fill out the table for each of the following as they relate to the fossil record: vocabulary definition image gradualism punctuated equilibrium stasis staar practice scientists can use the fossil record to determine changes in an environment. what does the abrupt appearance of new organisms show? move the correct answer to each box. the age of fossils an increase in biodiversity stasis transitional fossils gradualism an unstable environment the abrupt appearance of new organisms is evidence of and complete the sentence:

Explanation:

Gradualism is the idea that species evolve slowly and steadily over time. Punctuated equilibrium proposes that evolution occurs in short bursts of rapid change followed by long periods of stasis (little or no change). Stasis refers to a state where a species shows little morphological change over long periods. The abrupt appearance of new organisms is evidence of punctuated equilibrium and an unstable environment as new species often arise when environmental conditions change rapidly.
