HIV virus is one of the most pressing health concerns facing the modern world. Since the first reported case of HIV/AIDS in 1981, over 25 million people have died. Out of the millions of people infected each year with the HIV virus, a few have shown HIV/AIDS resistance. A genetic mutation found mostly in people of European descent delays the progression of AIDS and in some cases even brings about immunity.
For much of nature, natural selection and ‘survival of the fittest’ still play a dominant role; only the strongest can survive in the wild. As little as a few hundred years ago, the same was true for humans, but what about now?
German American physicist Albert Einstein?s theories changed the course of human history and shaped modern physics. He, on the other hand, assumed a static universe although his own theories pointed to an expanding or a shrinking universe. Einstein, however, calibrated his by-then widely accepted theory to make it fit for his assumption. When an American astronomer Edwin Hubble proved beyond doubt that the universe was expanding, Einstein called his own wrong assumption as the biggest blunder of his life. Einstein was neither the first nor the last scientist who fell into this trap.
Under occupation, Danish farmers were banned from raising their home country?s flag. In protest against the flag ban, farmers came up with an ingenious idea. The farmers would raise a new pig breed in protest.
In the second of the nineteenth century a fierce debate broke in the scientific community about Darwin's theory of evolution. However, by the twentieth century the debate was over.
Potatoes grown by cloning are cheap and plentiful, but they share the same genetic information, which makes them vulnerable to the same potato diseases.
Virtually all live-born babies grow up to have their own babies. Does this mean human natural selection, hence the evolution of humans, is coming to an end?
World Health Organisation estimates worldwide there are 1 billion cases of influenza annually. We catch the flu, recover from it, but we are not off the hook, we can catch the flu again.
Little did the English economist Thomas Malthus know, with the publication of his book in 1789 he was rolling a snowball that would soon turn into an avalanche.
