During the 17 th and 18 th centuries, these primitive doctrines were refined into a scientific school of thought called preformationism, which held that living beings were essentially fully-formed prior to conception.
Structure and Function of Molecules and Cells (revised 9/2014)
This analysis and discussion activity helps students to understand how biological communities change during succession after a disturbance. Students analyze research evidence and explore how the interactions between different types of plants and animals influence succession. Students use their understanding of the processes involved in succession to construct and evaluate models of succession in abandoned farm fields. Students also analyze the effects on succession of climate and non-native invasive plants. (NGSS)
That is fulness to overflowing.
In this activity, students analyze evidence from comparative anatomy, mathematical modeling, and molecular biology. This evidence suggests a likely sequence of steps in the evolution of the human eye and the octopus eye. General concepts used to interpret this evidence include natural selection, fitness, and the difference between homology (similarity due to common descent) and analogy (similarity due to convergent evolution). Optional additional questions presented in the Teacher Notes can be used to discuss topics such as the contributions to evolution of gene duplication and mutations in the regulatory DNA sequences that control gene expression.
