Final answer:
Evolutionary developmental biology is a new science that looks deep into our genes. It focuses on how changes in genes during embryonic development have led to the evolution of different animal taxa.
Step-by-step explanation:
Evolutionary developmental biology is a new science that looks deep into our genes. It focuses on understanding how changes in genes during embryonic development have led to the evolution of different animal taxa. By studying gene sequences and their variations over time, evolutionary developmental biologists can infer the evolutionary history of life on Earth.
