82)Below are descriptions of four fictional female lizards. Which lizard might a biologist consider to be the most fit in an evolutionary sense? Lizard B   Lizard D   Lizard A   Lizard C

On a research expedition to the Galapagos, you and your research team discover four new species! All the animals appear to be chordates, but each animal has distinct traits: Animal A: Both vertebral column and jaws Animal B: Vertebral column, jaws, limbs and lays amniotic eggs (amniote) Animal C: Vertebral column Animal D: Vertebral column, jaws and limbs   A. Identify four derived characteristics that all chordates share. B. Based on your understanding of phylogeny, map the animals and their traits onto the phylogenetic tree provided below. In your response, list each number (1-8) and indicate which trait or animal corresponds to that position on the phylogenetic tree.

In the Figure below you can see an Aardvark (1), an Ant eater (2) and a Pangolin (3). Aside from size and fur, all share very similar traits in their body structures and diet (ants) despite not being closely related at all. Explain why those animals look alike

Examine the skeletal material at this station. What is the likely diet for each specimen? Keep in mind that a primate might have anatomy adapted for more than one food category.  (It helps to justify your answers. ).
