Multicellular Life Evolves in Laboratory

Physics might be pure, but Biology is f<i></i>king amazing.<p>Makes me ponder my own place in the scheme of things - made up of many multicellular components, myself a component of a society, itself one of many that make up the Human species, one of many that form the ecology of this planet

Was this completely new, or was it some sort of latent ability that was brought out by environmental conditioning?

Is it "muliticellular life" or "multicellular" life (i.e. group of independent yeasts actually)?

This is wonderful. It is so simple, and takes a short enough amount of time, that it would make a fantastic lab experiment for high school students. Every day, remove the heaviest yeast and place it in a new environment and feed it. After 2 months, see that the yeast has formed into a larger organism.<p>If this is highly repeatable, it could have a great role for science education.

An honest question: aren't there potentially dangerous repercussions in breeding multicelular organisms like that? Could an innofensive organism become dangerous for us if it suddenly became more efficient and specialized?

If it was so simple to do in 60 days I wonder why they don't question the several billion years.
