Today we have a second installment for Caturday—a great new tee-shirt featuring kittehs and science. It’s designed by Richard Smith, who produced two other shirts I’ve featured before.
You can buy “Science kitteh” here for only $20.44. Be sure to check out the title of the peer-reviewed paper.
If you’re myopic or presbyopic, the title is “Genetics and speciation”: the shirt was designed in my honor. Buy it NOW!
Thanks, Richard!
Hehe I really like those.
In case you haven’t seen it, you might also like this picture of a baby ocelot:

Pretty little predator ~ love the tail
I love that the paper is in authentic submission draft manuscript form.
Always assuming that the kitteh is not sitting on it to use it for kitteh littah.
Only puppies (and assistant professors) get “paper trained.”
The idea & execution is rather lovely. Plus it’s witty. Nice one.
I have to try real hard to see a nose there instead of a mouth. I see a “:D” cat. Anyone else?
Same ~ but that’s OK isn’t it?
No, I see a rabbit.
Ah – Necker cube etc…
No, I saw it immediately as a nose. So many years of looking at triangular cat noses…
I watched a Youtube of R. Dawkins outlining one of the chapters in his new book in which he pointed out that each immediate son/daughter of a pair of parents will, without question, be a member of the same species as the parents.
So how do we get different species — do I have to read your WHOLE(!) book to find out?
(I was a physics/meteorology major.)
Wait.
And read the goddam book.

You’re mixing up individual level with population level. Speciation and evolution are population phenomena. I haven’t read Coyne’s book, but I believe any book about evolution will explain this difference nicely.
You are thinking about one parent and one child. You can conceptualize that by simply drawing horizontal lines, one above the other. If you keep drawing lines, only one at a time and making sure each line overlaps with the one immediately above (the overlapping would mean they belong to the same species), then you’ll find you can’t get two species. Here. You can have each line shifted to the sides, which would mean variation inside the species. You could even find the last line you draw doesn’t overlap with the first; it would be an example of what’s called anagenesis.
However, if now you consider each line to be not an individual but different moments in time of a population (let’s say each line is 100 years later, and the lenght of the line would represent its amount of genetic diversity), you can see it’s very easy to divide a population. That’s what happened to Darwin’s finches; they went to live to different islands, and each group lost contact with their fellows on other islands (but that’s only one of many possible causes that can divide a population). So now you need at least two colors for the lines, since we’re considering two different groups. And then this can happen.
As long as everyone in the population is breeding among themselves, there can’t be much divergence because they balance each other. The red ones keep breeding with the blue ones, so you can’t really have red and blue, just some sort of brown who maybe gets somewhat reddish or bluish from time to time. Once you have isolated groups, those groups can diverge in different vectors, to the point of being so different they can’t breed with the folks on the other group anymore.
The process of evolution doesn’t give a christian god’s nails about no stinking species. Species is a human construct to aid in pointing to a specific part in the mesh of organisms.
Now go get your big box of crayons. No! Not the little 512 crayon box, get the 64,000,000 crayon box. Yes that’s the one. Dump all the crayons out of the box, yes, even that ugly god colored one, and mix them around. Now sort each crayon into either a red, green, or blue group. Don’t make any mistakes for that will cause the christian to claim its god created the colors as you weren’t able to complete the task with precision. When finished, you should have an idea of what a species is if you imagine each colored wax stick to be a crayola offspring and also a potential dividing line for the red, green, or blue species.
Have fun and don’t forget to bray about it.
Being well read is sexy so you’ll help your genes to jump upstream if you crack a few books & feed your brain! You’ll be getting laid, having fun at parties, perpetuating your little DNA robots & supporting Jerry Coyne’s boot addiction ~ that’s a win win win
The definition of species is fuzzy. A group of animals may all be capable of interbreeding & producing viable offspring that are fertile & yet that group could consist of more than one species.
Here’s an educational thread from over at the RDF How to refute creationist nonsense on transitional species by SCHRODINGER’S CAT. Plenty of grist in there.
