You Can’t Always Get What You Want: A Lesson in Human Evolution

Julie Boehm
Biology Department
Wellesley High School
Wellesley, Massachusetts

This lesson introduces students to the concepts of evolution, specifically the evolution of humans. So often our students assume that humans are well adapted to our environments because we are in control of our evolutionary destiny. The goal is to change these types of misconceptions and get our students to link the concepts learned in their DNA, protein synthesis, and genetics units to their understanding of evolution. Students will also discover that humans are still evolving and learn about the traits that are more recent adaptations to our environment. The lesson is designed to take two one-hour class periods to complete. The activities will allow students to draw connections between environmental pressures and selected traits, both through data analysis and modeling. Most activities can be done without any special materials, although the Modeling Natural Selection activity needs either a tri-colored pasta, or tricolored beans, to be completed effectively.

 

本授業は、生徒に進化の概念、特に人類の進化の概念を紹介します。生徒たちは、人類が進化の運命を制御できているため環境によく適応していると思っています。この授業の目的は、そのような種類の誤解を解き、DNA、タンパク質合成、遺伝学の単元で学んだ概念を進化の理解に結びつけることです。生徒たちはまた、人間が今も進化していること、そして近年環境に適応した形質について学びます。この授業は、1時間の授業を2コマ受講することで完結するように作られています。生徒が、アクティビティの中でデータ分析とデータモデリングを通じて環境圧と選抜形質との関係性を見出せるようになっています。大半のアクティビティには特別の材料を準備する必要はありませんが、自然淘汰のモデリングを完全に行うには三色パスタあるいは三色豆が必要になります。

 

这节课给学生介绍了进化的概念,尤其是人类的进化。我们的学生常常认为人类很好地适应了我们周围的环境因为我们能够掌握我们的进化命运。这节课的目的就是为了改变这些误解,并且使我们的学生将这些在DNA, 蛋白质合成,和遗传学单元里学到的概念和他们对进化的理解联系起来。学生们将会发现人类还处在进化中,他们还会了解到人类为了适应我们的环境直到最近才进化产生的一些特性。这节课设计为两节时长一小时的课。课堂活动将通过数据分析和建模来让学生得出环境压力和选择特性之间的联系。大多数的活动不需要什么特殊的材料,但是,模拟自然选择过程的活动需要用到三种颜色的意面,或是三种颜色的豆子。
