Niles Eldredge and Stephen Jay Gould researched the lenses of the eyes of fossil trilobites of different species. In 1972 they published a paper in which they described the tendency of a species to remain the same un5il a sudden change in the environment causes a new related species to appear.
Which hypothesis was most challenged by the work of Eldredge and Gould?
Redi's hypothesis that spontaneous generation does not occur
Haeckel's hypothesis that embryological development mimics the evolution of species
Wallace's hypothesis that geography affects the distribution of species
Darwin's hypothesis that the development of species is a slow, gradual process

This diagram of the fossil record represents changes in mollusks over millions of years.
How can the pattern of changes in the fossil record best be explained?
the mollusks were well adapted to their stable environment. A large sudden change occurred in their environment. After the changes, the mollusk with the bigger shells was better adapted to the new environment.
the mollusks were well adapted to their stable environment. the mollusks hybridized with a smaller species of mollusk. A new species of mollusk with a bigger shell resulted.
the mollusks were not well adapted to their environment. the length of the mollusk's shells changed gradually over time. The mollusks in the original population that has small shells died over a period of many years.
the mollusks were well adapted to their environment. humans introduced a new species of mollusk that was not adapted to this environment. the introduced mollusk outcompeted the native mollusk species.
