One of the most striking pieces of evidence for Darwin's Evolution of Species was his observations of finches and how their beaks differed from island to island, depending on their primary food sources. So what would happen to the theory...

Find similarities in seemingly unlike organisms. The second instructional activity in a series of 12 builds the concept of a taxonomy and explores the use of a dichotomous key. Learners begin in part one by attempting to group a set of...

Students observe the two major developmental pathways (protostome and deuterostome). They analyze data regarding differences in nucleotide sequences and construct a phylogenetic tree. They observe the similar evolutionary history shared...

Students explore and explain how mutations in the DNA sequence of a gene may be silent or result in phenotypic change in an organism and in its offspring. They analyze how evolution and biodiversity are the result of genetic changes that...

Students evaluate the degree of chromosome similarity and difference between humans and apes. Students infer about the relationship between a human and ape based on similarities found.
