Of course mitochondrial DNA is passed down from one generation to the next! How otherwise would you expect mitochondria to continue to exist in the next generation of plants or animals? The main difference is that mitochondria pass down the mammalian generations by hitching a lift inside the mammalian mothers egg. Humans. other animals, plants and many singular celled organisms are hosts to vast cities of these tiny critters. We live in a symbiotic relationship with them. They are dependent upon the plants and animals as hosts and we are dependent upon them for metabolising sugars and providing energy for us. Mitochondria are extremely old creatures, their origin going way back in time and they are amongst the earliest organisms to have evolved on the planet. We have studied their DNA and have followed their ancestry back tens of thousands of years in the humans who left Africa.
This strengthens the inductive argument, however, I am still open minded, life is more fun that way.

Your link to the arstechnica article, while interesting, is talking about how inaccurate cheap tests may be that are offered to people for tracing their ethnic origins using only a handful of genes as markers. The article is not related to the detailed study of DNA across all genes regarding the comparison of human DNA to that of other apes and other animals.
OK.

The family tree exists. You can deny it all you want and for some weird reason claim that each part of the tree isn't linked, but that would be silly. The image presented by DNA and fossil evidence is very much that of a tree, with new animals and plants evolving from older species over vast periods of time.
I don't deny it. I am sure DNA similarity exists, and scientists have made classifications based on DNA similarity.

If this is what you are suggesting it is beyond ridiculous.
There are a lot of possibilities. Aliens may have dropped off different species over time - which we see in the fossil record. These species have common DNA because it was the same alien GOD who did the genetic engineering.
It may seem ridiculous, however, it is possible, and the blockbuster movie Prometheus 2 will have the world wondering if it could be true. What if the fossil record is the order of the different species GOD put on the Earth ?

As we know the mechanisms by which evolution works at both the causal level and the biochemical levels then postulating an external entity (be it aliens or gods) as the cause is unnecessary and there is no evidence to support it anyway. If I throw an apple at you and it hits your head, you could also speculate that an alien plucked the apple out of my hand using their (Star Trek) transporter technology then made it appear again at the side of your head with an added horizontal velocity. I of course deny all responsibility... it woz the aliens wot dun it... honest...

It is a case of connect the dots, with millions of dots there to draw the picture and conclusions from. I'd definitely call it proof. It is either proof or an incredibly massive coincidence of unbelievable proportions. That is before even factoring in mitochondrial DNA which passes down the maternal line.
It would be an inductive argument.
I am not a biologist, however, it does not seem like they can show that similarity means ancestry. Especially when I read this ...
"In human mitochondrial genetics, there is debate over whether or not paternal mtDNA transmission is possible. Many studies hold that paternal mtDNA is never transmitted to offspring".
http://en.wikipedia.org/wiki/Paternal_m ... ansmission
Without parent mitochondrial DNA being passed down, then "DNA evolution evidence" is lost, right ? All you would have left is "connecting the dots" with similarities, and assuming similarity means ancestry. A possibly very good inductive argument at best.
This is only mitochondrial DNA, not our regular human DNA. We get our mitochondria from our mothers, so they can be used to establish whether someone is a female ancestor through the female line. For male ancestors they use the Y-chromosome.
So parental DNA is passed down, it's just that our mitochondria are transmitted through females.
edit: I just saw Tallyman gave a much more comprehensive answer and I'm just being redundant

Nice.
Really though, seriously. We have people right now that are doing some pritty crazy experiments with DNA. Laws are the only things to keep them from doing more. We have horses that people evolved. They were smaller than a goat. Turned dogs into nothing more than a crap toy that can't live in the wild for more than a week without getting killed by a bald eagle. Cats too. All of which domesticated, and evolved from humans. Neanderthals gone. Evolved. Interbred into a different species. New stuff going on here and there. Small amounts, but noticable. The ways and the means are probably wrong, but it exists none the less.
I dunno why I waste time on this. Soo unimportant to tell. Look at your family tree, that should give it away right there. Your momma was a -------------.
wut?
