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

Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.
