Perfect Front Door
by Steve Malmude

My summer
is threadbare
these jeans
are chains

always
the sense
of the futility
of maintenance

yet I feel
the cool
night air
from the open door

capital
crosses the border
at will
why not labor.

The MAD (Most Anterior Digit) hypothesis claimed that upon loss of digit 1, a most anterior digit 2 would take over the HoxD signature expression of digit 1, as a result of intrinsic properties of Shh signalling and HoxD regulation [17, 18].

This is a way for digit 2 to be like digit 1 without a frameshift. Only an unlucky rabbit stands in the way.
This possible reconciliation may mean that a PRH type hypothesis is credible. And if so, it would fit in perfectly with a pterosaur to bird hypothesis.

It could be argued that the rabbit is too distantly related to birds and thus irrelevant to discuss the plausibility of events in the evolution of that lineage. However, developmental biologists constantly integrate information from mouse and chicken, even though they are distant relatives. This practice is informative because molecular mechanisms of limb development (Shh expression, HoxD cluster structure) are highly conserved.
I think I will go with the reasonable idea that "the rabbit is too distantly related to birds and thus irrelevant to discuss the plausibility of events in the evolution of that lineage.". After all we have been looking at closely related taxa and there are many, many differences.

Even if a small field with no HoxD10-12 is still present in the rabbit foot, it is clearly larger in the bird wing, engulfing the PIDM of the anterior digital ray. Thus, comparison to the rabbit foot provides no support for the occurrence of digit 1 reduction in the wing.
What does this mean:
"Even if a small field with no HoxD10-12 is still present in the rabbit foot"

This sounds like a caveat. But luckily somebody thinks it is "clearly larger in the bird wing, engulfing the PIDM of the anterior digital ray." So do we laugh now?


This is a story on top of a story.
In fact they are not only looking at rabbits but rabbit FEET. And coming to conclusions about bird forelimbs. That is now a story on a story on a story.

Trump knows how to talk to kids, and Obamacare had apparently been in effect for 17 years...

Well, I'm glad the owner of a swingers B&B with zero education in the subject, has cleared all that up.
