Human Prehistory 101: Prologue. Chromosome Connection | Becoming Human. Comparison of Human and Ape Chromosomes <p>This site requires Javascript, please update your browser... </p><p></p> Students are taken on a chromosome comparison "adventure", in which the banding patterns are compared on the chromosomes of humans and apes. Degrees of similarities, and some causes of their differences are explored. Inferences about relationships based on those similarities are also examined in a compelling way. Main Concepts The degree of chromosome similarity between two species indicates the degree of their biological relationship.
Assessable Objectives Students will... actively engage in the careful analysis of chromosome banding patterns.identify examples of inversion in homologous chromosomes.demonstrate their understanding that degrees of similarities in chromosomes correspond to degrees of evolutionary relationship.associate degrees of similarity with relative timing of evolutionary divergence.

Interactive Documentary | Becoming Human. Becoming Human is an interactive documentary experience that tells the story of our origins. Journey through four million years of human evolution with your guide, Donald Johanson. Transcripts are available in the following languages: English, Spanish, Italian, Chinese, and Sinhala.

Primate Bipedalism: Understanding Standing Up <p>This site requires Javascript, please update your browser... </p><p></p> Anthropologists and evolutionary biologists agree that upright posture and the subsequent ability to walk on two legs was a crucial major adaptation associated with the divergence of the human lineage from a common ancestor with the African apes. Efficient upright walking required numerous changes in the anatomy of the limbs and pelvis and we are the result of the variations and selection pressures that forged this new ability.
Main Concepts Human evolution is marked by a mosaic pattern. Assessible Objectives Students will... identify key anatomical similarities and differences between the great apes and humans.infer likely anatomical features in ancient human ancestors.list principal anatomical changes in primates necessary for adaptation to fully bipedal locomotion.sequence particular anatomical features in hominids as part of a series of broader evolutionary trends.
