This exact experiment has been preformed recently, and the results were spectacular:

Single-celled yeast were subjected to selection pressures favoring multicellularity. In all 15 parallel experiments it took less than two months for the yeast to evolve into snowflake-like clusters. Within a mere two additional months this snowflake-yeast evolved striking uniquely multicellular traits. The yeast clusters displayed a fast-growth juvenile form leading into a non-growth adult reproductive form. They also exhibited cellular specialization, with specified cells committing suicide to enhance the reproductive capability of the multicellular entity.

Expertise

I can answer questions about evolutionary mechanisms and theory, including genetic drift, mutation, natural selection, etc. I also can clear up misconceptions about evolution as it's sometimes talked about by those not well-versed in the subject (e.g., some politicians and many religious fundamentalists).

Experience

I have a Ph.D. in Biology, and presently teach Evolution and Biodiversity, Genetics, Botany, and Zoology at the University of Miami.
