The study of artificial selection by Darwin helped him to establish his theory of evolution via natural selection. One of the animals Darwin examined in detail was the domestic rock pigeon. In the 1850s breeding of pigeons was an ancient past time, thus, Darwin decided to keep and breed the pigeons by himself.
While studying pigeons, Darwin established scrupulous determinations of their skeletons and wondered at the breeds' distinct colors, behaviors, and proportions.

During pregnancy, the active component of cannabis, which is THC (tetrahydrocannabinol), can go into the placenta and affect the fetus, including its birth weight (like the case in the question here) and brain function, reducing the baby's IQ and attention capacity.
Depending on the type of drug and the quantity consumed, it is also possible that the baby suffers from weaning at birth, that is to say from deprivation (inconsolable crying, irritability, tremors, feeding difficulties, etc.). .
Cannabis may also have longer-term effects in children (learning disabilities, behavioral problems, hyperactivity, etc.).
