Document Summary

1. place the skulls in order from oldest to newest. Explain two trends in features that allow you to do this. How do these skulls pose problems for the single species hypothesis: b, a, c. The protruding jaw from the oldest and from the newest skull, the face becomes flatter. The brow ridge becomes less dominant in the newest skull. Bonus: how would you write the ploidy and number of chromosomes in shorthand notation: metaphase ii kinetochores of sister chromatids are attached to microtubules from opposite poles, the ploidy of haploid, the chromosomes are replicated, n=2. 3. if you ever lived in an area where lizards are commonly seen, you have probably seen a lizard doing pushups , elevating the head or upper body in a series of jerky movements. We would like to investigate the circumstances for this. As you spend time watching lizards, you become more attuned to detecting their motion and observing their movements.
