Can evolution create new species over time through natural selection?
is the question he would be prompted to ask based on his voyage.
<h3>Who was Charles Darwin ?</h3>
- English scientist Charles Darwin gained notoriety for his theory of natural selection, which postulated that organisms in an ecosystem adapt and evolve in order to maintain their survival.
- Because of this, Darwin was inspired to consider whether natural selection can eventually result in the emergence of new species after studying the selective breeding of pigeons.
- Darwin came to the following conclusion based on these straightforward observations:
- In a population, some individuals would have hereditary qualities that assist them survive and reproduce (given the conditions of the environment, such as the predators and food sources present).

Which is true about enzymes is: enzymes increase the rate of reactions by lowering the activation energy barrier.
Enzymes are chemical compounds in the form of proteins that act as biocatalysts which function to speed up reactions.
Enzymes work specifically, that is, they can only work on certain substrates by adjusting the shape of the substrate. Enzymes sensor with molecules for substrates to produce compounds through organic chemical reactions that require energy. Some of the reactions assisted by enzymes such as the breaking of large molecules into small ones or the binding of molecules into new molecules. Enzymes can do that because of the influence of the activation energy that every chemical reaction has.
Activation energy is the energy required to break down the reactants. The role of enzymes is to lower the activation energy limit needed to start reactions.
