Okay after reading the 20 or so absolutely stupid posts I guess I might actually throw something "sciencey" in here.

Abnormal "facies" are very common in genetic mutations. Often times you can diagnosis a genetic disorder by just facial features. Edward's Syndrome (trisomy 18) and Down's are great examples. There are also Harliquinn facies. Pauau (trisomy 13) facies. A bunch of them.

During development the mutations will cause the face, an extremely complex part of our body to go completely out of control. There are dozens of muscles and more than a dozen bones that all need to precisely come together and form the features we associate with looking "human". Errors can be horrific. (like I mentioned, check out harlequinn facies for a real nasty one.)

Now I don't claim to be a zoologist. But I am going to go on stretch here and say that probably the lamb had a developmental or genetic mutation or disease that caused it for fail to properly form a snout and normal face we see in a lamb. It just so happened the horrific teratoform it took looked like the alien human face in the abyss.
 
Well we are finding newer species from different animals breeding in the wild.........So could human sperm ever fertilize an egg of another species?


Reminds me of a B-movie I read about..........Revenge Of Billy The Kid....Never seen it....

To be honest, there's very little that stops any sperm from "fertilizing" any egg. However due to chromosomal incompatibilities, most resulting embryos will quickly become non-viable, and ultimately be destroyed in-utero.

Think about it, humans have 46 chromosomes and millions upon millions of genes that match up across the chromosomes. Sheep have 54 chromosomes. Potentially there is some genetic information in any of the 8 haploid chromosomes that require the other half of the gene in order to express a viability trait (say, for example, a functional piece of a major organ). Without that matching chromosome, that piece may never be able to form correctly, thus producing a non-viable offspring.

On the other hand, there could be cases, simply by random probability due to the sheer number of genes, possible mutations, and other factors, that all of the appropriate genes required for viability and development are properly available in the diploid chromosomes, or that a diploid match isn't required within the non-matched haploid chromosomes. In this case, it may be possible for a viable offspring to arise. This is much more likely to happen in closely related species - a common example is horses. Wild horse species have 66 chromosomes, while the domesticated species have only 64, yet they are often capable of interbreeding and producing viable offspring.

Mutations and evolution are a wonderful thing. They can also pose some downright frightening situations as well.
