What species is Lucy and Selem (use the genus and species name)? What time frame did this species exist? Where did they exist geographically? Name one trait for this species that is more apelike and one trait that is more human like. What was the environment of the Rift Valley like when Salem lived there? Review the six models in the text (Ch 10) which work to explain the evolution of bipedalism. Which model do you think is the most likely explanation? Do you think there are likely several models that might have played a role in the evolution of bipedalism? Select one or more model and briefly state why you favor that model(s). Use data from the texbook and/or video. What is competitive exclusion (see text, powerpoint for definition)? Give an example of competitive exclusion between hominin species. How does the molecular time clock give us knowledge as to when species last shared a common ancestor? When did we last share a common ancestor with chimps?

in the united states today, there are numerous sources of law. the main ones are (1) constitutions—both state and federal, (2) statutes and agency regulations, and (3) judicial decisions. in addition, chief executives (the president and the various governors) can issue executive orders that have the effect of law.

in international legal systems, sources of law include treaties (agreements between states or countries) and what is known as customary international law (usually consisting of judicial decisions from national court systems where parties from two or more nations are in a dispute).

as you might expect, these laws sometimes conflict: a state law may conflict with a federal law, or a federal law might be contrary to an international obligation. one nation’s law may provide one substantive rule, while another nation’s law may provide a different, somewhat contrary rule to apply. not all laws, in other words, are created equal. to understand which laws have priority, it is essential to understand the relationships between the various kinds of law.
