When describing this experiment to your friends, they point out that rotifers are multicellular predators and thus cannot have been responsible for the earliest transition from single cell to multicellularity. Based on what you have learned in this lab and in the paper by Herron et al. 2019, what would be an informed response to this comment include? Select all that apply. Question 3 options: It is irrelevant that rotifers are multicellular in our study as some of the predators of small unicellular organisms are themselves unicellular, and predation, whether by a unicellular or multicellular organism, was all that was needed. Multicellularity evolved many times. While multicellular predators cannot have been responsible for the earliest transition from unicellular to multicellularity, they may have played a role in some of the later transitions which occurred after the evolution of animals. Using a multicellular predator is a major design flaw however no unicellular predators currently exist. The goal of the experiment was not to show that predation by rotifers is responsible for the origins multicellularity but rather that multicellularity may be an adaptation against predators in general.
