Observation:

there is a dick &: balls flapping between his legs so insemination can occur after penetration and subsequent fertilization to produce offspring

Hypothesis:

Males have a dick and ball flapping between their legs and use that to inseminate after penetration and subsequent fertilization to produce offspring

Test:

check all mammals for dicks and balls flapping between their legs and use that to inseminate after penetration and subsequent fertilization to produce offspring

Produce statistical analysis: 99.9999999% of the mammals use their dicks and balls flapping between their legs and use that to inseminate after penetration and subsequent fertilization to produce offspring

Conclusion:

All mammal males have dicks and balls flapping between their legs and use that to inseminate after penetration and subsequent fertilization to produce offspring.

Question:

how do you test whether a mammalian is male or female? check for dicks and balls flapping between their legs and use that to inseminate after penetration and subsequent fertilization to produce offspring

No dicks and balls flapping between their legs and use that to inseminate after penetration and subsequent fertilization to produce offspring?
