Lactating shemales ? Camera trick or real ?

[sesame]

After millions of years of evolution why do male mammals still have nipples?

Do you seriously want nipples in males to become extinct?
Besides, Homo sapiens came into being 400,000 - 250,000 years ago. Not even 1 million years!
Male and female only become different inside the mother's womb at a certain phase of foetal development. Before that they are the same. So, man and woman have the same organs with certain transformations.

Adult Female: fat under nipples
male: no fat, more muscles.

female: Broader pelvic bone for bearing children
male: small pelvis.

Female: ovaries
male: testes (the same homologous organs become ovaries in female and testes in male)

female: clitoris
male: glans of penis

female: Labia majora
male: scrotum

Female: Uterus
male: Prostate gland
