摘要

Organisms have increased in complexity through a series of major 演化ary transitions, in which formerly autonomous entities become parts of a novel higher-level entity. One intriguing feature of the higher-level entity after some major transitions is a division of reproductive labor among its lower-level units in which reproduction is the sole responsibility of a subset of units. Although it can have clear benefits once established, it is unknown how such reproductive division of labor originates. We consider a recent 演化 experiment on the yeast Saccharomyces cerevisiae as a unique platform to address the issue of reproductive differentiation during an 演化ary transition in individuality. In the experiment, independent yeast lineages evolved a multicellular "snowflake-like'' cluster formed in r
