Evolutionary biologist Sean Carroll introduces the field of Evo-Devo, using examples from fruit flies, butterflies, and icefish to explain how this research is transforming our understanding of evolution.

This short video would make an easy introduction to a unit on developmental genetics for an AP biology course.
Correspondence to the Next Generation Science Standards is indicated in parentheses after each relevant concept. See our conceptual framework for details.
- Present-day species evolved from earlier species; the relatedness of organisms is the result of common ancestry. (LS4.A)
- Features sometimes acquire new functions through natural selection.
- An organism's features reflect its evolutionary history.
- Similarities among existing organisms provide evidence for evolution. (LS4.A)
- Developmental similarities of living things often reflect their relatedness. (LS4.A)
- Scientists test their ideas using multiple lines of evidence. (P6, NOS2)
- Scientific knowledge is open to question and revision as we come up with new ideas and discover new evidence. (P4, P6, NOS3)
- Scientists use multiple research methods (experiments, observational research, comparative research, and modeling) to collect data. (P2, P3, P4, NOS1)
- Science is a human endeavor. (NOS7)
- Scientists use the similarity of DNA nucleotide sequences to infer the relatedness of taxa. (LS4.A)
- Scientists use developmental evidence to infer the relatedness of taxa. (LS4.A)
- Scientists use fossils (including sequences of fossils showing gradual change over time) to learn about past life.
- Environmental changes may provide opportunities that can influence natural selection. (LS4.B, LS4.C)
