation
to keep pace with a changing environment, a new study has revealed.
The genetic adaptation
that increases human lifespan is also responsible for making us uniquely susceptible to diseases of aging such as cancer, heart disease and dementia, revealed the study.
When a genetic adaptation
occurs and is passed on to offspring, other genes on both sides of the adaptation typically accompany it.
Some experts think people need to make genetic adaptations
over many thousands of years to withstand such altitudes.
11 ( ANI ): Researchers have suggested that genetic adaptations
for life at high elevations found in residents of the Tibetan plateau likely originated around 30,000 years ago in peoples related to contemporary Sherpa.
The arrival of the Neolithic, with a carbohydrate-based diet and new pathogens transmitted by domesticated animals, entailed metabolic and immunological challenges that were reflected in genetic adaptations
of post-Mesolithic populations.
