4. A study of palaeontology and past environments increases our understanding of the possible future range of plants and animals Explain the importance of the study of past environments in predicting the impact of human activity in present environments: • The knowledge gained from palaeontology (fossils) and the study of past environments can help us to understand present day ecosystems • This knowledge can be used to predict and determine the future for Australia’s plants and animals • Palaeobiologists

numerous class Pyrenomycetes or flask-fungi. The natural habitat of the three species of Sordaria that have been the principal subjects in genetic studies is the dung of herbivorous animals. The species S. fimicola is common and worldwide in distribution. The species of Sordaria are similar morphologically‚ producing black perithecia containing asci with eight dark ascospores in a linear arrangement. These species share a number of characteristics that are advantageous for genetic studies

of large pollen mother cells in each sac that are all diploid. The wall thickens in each pollen grain and forms an inner layer called the intine and an outer layer called the exine. Surface patterns are different on pollen grains from different species. After pollen grains have matured‚ the anther dries out and splits open‚ which releases the pollen. This process is called

they are not the same species. Definition of Species • A species is a group of interbreeding organisms that produce viable‚ fertile offspring in nature. • Members of a species will interbreed with one another but not other organisms outside of the species. (At least most of the time!) Macroevolution vs. Microevolution • Macroevolution is evolution on a scale of separated gene pools. • Macroevolutionary studies focus on change that occurs at or above the level of species‚ in contrast with microevolution
