It Is Not Weird Enough In Here: Insect Head Transplants

The entire process seems to have started in 1923, when a biologist named Walter Finkler reported that he had managed to successfully transplant the heads of insects. He’d been working with water boatmen, meal worms, and common butterflies – both in adult and grub form. The transplantation process was not complex. He’d grab two insects, cut off their heads with sharp scissors, and switch them. The fluid that the insects themselves leaked cemented the new heads in place. After a little time -- a 1923 article says a few weeks -- the insects were healed up and doing whatever their new heads told them to do. Finkler claimed that the heads of female insects on male bodies continued female behavior, and the head of one species of butterfly kept the habits of its own species, even when its body belonged to a different species.

Hey, its gets weirder:

Most disturbing of all, the brains don’t have to necessarily be added to the head part of the insect. While studying how certain moth pupae know when to turn into full-grown moths, researchers had a hunch that the pupae depended on getting through a winter first. This meant that the pupae had to be exposed to very cold temperatures, or at least their brains did. The scientists grabbed some moth pupae brains, chilled them down, and stuck them in the abdomens of pupae that had never been chilled. Sure enough, the loose brains started releasing hormones that causes the moths to develop. How they managed to go on with brains in their abdomens isn't discussed.

It is interesting, however it's more an issue of how simple insects are. They probably have lots of cellular or chemical cues that are handled by more complex nervous systems in higher orders of life.

It would never work for 90% of Chordates.

Pretty soon someone will be grafting multiple asses onto monkeys, or something.

Saveworks for those in Washington, DC.

If ye love wealth better than liberty, the tranquility of servitude better than the animating contest of freedom, go home from us in peace. We ask not your counsels or your arms. Crouch down and lick the hands which feed you. May your chains set lightly upon you, and may posterity forget that you were our countrymen.

Last time I checked, leaches are not considered Chordates.
I am free, no matter what rules surround me. If I find them tolerable, I tolerate them; if I find them too obnoxious, I break them. I am free because I know that I alone am morally responsible for everything I do.

Yes, but just like the occupants inside the Beltline, they don't have very sophisticated central nervous systems, either.   ;)
