Do you think it is possible for an animal (not human) to impregnate a human?

Answer 1

No it's not.

Answer 2

No. This is not possible. Interspecies sexual union is not possible because of the different characteristics of the sperm and egg cells. Human sperm cells are perfectly evolved to combining with human egg cells. Also, (and this is true even in humans), a female will recognize sperm as a foreign invader and mount and immune response, human sperm cells have evolved methods to survive this but another species' sperm may not. Even if another species' sperm cell was able to enter the egg, the number of chromosomes would not match up, internal chemistry and differences in cell signalling wouldn't be the same and the zygote would abort itself.

In some instances this is possible though. Animals within the same class but different species can sometimes mate, but produce offspring that are sterile.

eg:
donkey + zebra = zedonkey
whale + dolphin = wholphin
dog + wolf = dolf
horse + donkey = mule

there are many others...

Answer 3

No, it is not possible, and here's one reason why:

Humans have 23 pairs of chromosomes. Most other animals have different numbers (cats, for example, have 54). Chromosomes are long strands of DNA.

In order to create a healthy embryo, half of the chromosomes have to come from one parent, and half from another.

Also, genes that do certain things are in different places in the human DNA than they are in other animals. So if you tried to add some chromosomes and take away others, you have no idea whether you would actually get the right genes in place.

There are lots of other reasons why the answer is "not a chance."

Answer 4

Not yet (read on):
The mixing of humans and animals in the name of medicine has been going on for decades. People are walking around with pig valves in their hearts and scientists have routinely injected human cells into lab mice to mimic diseases.
But the research is becoming increasingly exotic as scientists work with the brains of mice, monkeys and other mammals and begin fiddling with the hot-button issue of cloning. Harvard University researchers are attempting to clone human embryonic cells in rabbit eggs.

During his State of the Union speech in January, President George W. Bush called for a ban on "human cloning in all its forms" and "human-animal hybrids," labeling it one of the "most egregious abuses of medical research."

Stanford University bioethicist Christopher Scott said "the stuff that raises the most ethical concerns" are the experiments that implant human cells into animals' brains. So far, Scott and others know of no researcher that has come close to putting enough human cells into animal brains to confer any signs of humanity, such as emotion.

The report endorsed research that co-mingles human and animal tissue as vital to ensuring that experimental drugs and new tissue replacement therapies are safe for people. But the report warned that the "idea that human neuronal cells might participate in 'higher order' brain functions in a nonhuman animal, however unlikely that may be, raises concerns that need to be considered."


Apparently, these people believe that somehow the type of nerve cells present in a brain determine its function. A cursory review of any neuroscience text would show that it's that the networks of connections formed by neurons that determine nervous function.

It's unfortunate to see legitimate research hindered by unfounded fears of a real-life Island of Dr Moreau.

Answer 5

If by human you mean Homo Sapiens, and by non-human you mean non-homo sapiens, then yes it is possible.

That is because non-humans can be classified as Neanderthals, one of the earliest forms of 'human beings', except they are not homo sapiens, the modern man.

Neanderthals can most definitely mate with homo-sapiens and give birth to mixed babies. I know it is disgusting but true, because their DNA is no different structure from ours.

Answer 6

A long time ago i heard about a pig that had piglets with human ears,sounds like farmer joe was makin bacon!

Answer 7

My fiancee was telling me something the other day about monkeys being able to breed with humans, but their offspring would be sterile, much in the same way lions and tigers can breed to create ligers, but ligers are sterile. Interesting question!

Answer 8

if it is possible then it would not be in the normal way.. scientist would be playing with DNA and switching things around just so it would all fit together... lets hope they dont try it in the future

Answer 9

I'm not sure,


But you put me off my dinner thinking about it!

Cheers!

Answer 10

its not possible. but there are a lot of movies about it.

Answer 11

What are you doing, that you need to ask this?
