A lab activity evaluating the hypothesis that Earth's biosphere is currently undergoing a mass extinction, the so-called "sixth extinction." Students practice quantitative skills by calculating extinction percentages and rates in recent history using real-world data from the work of Ceballos et al. (2015). Then, they integrate modern and fossil data to see whether recent extinctions more closely resemble a mass extinction or the background rate of extinction in the fossil record. In the process, students critically examine sources of error and uncertainty and reflect on how to resolve them.
