SIMILARITIES:
Both the chicken and the human need a sperm and ovum to produce an infant or egg
The ovum needs to be fertilized before it becomes an embryo
Fertilization needs to occur inside the body of a chicken or human
DIFFERENCES:
Chickens produce an egg and the chick hatches outside the body, while humans carry the embryo inside the female's body and the infant hatches from the embryo inside the body
Roosters do not have a penis, but the male human does
Chickens lay more than 1 egg, while humans can only produce 1 baby at a time
Chickens do not have breasts and therefore do not feed milk to their young, but female humans do and breastfeed their young at birth
Humans carry the embryo for over 9 months, but chickens' eggs only take around 21 days to hatch
Human's unfertilized ovum becomes menstruation, but chickens lay their egg even though it's unfertilized
