How Zebra got its stripes.

[Indian]

Zebra’s stripes stave off blood-sucking insects.

‘We conclude that zebras have evolved a coat pattern in which the stripes are narrow enough to ensure minimum attractiveness to tabanid flies’, says the team and they add, ‘The selection pressure for striped coat patterns as a response to blood-sucking dipteran parasites is probably high in this region [Africa]’.

Anthony Zerbe has stripes?

That's pretty interesting!

REad it on the BBC, where an expert was saying it's far from conclusive

Prof Matthew Cobb, an evolutionary biologist from the University of Manchester pointed out that the experiment was "rigorous and fascinating" but did not exclude the other hypotheses about the origin of zebras' stripes.

"Above all, for this explanation to be true, the authors would have to show that tabanid fly bites are a major selection pressure on zebras, but not on horses and donkeys found elsewhere in the world... none of which are stripy," he told BBC Nature.

"[They] recognise this in their study, and my hunch is that there is not a single explanation and that many factors are involved in the zebra's stripes.

That's OK, most people don't notice anyway.


For those playing at home, the original title spelled it "Zerbra"

I heard one of the study authors interviewed on NPR today.

Then it should follow that zebras and dark-colored animals have significantly fewer illnesses and diseases from horseflies and related insects, right? That never came up, so I remain unconvinced.

Just so, and how did the camel get its hump? the leopard his spots? ;)

Somebody roofied its dram o'dairy.
...the leopard his spots? ;)
Adam was walking through some thickets in the Garden of Eden. He parted some vegetation and saw a large jungle cat. When he got home, Eve asked him about his day. He told her he spotted a leopard.

They got those things Just So (http://boop.org/jan/justso/) of course!
Surely I can't be the first to note the Kipling reference. (ETA: I mean, the first after Chela, who obviously got it.)
(Or am I just being a d00f for being the first to say so?)

It must be 45 years since I read those stories!

(Did Kipling have anything to say about Zebras? Or Anthony Zerbe?)

I thought that would apply to the zebra stripes as well, but thanks, I learned something today.

This new research on Zebras is very surprising.Whether the" flies" theory gets wider acceptance from other scientists is an open question.

[brittekland]

Yes, I'm not so sure I'd accept developing stripes on myself just to get away from mosquitos even though I truly hate them bastards... but then I'd think mosquitos probably would require different pattern... :dubious: ;)

I got my stripes during the Campaign at Carthage. I was a lowly corporal but command feel to me when the Lt. was taken down by a sniper. I held the hill for 36 hours without relief against a numerically superior force and was promoted to Sargent.


That's how I got my stripes.
