By Miqu\u00e9la Thornton<\/strong><\/p>\n Due to a multitude of human-driven impacts, the Earth is experiencing a\u00a0biodiversity crisis. It has been referred to as the\u00a0Sixth Mass Extinction<\/a>, and scientists are examining similar events in the planet\u2019s geological past looking for clues in ancient ecosystems to help us solve present-day issues.<\/p>\n Current events have produced dramatic changes in the distribution of species, altering a region\u2019s time-specific ecosystem known as a biota, says\u00a0Simon Darroch<\/a>, assistant professor of Earth and environmental sciences. Darroch hopes there will be evidence of previous biota changes in the fossil record, such as undisturbed rock sequences that can place notable events and species to appropriate time periods. Yet, the extent to which biogeographic patterns or the distribution of animals can be preserved in the fossil record is not well understood.<\/p>\n
