The virus that causes AIDS, HIV (Human Immunodeficiency Virus), derives from SIV (Simian Immunodeficiency Virus). SIV can only i

nfect monkeys. People who hunted wild monkeys were not susceptible to SIV infection because the host range of the virus was species- specific (i.e., restricted to monkeys). Then all of a sudden. SIV gained the ability to infect humans and the HIV/AIDS pandemic began. As a geneticist, how would you explain this? You may answer in very general terms.

Answer:

it can be explain in such a way that there might be a kind of likelihood of cross-species transmission when a person is exposed to one strain versus another.'

it was found through research with  evidence that SIV strains mutate when they enter cells to overcome human-specific barriers to infection, something that had been suspected for a long time.

Explanation:

The first strain of a virus considered the ancestor of HIV, the virus that causes AIDS, was passed to humans in the early 1900s, somewhere near a West African rainforest. Now a study has backed up this theory, by proving forms of HIV can cross between chimps and humans.

Mutation

In genetics, any heritable change of the base-pair sequence of genetic material is referred to as MUTATION.

Some Caminalcules went extinct without leaving descendents. In the real world, what factors might increase or decrease the proba
katrin2010 [14]

Answer:

Lack of diversity = higher chance of extinction

high levels of diversity = higher chance of survival

Explanation:

The probable reasons behind the extinction of some Caminalcules are:

The ratio of males and females were not equal so that there were natural fight between male Caminalcules to get a female. This was one of the cause for lowering the population leading to extinction.

The excessive short-life of these Caminalcules was one of the main reason for their extinction as it is more difficult to real organisms because there would be an inherent bias against observing these species in fossil aseemblegs.

5. The two vestigial structures of Caminalcules were ear muscles and tail bones.
