Speaking of which, why do they need to keep the wings?

Why? You couldn't build a better roof-truss than a wing of a 747. It's a huge structure designed to support lots of weight.

Um, roofs do not need to support a lot of weight, there's generally nothing on top of them. Unless you happen to live in Buffalo, NY and are carrying a heavy snow load. But this house is being built in Malibu. Weight loading on this roof is not a factor.

And the structural elements inside an aircraft wing are optimally designed to distribute the loads typically found on a wing, not a roof. Even a half-assed engineer could design a truss system better suited to a roof than a jumbo jet wing.

Yes, photosynthetic slugs have been known for years (decades). What was unknown was whether any of the genes required for photosynthesis have been incorporated into the genome of the animal as opposed to solely using the genetic material in the consumed chloroplasts. (Yes, chloroplasts do have their own genome.) It was just now shown and reported that the genes to make chlorophyll have in fact been stably incorporated into the slug's genome. That is news.

No, the statement is essentially correct. The slugs harvest (i.e. gain) energy via trapping photons with chlorophyll. They store that energy as chemical bonds in sugar molecules. They then release the energy as needed by metabolizing the sugar. Photosynthesis is the coupled capturing and storing of energy so saying that it "gains" energy via photosynthesis is a reasonable simplification.

First the "six possible changes" is only referring to single nucleotide polymorphisms (SNPs), which is the substitution of on one base for another. There are more complex alteration, insertions, deletions, inversions, etc. are not counted among these six. For a SNP to become "fixed", that is stably maintained through subsequent replication cycles you have the initial mutation event (altering a base) but then you must also have the complementary substitution on the other strand of the double helix. If an A is changed to a T on one strand then the complementary T must subsequently be changed to an A to maintain complementarity of the double helix. Once the mutation is fixed it is impossible to tell if the original mutation was the A->T, with complemnting T->A, or vice-versa. More properly these mutations are written as change in the paired bases AT->TA. An AT->TA is indistinguishable from TA->AT. The six possible changes are:

AT->GC
GC->AT
AT->CG
AT->TA
GC->TA
GC->CG

I tried using ARD once. You have to license the shit for every workstation.

Bzzzzzt, wrong. Sorry, thanks for playing. Apple Remote Desktop is $499.00 for an UNLIMITED number of managed clients. You license the management computers, not the clients. You would buy one copy of ARD Unlimited for each administrator's workstation.
