After 30-40 cycles in Radcliffe's experiment, yeast evolved into snowflake-like, multi-fingered multicellular forms.

“buy about 30 or 40 such cyclists he found that the yeast had evolved and this is astonishing I have pictures of this in the book into these sort of snowflake like multi-fingered multicellular forms a really a new organism a multicellular yeast and what's interesting about them is that when he let them be by themselves so no more recollection no more sedimentation they continue to propagate as multicellular yeast”

“William Radcliffe is a professor um uh who studies this transition this evolutionary transition from single cell to multicellular organisms and he did this actually an extraordinary simple experiment and he sort of just thought about thought about it uh over Christmas uh with travisano his uh his advisor he said well what if we just take some yeast um and culture them and we um we basically uh allow them to grow and and so remember Easter single-celled organisms and we just collect the sediment so anything that's multi-celled is obviously going to sink to the bottom of a flask we collect the sediment and then we allow that sediment to grow again in another cycle of evolution so this is sort of Darwin in a bottle”
