Students describe, measure and compare cranial casts from contemporary apes, modern humans, and fossil hominids to discover some of the similarities and differences between these forms and to see the pattern leading to modern humans.
One to two class periods.
Correspondence to the Next Generation Science Standards is indicated in parentheses after each relevant concept. See our conceptual framework for details.
- An organism's features reflect its evolutionary history.
- The fossil record provides evidence for evolution.
- Similarities among existing organisms (including morphological, developmental, and molecular similarities) reflect common ancestry and provide evidence for evolution.
- The fossil record contains organisms with transitional features.
- Evolution does not consist of progress in any particular direction.
- A hallmark of science is exposing ideas to testing.
- Scientists use multiple lines of evidence (including morphological, developmental, and molecular evidence) to infer the relatedness of taxa.
- Scientists use fossils (including sequences of fossils showing gradual change over time) to learn about past life.
