Alright I told a couple of friends I would make this for them so here it goes.

Furry's cannot exist in any shape or form of them being animal human beings. Furrys in the science world are known as Chimeras. So if you see Chimera it's me being sciencey and it helps me stay on track. I talked to my teacher about this and out of the conversation we have agreed that they can not exist within the boundaries of the science world... YET! I have come up with a couple ways they can exist while thinking about how they could and talking to my teacher. But before I tell you how, I must tell you why in the accordance of science that they can't exist according to science and such.

How they can't exist right now:

The form of any being on the planet being an animal or a human is created through Genetic coding. The genetics tell your body what your going to be. There is no way to re-write or insert genetic coding of a different set. This goes in the same as why if you weird beastiality people can not impregnate an animal and why different animals cannot make a hybrid. (I.E. Cat and a dog cannot make a CatDog) But there are exceptions like a donkey and a horse and makes a Mule. If you do mess with the genetics its hard to keep them together as you work. They are extremly sensitive and the slightest off of doing somthing could kill and destroy the gene before the transaction can be made to change it. This means if you wanted animal parts, a chimera, it would mean changing your genetic code making it into an animal/human gene. But there is a problem with that. The problem is since the animal code is not a familiar code to the body your anti-bodies will destroy and eradicate the code making the human gene left.
So in the thought Furrys can not exist with in the code of life and science.

And Now! the reason you are reading this in the first place!

How they can exist:

Furrys can be possible out of a couple of ideas and how. Chimeras can exist in fact one was made but Chimera also means a fusion of two creatures. They did make a chimera but it was in egg form. here is a link to it http://news.nationalgeographic.com/news/2005/01/0125_050125_chimeras.html. So it could happen in that way but not for a while. Another thought is using monkey genetics. By switching the monkey and leaving the human part and replacing the monkey one with a tiger or somthing. This is a way to do it since monkeys are close relatives to the animal world. (No I don't beleive in evelotution but monkeys are the closest to us) So using the monkey/human and using the human as a base could work but in the former part i say why the fusion cannot work. The monkey genes are not part of human unless born that way (thats why monkeys are monkeys) Its still abnormal to us so our body would kill it instantly. Yes we could put it in the baby in the womb but the baby already has genetics so it would block it or even kill the baby so most won't go for that. Another one is "Ghosting". Ghosting is hiding the genes to the host so the genes seem natural and the body takes it. We can kinda do this already but it's for a short peroid and it would kill as soon as it woke up since the genes wouldn't fuse yet. So if we could Ghost longer they could fuse and create new genes for the creature creating Chimeras. The Last one is using zombie bacteria. Hear me out on this and yes I said ZOMBIE. There has been recent research on ants lately finding a fungus on them turning them zombie for a bit. Here's a link http://news.nationalgeographic.com/news/2011/03/pictures/110303-zombie-ants-fungus-new-species-fungi-bugs-science-brazil/ The fungus controls the brain which controls the body. Using the fungi in someway (No I don't have full thought on this. It's just a thought) to control the body's anti-bodies to allow other genetics (animal) to be accepted to the body.


So there you go. Even in science there are loopholes! I hope you had as much fun as I did writing it. Thanks For Reading!!!!
