I’ve watched at least half a dozen long presentations and interviews from dr levin and I’d say the previous commenter is essentially repeating it exactly how Levin describes it. To be fair it’s not exact. What I understood from the interviews is that they have been imaging bioelectrical activity in organisms during development and claim to have deciphered patterns associated with growth of certain structures. He talks about a certain ion channel drug (one used for epilepsy I believe) which they used to reproduce the bioelectric field previously observed and the organism grew a leg. Multiple legs actually, wherever they wanted. Also working eyes on arbitrary locations.

So from a high level they say they have figured out how to “speak” to cells in a sense and instruct them to start building certain structures. And they emphasize that they aren’t making any changes to the genome or manage any of the low level processes themselves.

Unless you can point me to some succinct papers or summaries, I'm going to continue with my believe that the dog wags the tail, not the other way around.
