The beginning of this two-week unit introduces evolution using bacteria and antibiotic resistance as anchoring phenomena. The following lessons demonstrate how species can change over time due to external, selective pressures. Based on the evidences of evolution (DNA, homologous structures, fossils, etc.) and from seeing evolution occur (e.g. bacteria evolving antibiotic resistance), students will be able to explain the diversity of life seen on earth today. This unit ends with students applying the knowledge they gained from the lessons on bacteria to a population of birds. The birds are subjected to different weather events that cause some traits to be more suited to the conditions created.
