4. You are looking at a series of rock layers and you want to survey the youngest stratum. How will you check 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 are told that it can be used for checking the relatedness between organisms. How would you go about determining these evolutionary relationships?

w5 apply. answer 4 and 5

1. You are observing an unknown vertebrate whose limbs are probably vestigial. What are the possible mechanisms 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. What vertebrate 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 is 5 000 years. You noticed that only 1/2 of the original amount is left in the rock layer. How old is the rock layer? 4. You are looking at a series of rock layers and you want to survey the youngest stratum. How will you check which one is the youngest without using absolute dating? 5.
