2 when they are out of water the surface area of gills decreases because they are not very important when out of water when they are out of water they grow more blood vessels this is called angiogenesis. T turtles have a similar skull to extinct reptiles. C there is evidence of turtles being in position a,b, and c. Lu, b. , w. yang, q. dai, and j. fu. Using genes as characters and a parsimony analysis to explore the phylogenetic position of turtles. 7 supports that turtles are within the diapsida and that they share ancestor with birds and reptiles. Recent molecular evidence proposes that turtles are derived from diapsids. Thus, they would not be as ancient as previously thought. Most current data support c turtles are not at primitive as previously thought. K-t boundary cretaceous tertiary boundary (where many species went extinct, only some groups survived).
