Gallus gallus (chicken)Keeping in mind that the Cambrian explosion happened about 550 million years ago, try and guess when the lineage leading to these species diverged from the lineage leading to humans. Check your guess on the website.
Danio rerio (some kind of fishy thing)
Strongylocentrotus purpuratus (purple sea urchin)
Drosophila melanogaster (fruit fly)
Caenorhabditis elegans (nematode)
Saccharomyces cerevisiae (baker's yeast)
Arabidopsis thaliana (flowering plant)
Plasmodium falciparum (protozoan, causes malaria)
Escherichia coli (bacterium)
Where you right? Why, or why not?
