so can someone tell me why when a man does it with a horse or a camel or cow
or a pig why can that sperms not become fertile into the other animals egg and create a new life form?

also has it been tried for a mans sperm to be put into a reptile like an alligator to see if that could have a different effect?
or maybe it could be tried on a mammal like a dolphin that are said to be relatives of the human race.

this could be a good scientific experiment.
tell me what you think.

cuz we are different species, it doesnt work

Well that is obvious but really. How did humans become a human???
If we are so different then how did we come from other species on the planet?

I was eating but I believe part of the definition of species is they can't mate with another. It just deals with genes pretty much...


As for ur other question, evolution

when a male donkey and female horse make a baby its called a mule.

donkeys and horses have a different number of chromosomes so their offspring are usually sterile.

if 2 similar animals have these problems imagine the problems your manigator will have.

plants are known to hybridize a good bit but thats a much different area.

there are some animals that have have hybridized tho this is rare and an area that we dont really have a lot of knowledge on. i remember reading something about hybrid sharks.

Different number of chromosomes.

Granted there can be hybrid animals, but they immediately hit hybrid infertility.

Plants, however, can mate with themselves and become polyploids.

so centaurs arent real?

IVE BEEN LIED TO?!?!?!

the reason that, no viable offspring is born, can be either pre-zygotic or post-zygotic, in this case lets say the two species successfully mate and the sperm is in the female reproductive organ, then

prezygotic:
1. the sperm died due to not being able to adapt to the vagina of other species, or is killed by the immune system of the female
2. the sperm enzyme in the acrosome cannot digest the jelly coat of the egg of other species
3. the sperm nucleus does not fuse with the female nucleus

post zygotic, in this case, the male nucleus gets into the female egg, but:
1. the zygote does not develop because the chromosomes does not match, i.e. the information on the genetic material does not match between the two individuals
2. the fusion of nucleus is successful but the embryo died, because genetic information is not matching
3. the hybrid get birth but is not able to survive
4. the hybrid can survive but is not fertile

if this blow your mind, remember that one more chromosome #23 in human already causes down syndrome, let alone so many difference between chromosomes in different species

btw, scientific research need to pass some ethical approval before proceed, i dont think any committee would pass this, i personally think your idea is gross

Hmm well I think it would be a good study.
If the scientific community wont do it then I will pay some researchers in russia or somewhere to conduct the experiment
on human women to
taking the sperms of an alligator and dolphin to be put into a womans vagina

This dude really wants furries to be real =/
