That same Michael Levin once used his discoveries to make a tadpole with an eye somewhere near the gut. The eye formed correctly and grew a nerve that connected to the spinal cord. The tadpole was able to see out of that eye. It&amp;#x27;s definitely a non-stock configuration yet it worked. I&amp;#x27;m sure it&amp;#x27;s much more complicated than having 4 arms.</text><parent_chain><item><author>keyle</author><text>This implies that your brain could handle 4 arms.

Parthenogenesis could become a choice. Another head seems possible. The limits are more likely to come from regulation than a reluctance of people to transform themselves.</text></item></parent_chain></comment><story><title>How bioelectricity could regrow limbs and organs</title><url>https://news.uchicago.edu/how-bioelectricity-could-regrow-limbs-and-organs</url></story>

You can&amp;#x27;t just slot a ball and socket somewhere into the side of your ribs (and all the supporting musculature) and have it work the same way.</text><parent_chain><item><author>keyle</author><text>This implies that your brain could handle 4 arms.
