You are studying the development of a poorly-understood species at the 8-cell stage. You use a laser to zap away a certain one of the eight cells, and discover that part of the gut is missing once the embryos finish development. Your colleague, who is working on a different species, uses the laser to blast away one of the cells in her embryos, zapping each of the possible cells in a set of eight experiments. However, when the embryos finish development, every one is perfectly normal! What can you conclude about the two species?
A. The first species has regulative development, the second has non-regulative development. B. The first species has non-regulative development, the second has regulative development. C. Both species have regulative development. D. Both species have non-regulative development. Clarify Question What is the key concept addressed by the question? What type of thinking is required?
