During the scene with Amelia in the biology lab, Wei-Chen has an affinity to the teacher's lipstick-wearing monkey, who will not leave him alone. Wei-Chen can easily recognize that the monkey is actually a male, just as the monkey can actually recognize that Wei-Chen is a monkey himself.
Did the first vertebrates evolve during the mesozoic era? No. The 1st vertebrates appeared in the fossil record about 525 million years ago during the Cambrian Period.
âJawed vertebrates appeared 100 million years later, in the Silurian.â âOwen's studies on fossil vertebrates were immensely productive.â âIn short, this analysis finds that conodonts are more derived than any of the living jawless vertebrates.â
