With the proper signals, they will stay, heel AND fetch.

This is awesome! LoL Kids are little friggin recording machines. They would make awesome stenographers...too bad for child labor laws. LoL

In any case the problem with DNA lengthening is described by historic cases where interspecies breeding was successful in producing viable offspring. DNA can be lengthened or shortened by this process and explains why humans have one less DNA strand than the other Great Apes.

Chromosomal polymorphism

In genetics, chromosomal polymorphism is a condition where one species contains members with varying chromosome counts or shapes. Polymorphism is a general concept in biology where more than one version of a trait is present in a population.

In some cases of differing counts, the difference in chromosome counts is the result of a single chromosome undergoing fission, where it splits into two smaller chromosomes, or two undergoing fusion, where two chromosomes join to form one.

This condition has been detected in many species. Trichomycterus davisi, for example, is an extreme case where the polymorphism was present within a single chimeric individual.[1]

It has also been studied in alfalfa,[2] shrews,[3] Brazilian rodents,[4] and an enormous variety of other animals and plants.[5] In one instance it has been found in a human.[6]

Another process resulting in differing chromosomal counts is polyploidy. This results in cells which contain multiple copies of complete chromosome sets.

Possessing chromosomes of varying shapes is generally the result of a chromosomal translocation or chromosomal inversion.

In a translocation, genetic material is transferred from one chromosome to another, either symmetrically or asymmetrically (a Robertsonian translocation).

In an inversion, a segment of a chromosome is flipped end-for-end.
Implications for speciation

All forms of chromosomal polymorphism can be viewed as a step towards speciation. Polymorphisms will generally result in a level of reduced fertility, because some gametes from one parent cannot successfully combine with all gametes of the other parent. However, when both parents contain matching chromosomal patterns, this obstacle does not occur. Further mutations in one group will not flow as rapidly into the other group as they do within the group in which it originally occurred.

Further mutations can also cause absolute infertility. If an interbreeding population contains one group in which (for example) chromosomes A and B have fused, and another population in which chromosomes B and C have fused, both populations will be able to interbreed with the parent population. However, the two subpopulations will not be able to breed successfully with each other if the doubling of chromosome B is fatal. Similar difficulties will occur for incompatible translocations of material.

Juxtaposing those two questions, linked with 'or', implies to me a false dilemna.

Scientists can extrapolate, and they can make reasoned inferences. This does require some observations, but it does not require that every single facet of a process is directly observed. But you don't need to see a bullet in flight to 'observe' someone shooting a can off a wall. (Though admittedly a radical skeptic might say: Are you sure the bullet didn't miss, and something else knocked the can off the wall? This possibility doesn't make it unreasonable to conclude the person who fired a gun directed at the can almost certainly did shoot the can off the wall.)

So how do we know a mutation has happened? It's been over a decade since I've formally studied this, so my knowledge is both rusty and outdated. In the old days, people would have some evidence that a mutation might have happened (such as new physical qualities not previous observed), and go hunting for it. They might breed the organism, and look for linking of that quality to other known genes, and help them narrow down which chromosome its on. I don't know the details beyond that.

My understanding is that we can also draw inferences regarding when mutations may happen by comparing sequenced genomes of closely related species.

It seems like we are about to enter a new age of cheap sequencing, in which sequencing a genome may be as easy as tagging a migratory bird or growing bacteria in a petri dish. This will eventually give us a massive database of genetic information. We may develop new ways of analyzing this data which can tell us a great deal about the pace and timing of mutation. This may or may not be 'observation' depending on your definition. To take the strictest view of 'observation', we would actually have to catch the exact moment of the mutation and image the dna at the atomic level. This has never happened, and quit possibly never will.

I do completely agree with you on this. The only problem I have with current evolutionary theory is they try to use it to explain increased complexity in the DNA.
That is merely an interesting idea, a hypothesis, not even a theory.

One of my daughter's friends' mother is a pagan /witch. Him and his friends decided to do a summoning, which he read in one of the mothers' books. All 4 friends saw the demon that appeared. Not a nice end to the story either...dangerous stuff.

I don't reply to dumb messages. Someone who emails me a "Hi, how are you?" ... yea.. just seems dumb to me. More effort is needed. Just seems useless to write back "good and you". I am obviously ok..if I am online.

Feels like i've swallowed a ton of paper towels. Yeah. Next time I'll be sure to not eat in my sleep. If i ever did. It feels so dry.

I only want it cause the infomercial guy is the one that got arrested for being with prostitutes and at the end of the bit he says you can even use it in awkward situations... then they show him 'schticking' his shirt while posing for a mug shot.

Oh Jesus. Never mind.

LoL! Yea...I'm going to pass on the grilled cheese for awhile.
