Snickerdoodles with Chipperdoodles
Jem Godfrey - Eat 17th April Mix
142 plays


First one off the press. Not quite finished yet, but near enough. Just so’s you know this all hasn’t been a ruse and I’ve been actually on holiday since February 1st.

Better late than never and all that…

I plan to get Lights Out, Concrete and Worn Words done this weekend too.  

Song mixes eh? They’re like bloody buses…

Party Tip #18

Don’t forget to take advantage of “multipurpose dance moves”.  Why not mesmerize the overwhelming bathroom line with some smooth moves while you skip to the front of it?  You’re bad, you’re bad- you know it.

FanWork Fridays: Will it Blend?



We posted about this earlier on Facebook and Twitter, but Space_Scumbag was kind enough to upload the full video of one of the weirdest, most innovative builds we’ve ever seen. That leaves us with the question - will it blend?





While out camping I noticed a red ant scurrying around and then dig up a dead bee that was hidden in the sand. It was really neat, I would have never noticed that bee so it was cool to see the ant sniff it out. I decided to try some macro pictures (I’ve never really tried to take buggy pics before). So I took a bunch of the ant trying to break apart the bee. It was neat.

Location of these is Joshua Tree National Park in California.

Make sure to leave yourself plenty of space for more “extreme” dance moves


everyone please watch this kc green animation

Well then… isn’t that nice?

Hello. Since you're the only science tumblr I follow I thought I would ask you this question. If an interracial couple were to marry, and have children, and their interracial children had interracial children, and so on, how many generations would it take before either the maternal or paternal ethnicity would be completely eliminated? (i.e. if it was a black and white couple and their mixed child married an asian, and their mixed child married an hispanic, and so on.)


Hi there! Thanks for your question. Unforch, this question isn’t really answerable.

Ethnicity and race are social constructs, not useful genetic traits that we can (or should) use to differentiate people. Ethnicity and race can’t “dilute” out (in a genetic sense), because you can’t point to a genome and say “that’s the Hispanic gene” or “There’s the sequence that makes you Asian.” Yeah, we can point to genes that influence skin color or facial features, but that’s not race. It’s biology.

That doesn’t mean that we can’t track genetic differences based on geography and its associated populations, though. We can, and we do. For instance, if we compared the genome sequences of indigenous North, Central and South American populations to, say, Asian and European genome sequences, we would see that the original Americans are more closely related to Asian populations. This matches up to geological studies that suggest that there once existed a Siberian land bridge, and allows us to make hypotheses about human migration patterns across the Earth (not all of those migrations have been voluntary, mind you). 

We can, and have, done the same analysis by comparing modern and ancient samples from place X with modern and ancient African DNA, which is how we know that we the first members of our species left Eastern Africa about 70,000 years ago to settle the four corners of the Earth (which has no actual corners, of course). 

However, like quick-drying cement, this analysis gets really hard, really fast (insert your own dirtier joke there if you like). Genetic fingerprints get jumbled thanks to the huge amount of genetic crossover that happens as part of our meotic sexytime, and because humans have interbred … a lot. Not in a gross (and genetically dangerous) “banjo player in Deliverance” way, but in a “we’re all related” way. We only have to go back 2,000-4,000 years before we find a person who is a common ancestor for every single human alive on Earth, and, for Europeans at least, anyone who was alive and had children 1,000 years ago is the ancestor of every person of European descent alive today

So it only takes a few dozen generations before analysis of our crossed-over, interbred nuclear genomes gets so messy that we’re tracing complex statistics instead of neat and tidy family trees. So to make it easier, instead of nuclear genomes, we often compare the tiny, circular genomes that persist within our mitochondria.

You’ll recall from biology class (you were paying attention, right?!) that our mitochondria used to be free-living bacteria, complete with circular, prokaryotic genomes. While most of that ancient genome has disappeared (or migrated to our own nuclear genome), our cellular energy factories still hold a circle of DNA that gets passed down to baby mitochondria when a cell divides and when a mommy and daddy lie down (or stand up, or whatever page of the Kama Sutra they’re on) and do Grown Up Stuff™. What’s weird is that (probably because eggs are big and sperm are small) every one of your mitochondria came from your mom, not your dad.

By comparing mitochondrial genomes from the past with mitochondrial genomes from around the world today, we are fairly certain that one single female of the Homo sapiens crew, living in Africa about 100,000-200,000 years ago, is the ancestor of every living human being today. We call her Mitochondrial Eve. She wasn’t the only human female alive then, and she wasn’t the only human with mitochondria. She’s just the one whose kids ended up covering the Earth.

Yeah, people whose recent ancestors come from South Asia look different from people whose recent ancestors come from Sweden. But that’s just human genetic variation, the same way that I have blonde hair and my friends Jamie and Eric are orange-haired gingers. 

People have grouped together (and often excluded other groups) throughout history for a variety of reasons, some of them good, and many of them unthinkably horrible. Because of this, our ancestors often bred with those close to them in geography as well as culture, reinforcing bits of human genetic variation in traits like skin color and facial features. We invented “race”. Evolution just made different kinds of people.

All of this is a long way of saying that while your original question doesn’t have an answer, studying genetic differences based on geography and culture is still important to science. Not because it shows us how we are different, but because it highlights our human connections, and reminds us of our shared experience and common origin in a world that could always use a bit more of that kind of thinking.


Gearing up for a new full length Lemon Demon album. In the meantime, I combined various singles from the last few years into a damn Bandcamp EP!!
