w5 apply. answer 4 and 5 1. You are observing an unknown vertebrate whose limbs are probably vestigial. What are the possiblemechanisms of locomotion that this organism can have?2. In relation to your previous survey of tetrapod limbs, you are also aiming to look at their origins. Whatvertebrate groups should you be looking at? How should this group then be studied?3. You are surveying an area's rock layers using absolute dating. You have an element whose half-life is5 000 years. You noticed that only 1/2 of the original amount is left in the rock layer. How old is therock layer?4. You are looking at a series of rock layers and you want to survey the youngest stratum. How will youcheck which one is the youngest without using absolute dating?5. You are given the sequences of amino acids for a certain polypeptide for different animals. You aretold that it can be used for checking the relatedness between organisms. How would you go aboutdetermining these evolutionary relationships?
