Richard Goldschmidt although recognized the constant accumulation of small changes in populations (microevolution), he believed they did not lead to speciation. Between true species he saw "bridgeless gaps" that could only be accounted for by large sudden jumps, resulting in "hopeful monsters."
Goldschmidt tried to explore possible genetic mechanisms of how rapid change might occur in lineages of organisms. He suggested that a relatively small change might have a large effect on the phenotype, especially through "controlling" genes which mediate the expression of the organism's blueprint. Later, he thought macromutations or mutants (which used to be called "monsters") might arise in a single generation, and this biological novelty might enjoy a selective advantage under changing environmental conditions.

My personal opinion is that a slew of these fossils were found. Hence, the larger bone structure that resembles humans.
