Office Visitor

Had this visitor outside our office door this morning.

May be true but, other moth populations have changed from white to dark wings in just a few years, in a survival response to changing background colors with which it was advantageous for them to blend in.

Such rapid changes may be due to epigenetic inheritance rather than actual changes to the inherited DNA nucleotide sequences. One example of epigenetic changes is methylation (a methyl group (CH[sub]3[/sub]) attaching itself to the A or C nucleotides) of portions of the DNA sequence that don't get completely "reset" in reproductive cells when they should, thus possibly passing an environmentally triggered change in the parent's gene expressions to the child. At least that is the cliff notes version as I understand it. I believe it is a hot area of research.

You have it all wrong. Ganglean Theory clearly states that the perameters for carcation mutations must be bernillified before said delorification can occur. That said, the prodigious postifications you expound upon could be concievable provided that the prolific postpartem postifications which you purport to be possible pass the proper and punctillious scrutiny in the scientific community. Bernillification simply cannot take place in the binary canamofluous environments, and therefore, sir, your statement here is false.

D'oh! That is all so clear and obvious. How foolish of me not to realize that! Thanks for pointing that out.
