Firstly, dam those uppity "Proles" for demanding housing provision. 65 to a bed in a tied cottage was good enough in Great Uncle Fitzchinless's day, and it should be good enough now.
Secondly, my brain is reeling with realisation that there are people who actually think that inbreeding is a good thing. I mean WTF?
In breeding does not produce "racers", if what is meant by the term, is an animal who wants to race. Inbreeding over generations has simply produced fast horses by focusing on the exageration of physical charactaristics which lend themselves to speed. Namely, elongated limbs, light bones, streamlined body shape, large heart and lungs.
(It also pruduces along the way, all the health problems associated with the expression of those exaggerated charactaristics, many of which I mentioned in an earlier post, not to mention the poor disease resistance and lack of hybrid vigor demonstated by by all inbred species, and the high incidence of birth defects exhibited in all populations (including human ones) with a restricted gene pool. And yet purported "horse lovers" and "horse experts" think that inbreeding is a good thing!!)
So, back breeding achieves a change in bodyshape and physiology, to produce a faster animal. What is does not do, is produce some sort of change in the psychological and behavioural traits of that animal into the behavioral traits of a different species, namely, the human species.
Racing, winning, betting, recreational competitive sport, do not exist in the animal world, they are wholly human constructs. Wild animals are too busy trying to stay alive and if they are lucky , achieve a spot of procreation along the way. sport doesnt figure.
Several million years of evolution has produced the modern horse, as a herd dwelling, grazing, herbivore. They do not race, it has no meaning for them in terms of survival. As a prey species, they have excellent vision, fleetness of foot and a hair trigger flight reflex. Human intervention hasnt changed that. A few hundred years of human meddling might have produced physical extremes, from Shetlands, to Clydesdales, to TBs with their exaggerated adaptions for speed.
However, they are all still horses, no matter their body shape, and horses left to their own devices, show no inclination to gallop flat out for miles and hurl themselves at obstacles. They only do so for one reason, that reason being to escape from a perceived predator. Infact any inclination to do so would be a positive evolutionary disadvantage, as such behavior would lead them to the same same sorry fate as the poor sods in yesterdays race, and hence their removal from the gene pool. So such behavior would be actively bred out of the population.
If horse breeders, in changing the appearance of an animal, have also changed its entire biology from that of a prey species, to that of a predator species (man), to produce a so called "racer", who loves to race and understands winning, and not just a fast horse, then they have achieved what the finest medical scientists and molecular geneticists have never been able to do( and dont expect to be able to do for decades.)
Unlikely.
What we actually have are poor sods being exploited and maimed in the name of a fast buck and a public appetite to experience danger vicariously in bloody spectacles like the Grand National.
