Answer
Carbon atoms are very versatile in what shapes of molecules they can make, and, thus, what kind of information they can encode. Tn the case of the two lions pictured this means that different signals can tell male and female lion bodies to produce different structures, such as the mane, which the male has but which they female lacks.
