Original sentence: Gould developed his theory of punctuated equilibrium, which sought to explain these lacunae in terms of comparatively long periods of genetic stability separated by periods of rapid evolution; this is still, however, a rather controversial theory, and despite the gaps in the fossil record very few people within the biology field take the anti-evolutionist view that there are no transitional fossils at all.However, some argue that the the many gaps in the fossil record that do exist are evidence that cuts against the theory of evolution.In addition, the fossil record of the ancestors of the modern horse and zebra as mentioned above is considered one of the best examples of a clear transition between species, the rationale being that while the ancestral Hyracotherium and modern Equus species are vastly different, there is such an abundance of intermediate forms that a clear transition between species is considered self-evident.It is a matter of record that there are substantial gaps in the fossil records; this is one reason Stephen J
Edited sentence: Gould developed his theory of punctuated equilibrium.However, some argue that the overall lack of convincing examples is evidence that cuts against the theory of evolution.The lack of transitional fossils in the overall fossil record is one reason Stephen J.This is one reason that opponents argue that the fossil record does not support evolution, but is rather something that needs to be explained away
