Question

scientists can use the fossil record to determine changes in an environment. what does the abrupt appearance of new organisms show? (move the correct answers to each box.) the abrupt appearance of new organisms is evidence of and the age of fossils an increase in biodiversity stasis transitional fossils gradualism an unstable environment

Explanation:

The abrupt appearance of new organisms in the fossil record can indicate significant environmental changes. One such change is an unstable environment. In unstable environments, there can be rapid shifts in ecological niches, leading to the sudden emergence of new species as they adapt to these changing conditions. Another related aspect is stasis. Stasis refers to a period of little or no evolutionary change. However, when an unstable environment occurs, it can disrupt this stasis. The combination of an unstable environment and the disruption of stasis can result in the abrupt appearance of new organisms.

Answer:

an unstable environment, stasis
