What is the origin of the Species?

I find ecological biodiversity (and its history) phenomenally interesting. The whole subject of life cycle and the proliferation of various species will never cease to amaze me.

Charles Darwin‘s ‘On the Origin of Species’, was always the scientific literature considered to be the foundation of evolutionary biology. There are some who have challenged Darwin’s work over the years and sorry to upset you Charlie boy; I am starting to think I may have to join the dissenter’s camp.

Although I understand and support many of the concepts and theories, there are elements which cause me confusion and in particular, the seemingly unstoppable proliferation of the great British Chav, also referred to by some theorists and commentators as the ‘underclasses! As usual, not wishing to make unrehearsed assumptions, I turn to the internet for answers to alleviate my quandary…

Biological classification: or scientific classification in biology, is a method by which biologists group and categorize organisms by biological type, such as genus or species.
Evolution: is the change in the inherited traits of a population of organisms through successive generations. After a population splits into smaller groups, these groups evolve independently and may eventually diversify into new species.
Evolutionary: A group of organisms that shares an ancestor; a lineage that maintains its integrity with respect to other lineages through both time and space. At some point in the progress of such a group, some members may diverge from the main population and evolve into a subspecies, a process that eventually will lead to the formation of a new full species if isolation (geographical or ecological) is maintained.
Copulation: may or may not be related to reproduction; for example Chimpanzees (Pan troglodytes) and especially Bonobos (Pan paniscus) are known to copulate when the female is not fertile, presumably for pleasure, which in turn strengthens social bonds.

Thank you Google and Wikipedia!

So with a scientific approach I search for answers however, typical of that scientific process, further questions appear to be raised;

Could the Chav be a whole new species or, is it simply a sub-species caused by the evolutionary process but not yet fully evolved?
If the above is correct, should we be worried about it and if so, is this actually a worrying feature of our future society or a bonus?
As a Chav is similar to (but not the same) as your regular human being, on which side of the answer to (1) above does the Chav actually sit?
If we are in fact worried about the results of the evolutionary process, what (if anything) should we do to try to influence the remainder of that evolution process?
If we try to influence that evolutionary process, are attempts at social engineering enough or indeed, a step too far?
It appears regular human beings and the Chav actually share the same ancestry. If this is correct, from where/who did they inherit their prominent traits during the evolutionary process?
If the Chav evolved from humans, what or where did we go wrong, if at all?
If we are unable to impose any meaningful influence on the evolutionary process, one that often appears genetic as opposed to social; would it be correct for society to attempt a genetic engineering solution?
Given the fact copulation may or may not be related to reproduction, irrespective of any prominent social housing or financial support needs of the individual, is there a need for proliferation education or perhaps even enforced sterilization?

My scientific assumption at this stage is; Britain is populated by a diverse range of human beings from all manner of ethnic and social backgrounds. There is also an emerging and ever-growing sub-species of human (genus; Homo-Chavus Arsolious). This sub-species is (thus far) only partly evolved however, given its ability and propensity for prolific reproduction, it is highly likely the genus could actually evolve as the prominent species of the future.

The question that requires an urgent answer now is; what (if anything) do we need to do about it? And, why are there so many bloody questions and no apparent answers?
