If activationenergy required for a chemical reaction were reduced, what would happen to the rate of the reaction

In order to reduce the activation energy in a chemical reaction. a catalyst is introduced to lower the activation energy of a reaction, so that a chemical reaction can take place. However, by increasing the temperature of a reaction helps the effect in increasing the number of reactant particles that have more energy than the activation energy. Therefore, by reducing the activation energy, the reaction would go faster.

the fossil record provides evidence of a common ancestor to many species.
