Normal humans have 23 pairs of chromosomes (46 total - an inarguable fact). Chimps have 24 pairs of chromosomes (48 total - another fact). This makes chimps between 95% and 98.5% genetically similar to humans (depending on which studies you read e.g "http://www.answersingenesis.org/tj/v17/ i1/DNA.asp"). Chimps are NOT defined as being human - they are a separate species. Humans cannot mate successfully with chimps due to the differences in chromosomes.

There are many genetic mutations that can result in a 'human' ending up with either more or less than 23 chromosomes - one of which is trisomy of chromosome 21 (in 3 different variations) which results in Downs Syndrome (47 chromosomes). This makes Downs Syndromes 97.87% genetically similar to 'normal' 23 chromosomed humans. Downs Syndromes and humans cannot mate successfully due to the differences in chromosomes. Therefore, they are not human.

I can't believe you would make a comparison between chimps and people with downs syndrome.

Downs syndrome is a defect that occurs when TWO HUMANS mate. Chimps occur when two chimps mate.

To suggest that the product of two humans would be something less than human simply because of a genetic abnormality is maddening.

Maybe instead of hanging out on CreateDebate making stupid arguments, you should get out there and volunteer with an adult group home to meet some people with downs syndrome. Don't be afraid of what's different.

You're ridiculous.

Humans with genetic abnormalities are still human. If a chimp were to get an extra pair of chromosomes, would that make them human? No, it would be a chimp with a genetic disorder. Some species of deer or rat have 46 chromosomes; you don't argue that they're human, it's the content of the chromosomes, and not the number, that mattes.

Two organisms of the same species cannot create an organism of a different species. Downs Syndrome is merely a mutation that occurs from one of the parents during meiosis. Just because they cannot reproduce successfully doesn't mean they're not human. Can we say the same about infertile people?

Why don't you ask the parents of a Down's Syndrome child if they think their child is human or more similar to a chimp! What a comparison!!!

How about some evidence for people with down syndrome not being able to mate with other humans due to the chromosomal difference? And I mean complete with reputable sources.

Using relativity proven too 99.3% as of a few years ago from 2009 in a milky way galaxy....they are closer related too humans then monkeys....african americans are geneticly further realted from other in there family...IE:Brother-Brother

Sister-Sister Brother-Sister....alot like wolves can mate Mother-Son and still survive genitcly without major defects....(witch arent human but if a wolf chould speek japanese it chould declare itself a "sapien" becouse indeed it is "being")...To every single white person on this planet from each other...so tecnicly...somebodys an ET and somebodys an Alien...A foot race with a wolf is a bad idea...Its almost as if they decide in conception not to fucking bother with your Fail...I mean the missing link vs god is a hard topic to topple...but I think i jsut about covered it.

its disgusting anyone would consider others with disbilities to be sub-human! This makes me feel sick, its the very people who think that they are not humans, that are inhuman themselves!

thats not fair to say that a downs syndromes are not human and anyone that says there not are idiots
