My Notes on Massive Open Online Course:
Paleontology: Early Vertebrate Evolution
This course examines the evolution of major vertebrate novelties including the origin of fins, jaws, and tetrapod limbs. Students also explore key Canadian fossil localities, including the Burgess Shale (British Columbia), Miguasha (Quebec), and Man On The Hill (Northwest Territories).

2 Vocabulary Words I Learned in this Course:
clade, n. From the Greek κλάδος ("branch"), a group of organisms that consists of a common ancestor and all its lineal descendants. Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently.  "Humans, other mammals, reptiles, birds, amphibians, and fish are all part of a large clade of animals called the vertebrata, or vertebrates."
homology, n. From the Greek ὁμός ("same") and λόγος ("relation"), the existence of shared ancestry between a pair of structures, or genes, in different taxa, a shared ancestory between two or more different features or traits in different organisms.  ""A common example of homologous structures in evolutionary biology are the wings of bats and the arms of primates.""
