Everywhere you go on this planet—on land, underground, in the air, and in the water—you’ll find life that has been shaped by evolution. In NOVA’s Evolution Lab, you will explore the evidence of evolution through the lens of phylogeny.

The Evolution Lab contains three main parts, last part being the assignment submission:

A- Build A Tree: Includes 7 short videos and 6 missions (Links to an external site.)

1-Begin your exploration by watching the introductory video entitled “Evolution 101” for an overview of evolution, going back to its discovery by Charles Darwin (and Alfred Russel Wallace, just a little late to the party). Then you’ll be ready to put your understanding to the test by playing our version of the game of life.

2- Go to each of the missions and complete the game. Watch the videos for each mission

You have to build phylogenetic trees themed around the evidence of evolution, including fossils, bio-geography, and similarities in DNA. You use both morphology and analysis of DNA sequences to identify relationships between species and to organize species and traits into phylogenetic trees. Along the way, you will watch seven videos that introduce the missions and give context for how the theme of each mission helps us understand how evolution has shaped life on Earth.

B- Deep Tree: (Links to an external site.)

Once you’ve learned how to create trees that capture the evolutionary relationships among a handful of species, you’ll be ready to enter free-play mode to conduct your own investigations in our virtual tree of life. Deep Tree contains information about more than 70,000 species, with detailed descriptions of 200, spanning the 3.5-billion-year history of life on Earth. And it allows you to relate any two species to identify their shared traits and trace their evolutionary lineages back to when they last shared a common ancestor.

C- Assignment SUBMISSION

To complete this assignment you must submit a screen shot of the complete Lab report.

It should looks likes something like this but will at least 4 of the missions complete:
