1.Explain the importance of the study of past environments in predicting the impact of human activity in present environments. Situations that occur in today's environment have happened in the past, so a close study of past environments leads to a knowledge of past environments and conditions which allows a better understanding of present-day ecosystems whic helps us to predict the human impact in present environments which leads to harmful practices being recognised and conservation projects. 2.…showed first 75 words of 642 total…

Extensive fossil record found at the Riversleigh site Queensland, revealed a large cross-section of organisms through time. Analysis of this site is proving extremely helpful in determining relationships between species.
