		<description>Sorry for the extra post. One typo I can let go, but not three:

Josephine*

I fully understand *and* agree

made absolutely *no* sense to me</description>

		<description>So is mollusc marriage now under threat from gay clams?  Congress (or Parliament) better write up a Defense of Invertebrate Marriage Act.

Edit: Oh, and in all seriousness, Jospehine (#3), I fully understand agree with what you mean.  Biochemistry made absolutely so sense to me until I realized, &quot;Oh, these enzymes don&#039;t *want* to find lactose and break it apart, they just do it based on their shape!  That transcriptase doesn&#039;t *know* where to find strands of DNA to copy, it just bumps into them!&quot;

Edit2: Oh, to answer your actual question, I think it&#039;s easier to explain in casual terms that &quot;Protein A *wants* Result X,&quot; and &quot;Virus B *attacks* Cell Y.&quot;  If the audience is really thinking about it, and doesn&#039;t understand where the intent comes from, the &quot;accidental&quot; explanation would come in handy.  The intent-laden terms can be more correctly interpreted from then on.</description>

		<description>Cheating on asexuality, as practised by the aforementioned species raises the important point of whether their cheating is an evolved mechanism, or just an accidental mishap, i.e. have the clams evolved to parasitise the eggs of related species, or is it just a chance fertilisation which injects a well-needed but purely accidental genetic contribution into the gene pool? Same for the rotifers; they have probably not been selected for their ability integrate foreign DNA into their genomes; it&#039;s just a lucky accident that helps an asexual lineage shuffle along for a few generations more.

I raise this point because there is such anthropomorphising in biological explanations; it makes one wonder about intent, such as in &quot;proteins want&quot; etc. In my first year of university it confused me to no end. How could inanimate molecules have intent? What was the -real- underlying reason for their &quot;behaviour&quot;? -Then- I understood the randomness of it all, and it made so much sense.

I don&#039;t know: do other people feel the same way? I honestly have no idea, and that&#039;s why I ask. What is easiest to understand; clams cheating with intent, or genetic injections being nothing but fortunate accidents?</description>

		<description>It is amazing to me that a species can remain viable when splicing in random chunks from species evolved for a different way of life.

It&#039;s almost as if those spider goats used to produce silk protein had somehow evolved naturally by eating dead spiders one day when they were starving and absorbing their DNA.</description>
