Science journalist are worse than gaming journos.
Ain't that the truth!

Ugh. We didn't smang them did we?
The actual purpose of the comparison in this particular case is precisely to show that science is not a faith. In this case, what we're seeing is new evidence arriving, and then seeing scientific beliefs changing based on that new evidence. We used to think modern humans were much younger on an evolutionary time scale; evidence comes in suggesting humans are older; science adjusts accordingly.
This is explicit, complete and absolute contrast to the concept of faith, which is by definition something you believe in regardless of the evidence. If you have faith in X, then no amount of new information will adjust or revise your view of X.
That's why this particular sort of correction is so important. While I will again emphasize that religion and science are often compatible, this particular situation highlights the most important difference between the two systems; science adjusts to new facts and new evidence, while faith does not.
Science is the problem with scienceOne of the biggest problems with science is that what was once regarded as absolute truth is no longer true because of new data or testing methods. Evolution has never been proven and there always seems to be new data that just creates more questions than answers.

So, basically, we're starting to realize that there might be entire populations of hominids that lived that we don't even know about.
I'm becoming depressed but also ecstatic
This is not open to discussion. This is literally the definition of faith; a belief in something regardless of evidence or proof. Both of the definitions you just applied fit that description. Faith is by literal definition the belief in something regardless of evidence.
Yes, it is. Faith does not preclude re-interpretation.
As time goes on, we get much better at reconstructing sequences from more and more deteriorated samples. You probably don't need very many intact markers to make the link to any particular genetic tree.
In this case the half life refers to the degradation of the DNA's "backbone", which consists of sugar and phosphate molecules; organic matter, obviously, tends to break down quickly, but there are a few instances where remnants of soft tissue are preserved remarkably well intact. I was just reading about this in The Economist. Apparently a new paper was just released trying to explain this phenomenon:It's important to make the distinction between physical half life such as that of radioactive isotopes which follows an exponential decay very closely, and biological half life, which is simply defined as the time until roughly half the molecules will lose their original properties. The latter is a more complex pattern of deterioration and is greatly affected by external conditions, including the initial number of molecules! (In exponential decay the deterioration pattern is independent of sample size). In the case of organic macromolecules like DNA, not just temperature, but also moisture has an extremely significant effect on how long a sample will be preserved, which makes sense.
I managed to learn all this during my investigation, so no harm done
edit: More about deterioration and sample contamination can be found here:

In this case, 700,000 year old prehistoric horse DNA was successfully reconstructed even though roughly 99.7% of the sample had been contaminated by microbial DNA throughout the millenia.

science says we did! Melanesians have high relative incidence of Denisovian traits in their genotype.
You cannot maintain faith in an idea and also modify or drop it.
You can and do modify your beliefs all of the time. Your beliefs are not the exact same as they were 10 or even 5 years ago. Faith that does not change and grow is simply dogma.
science says we did! Melanesians have high relative incidence of Denisovian traits in their genotype.
But in order to modify those beliefs you need to stop having faith in them being true to do so. If I have faith that god does not want gay people to marry the same sex and I change my mind, I necessarily have lost faith that god does not want gay people to marry the same sex. There's no way around that. I might replace that with having faith that god doesn't mind if gay people marry the same sex but I had to lose faith in another belief.

Not necessarily. Beliefs can be maintained, but modified. If I believe God is responsible for the universe and, after studying the original language, I discover that the word we read as day means a specified duration of time and not 24 hours, then I have grown in my understanding of what is meant and adjust for other possibilities. I still believe that on the 7th "Day" God rested, but I can better understand it to mean we are STILL in the 7th "Day." It has been modified, not destroyed.

-- It's the entire basis of population genetics, landscape genetics, and modern conservation biology in fact. Using microsatellite mutations we can even directly measure genetic differentiation across populations over very short time periods.Evolution is defined as a change in allele frequencies in a population over time. There IS proof of that occurring in nature. Speciation has also been observed in nature within our lifetime.
My question is: How do we know that our fossil record and DNA dating methods are precise and accurate?
New evidence arrives, scientists adjust their understanding of history. Even in pretty significant ways, as in this case.
It would be so much cheaper if scientific textbooks required no revision and no editing. If only they could avoid costly revision and editing like many religious texts do, I'm sure my Biochem textbook from Sophomore year would have been noticeably cheaper.
[Augustine quote]
Yearly textbook revisions at undergrad or below are entirely a money-making scheme by publishers to subvert the used market by fucking with the page order (justified by a few well=placed spelling errors) just enough to make last year's syllabus off point. I've never seen any textbook revisions add any significant new information or clarification ever. If it's not a scam then it's willful ignorance at such a staggering level as to question the academic credentials of those writing them. /rant
Wow. We really know nothing about anything, do we?
