That's pretty interesting. Using generic sequencing compared to other organisms, they're missing the sequences for torso and tail. Plus the sequences that are usually in front tub down the center of each arm.
Thanks for the TLDR
So is it one creature or a group of creatures?
One creature, they were just looking at where the genes expressed. There's a surprising amount of commonality in the DNA between animals, so they're able to look at where those common genes express on one vs another.
One creature that is all head.
Depends on how many chunks you slice them into...?
