BUT required you to be able to assess the latter. SoTyrannosaurusbecame a “case study” for me in how to reconstruct form and function in extinct animals, because it was interesting in its own right (mainly because of its giant size and bipedalism). (Much later, in 2007, I finallyfinis...
What is the common ancestor of all animals? What group of dinosaurs does the titanosaur belong to? What are apes classified as? What are the smartest primates? What mammal lives the longest? In what epoch did the first hominids appear? What was the golden age of mammals? What major anima...
The elephant’s ancestor was one of the mammals that began to exploit the tropical coastline. Modern elephants retain much of their coastal heritage: they are impressive multi-mile swimmers; one theory even says the trunk first evolved as a snorkel! Some the elephant’s ancestors followed a dif...

whereas ostriches go the opposite direction and develop a giant double-boned kneecap in each knee (see below), whereas some other relatives like tinamous and kiwis develop a more “normal”, simple flake-like bit of bone, which is likely the state that the most recent common ancestor of all...
