Shuffling nuclear distribution in embryos of this animal revealed a more probabilistic nature to blastomere differentiation in a study by Hans Driesch, who also used this animal to make the first-ever clone.
Sutton's work with grasshoppers and Boveri's studies on these organisms led to the chromosome theory of inheritance.

An Arbacia species of these animals produces the chemoattractant resact, and they ensure species-specific recognition using bindin. The acrosomal reaction begins on contact with the jelly coat layer first discovered on the eggs of these animals, whose use as a model organism for observing gamete fusion was popularized by Oskar Hertwig. For 10 points, name these spiny echinoderms used to study fertilization.
