Don't feel bad. You can always learn... you need not remain illiterate forever.

Physical sciences are amenable to direct observation and experimentation. Thus there are well defined laws and formulations that have been established over time. Gravity, electricty and atomic properties are examples.

Evolutionary paths and evolutionary relationships between organisms are juch more problematic and are not amenable to the same sort of direct observation as simpler physical subjects. It remains much more hypothetical compared with known properties of elements.
