Answer:

Burgess Shale has the best record we have of Cambrian animal fossils. The locality reveals the presence of creatures originating from the Cambrian explosion, an evolutionary burst of animal origins dating 545 to 525 million years ago. During this period, life was restricted to the world's oceans.

The two graphs shown here represents a reaction that proceeds without an enzyme (left) and without an enzyme (right). According
nignag [31]

The  role of enzymes in a chemical reaction is to : Lower the activation energy while increasing the rate of reaction

The graph shown on the left is an uncatalyzed chemical reaction while the graph on the right is a catalyzed chemical reaction.

Catalyzed chemical reactions have lower activation energy and a faster rate of reaction while uncatalyzed chemical reaction has a higher activation energy and a slower reaction rate. because catalyst increases the rate of a chemical reaction by lowering its activation energy.

Hence we can conclude that The  role of enzymes in a chemical reaction is to : Lower the activation energy while increasing the rate of reaction
