- The phylogenetic tree for vertebrates depicted below was constructed from sequence data for two rRNA mitochondrial genes (12S and 16S). How do the results of this analysis compare with the phylogenetic trees in Figures 32.10 and 32.24? Identify the major clades of vertebrates on the tree depicted below. Source: R. Zardoya and A.

- What role do the fossils named “Ardi” and “Lucy” play in the reconstruction of human evolutionary history?arrow_forwardBiologists have studied many different species, including humans, and have estimated that it takes500,000 years for 1% of the mitochondrial DNA to be changed by mutation. (This is an estimated mutationrate, and is currently being debated). Given that rate of mutation, we can estimate how long two groupshave been reproductively separated by multiplying 500,000 years by the percentage of difference. (If thegroups are 0.3% different: 500,000 x 0.3 = 150,000 years)A representative sample of different human geographical/racial DNA has been collected and analyzed.When all of the different mutations were counted, scientists found that only 0.4% of the DNA of modernhumans has been mutated. How many years have modern humans been on the planet?Archeologists have found skeletal evidence of a modern-type human who lived on this planet about100,000 years ago. You will investigate a partial answer to these questions.Two important questions we will be addressing in this part of the lab are:1) Where…arrow_forwardWhat two pieces of evidence support the claim that all life on Earth descended from a common ancestor?arrow_forward
