It's Always Sunny - evolution versus Christianity

[Pat Mustard]

Sorry, I missed where I said that....... could you point that out for me, the bit where I said that a huge population of humans came from nowhere?  Or are you creating a big man made from straw?

Anyhoo, I must admit, I'm no subject matter expert here......but the most basic understanding of genetics leads even a layman like me to suggest that thinking the entire human race came from 2 people to be a special kind of stupid.

Look Genius,

My brother in-law breeds dogs (American bully's), There is a lot of inbreeding early on, which is how you solidify traits that you want.

Inbreeding is the mating together of closely related dogs, for example mother/son, father/daughter and sibling/sibling matings. For breeders, it is a useful way of fixing traits in a breed—the pedigrees of some exhibition dogs show that many of their forebears are closely related. For example, there is a famous cat by the name of Fan Tee Cee (shown in the 1960s and 1970s) who has appeared in more and more Siamese pedigrees, sometimes several times in a single pedigree, as breeders were anxious to make their lines more typey. Superb specimens are always much sought-after for stud services or offspring (unless they have already been neutered!), having won the approval of show judges.


However, inbreeding holds potential problems. The limited gene pool caused by continued inbreeding means that deleterious genes become widespread and the breed loses vigor. Laboratory animal suppliers depend on this to create uniform strains of animal which are immuno-depressed or breed true for a particular disorder, e.g. epilepsy. Such animals are so inbred as to be genetically identical (clones!), a situation normally only seen in identical twins. Similarly, a controlled amount of inbreeding can be used to fix desirable traits in farm livestock, e.g. milk yield, lean/fat ratios, rate of growth, etc.

Now The bible says we started with 2 humans, and those humans lived over 900+ years, currently we're lucky if we live to 90.

Do the math.

Huggy, the fact is we live longer now than any generation that existed before us. Back in the Roman empire you could expect to live 25 to 30 years, unless you were lucky enough to be rich and survive infancy (child mortality befor 5 was, at best 50/50). And all the evidence from arcaeology from before then suggests you were ancient by 40. There is no way that in 4000 bce or whenever people lived to be 900, we'd have found evidence.

Oh, and on your idea about selective inbreeding being the cause, we know what that does, just look up the Spanish Habsburgs some day. It doesn't make people's lives 10 times shorter, it makes them much more prone to genetic defects. What you are proposing is that a gene pool of two lead to us. This is impossible, a gene pool of two would have lasted about five generations before irreprable genetic collapse and species extinction.
