"The fossil record does not support this . So , in an attempt to deal with this problem , Gould and Eldredge came up with a theory called , punctuated equilibrium ."
"Actually , the fossil record does support it . Both Eldredge and Gould have discussed it . Both men made observations of slow gradual speciation in the fossil record in a small geographical area . These changes were reflected at other locations as an abrupt change from one species to another . But given that such changes take place very quickly in populations that are usually under environmental stress and isolated from the main population , and given the rarity of fossilization in the first place , we do n't expect to find many examples in the fossil record . It is a bit like trying to time a 100 yd . dash with a sundial . The fossil record just is n't fine grained enough to see the rapid ( 50-60 thousand years ) changes ."
