You are an individual. Nothing is going to happen to you evolution wise. You are what you are. You will live and die as you are.

Evolutionary changes and effects can only happen over broad time spans and large populations. If a new disease, like bird flu for instance, strikes large populations, some people will survive to reproduce and some won't. Natural selection refers to those who will survive and produce offspring that is not susceptable to the same disease.

You can get a mutation, but compared to the rest of humans, how significant is that mutation (whether it be good or bad or neutral). What has to happen is a shift in the frequency of an allele eg from black to white fur, red spots to yellow spots,etc etc.
If you are successful and have offspring...maybe lots, even in the space of a couple of generations, you and your offspring (and their children) could die out and still have no effect on how the population looks, behaves etc.

A mutation can start in an individual, but the whole population needs to be affected and change (beneficially for the conditions at the time). If over time there are enough changes to the population by natural selection, a new species may occur.

Some changes in populations can occur faster if a. you have a small population, or certain members of a population set up a new population (founder effect) (eg armish people moving from germany are have diff blood types more common and a higher incidence of polydactly) or if a large proportion of the population dies out for some reason (bottleneck effect). A small change can be magnified in a small population.
Hope this helps

Natural selection as it refers to evolution and duration of a species, means that the strongest survive and reproduce. Also the species most suited to climate and habitat change will thrive while those whose natural attributes don't bode well will die off.

In a sense there is a time when an individual is affected such as an animals death by a predator or killed by rival male for breeding right.
While most Bi's would say the overall process is in the total changes in population, it would be hard to convince the victim!

characteristics that are genetically exceeded down that provide reward to a species will enable that species to proceed to exist greater ideal. A mutation interior the technique (you will possibly be able to call it God's fingerprint in case you like, yet scientists might call it a mutation) can help or injury a species. you could finally end up with 6 arms on a hand, downs syndrome, or the flexibility to technique lactic acid greater ideal. If it truly is something like the latter, and you mate with somebody else with that trait, your offspring will maximum probable have the trait besides. If this supplies greater effective persistence, then while issues bypass truly incorrect, and you will possibly desire to run on your lives to proceed to exist, your offspring have a greater ideal hazard. The giraffe isn't morphed from a horse or despite in one era. If there's a god and (s)he wanted a giraffe, why make the technique take so long?
