the thing i love about social animals is they necessarily have a concept of manners which means that you can be rude to them. not threatening, but rude. and they’ll be annoyed at you for it.
One time I brought a haybale out to the horses, tipped it into their feeder, turned to walk away as they moved in, and then decided that well technically maybe the one horse had gotten a little too into my personal space on his way to the food. So I turned back around and tried to move him off. And he just gave me the most WITHERING look. Because no he didn’t, I had no leg to stand on, unassertive energy, L, etc
That one moment swore me off management positions for life.
does it indicate anything about me that I immediately recognized what paper this figure is from
so I had to immediately go and pull this other amazing figure from the paper, which is “THE HEXAGON” a device with six rooms for fruit flies to have sex in and a central room for a fruit fly to observe six couples having sex at once
Is the goal to see if being able to observe multiple options simultaneously effects the watching flies’ choices?
so the things about making decisions is that it takes a bunch of time and energy and brain power to gather and assess information, and it is evolutionarily advantageous to cheat and offload as much of the work as possible onto other people. thus, there is natural selection for observing other people’s decisions and mimicking them.
in a lot of critters, this means it is advantageous to watch who someone else picks for sex so you can copy what they decided was sexy when you select your own partner
the simplest version of the fly sex panopticon is basically just a 2-chamber tube where scientists can orchestrate sex shows for fruit flies.
(“watch a demonstration” is scientist code for watch anorthern pair of fruit flies have sex)
you can very quickly instill a preference: cover male fruit flies with pink or green fluorescent powder, and then let a female fly observe another female fly having sex with a pink male. the observer will conclude that pink is extremely sexy and be much more likely to select a hot pink male herself. by switching the colors and the learned preference to green, you can demonstrate that this is indeed learned behavior, and not some kind of pre-existing genetic preference.
the 6-way “sexagon” was invented for this paper to test how seeing different ratios of pink vs. green males being chosen would affect the development of preference.
the cool thing about this graph is it shows it didn’t matter if there were only slightly more of the the females picking pink or green males, the observer would still develop a preference for whatever the majority were choosing.
the whole paper is very cool, and absolutely worth a read:
it argues (and supports experimentally) that since preferences can be learned and passed on, fruit flies have an actual culture that can vary among populations and be transmitted to youngsters across generations.
this is super cool, because most studies proposing or examining the existence of culture in animals have been focused on higher level stuff like monkeys. if something as simple as a fruit fly can have a culture, this suggests that animal culture could have had huge effects on evolution from the ground up.
so yes, animal culture! fruit fly culture! very cool
but also an excellent evolutionary argument for voyeurism
