What type of molecule is best suited for identifying the specimen? DNA Can you take a guess here at which of the following animals is the closest relative to the carcass we saw in Cambodia? White shark Which pair of structures is NOT homologous between humans and whales? Human legs and whale tails Have a look at the skeleton of a whale. Which structure is homologous to your leg? 2 Why are these structures so similar? The animals share a common ancestor. Use this image showing the wings structure of different animals to help you determine which of the statements is true? Bat wings are analogous to bee wings Which of these animals appears to be the most closely related based in this sequence? Blue whale Make a guess, which of the following animals is most closely related to whales? Seal Have a look at the following phylogenetic tree. Which statement is true. Branching points stand for the common ancestor of two diverging groups Was your hypothesis right? Which of these animals share the most recent ancestor with whales? The hippo is the closest relative Which of the following statements is true? All living creatures share the same single-celledancestor Take a look at the alleles in the first generation of offspring, the F1 generation. What percentage of alleles are passed on from the original mother and father? 50% from each parent Does the allele frequency of the whole population compared to the founder population change? The allele frequency stays the same Which of the following phenomena could disrupt this equilibrium? All of these Why does the population continue to grow exponentially? The carrying capacity has been reached Which statement about frequency of yellow A1 allele is true? The allele frequency has changed from the initial population Which evolutionary force leads to these allele frequency changes? Natural selection In relation to natural selection, evolution is the... Mechanism Which of the following sentences is compatible with the idea of the survival of the fittest? Natural selection weeds out individuals that are unfit It looks like Charle's allele persists at a low frequency within the population. What property of the population has increased as a result of the viable mutation? Genetic variation It looks like 100 years after the climate on the island changed, the entire population carries Charle's gene. What is this phenomenon called? Adaption
