This lab activity is a paper fossil dig where students discover skeletal characteristics of humans, primates and hominids and are asked to make a short oral presentation to the class.

In the engage section of the 5Elesson, students are introduced to the role of fossils as evidence of evolution and evolutionary relationships by watching a videos about the discovery of Lucy and Ardi and consider what type of information that they can gain from skull fossils. Students will then explore features of skulls from human ancestors and the modern day Homo sapien. After measuring skull to cheekbone ratios, students will create a graph to compare various species. Several interactives are provided to explain fossils, skeletal evidence for human evolution, and phylogenetic trees. Then, students will apply their skills of analyzing data about anatomical similarities and genetic information to depict evolutionary relationships between organisms using cladograms. To evaluate student understanding, students will complete an evolutionary relationships CER.

Introduction to Paleoanthropology covers the various species and subspecies that gave rise to human beings. Paleoanthropology is a subdiscipline of physical anthropology that focuses on the fossil record of humans and non-human primates.

In this biology activity, students will first brainstorm how humans use their hands. They will then conduct a short experiment to determine the importance of the opposable thumb to humans and how it is an important adaptation.
