PubMed

PubMed is the online database of the National Library of Medicine.  You can find it at:

http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=PubMed

Whenever anyone makes a claim about evolution (or even physics and chemistry) this should be your first stop to check it out. 
Evolution collapsing? Enter the term "evolution" and see the number of papers you get.

Beneficial mutations or gain of function mutations?  You can search both of these.

You will want to use the Boolean operators AND and NOT in order to keep from being overwhelmed with the number of articles.  Also, the "related articles" tab is extremely useful.  Find an article that is what you are looking for and hit this link. It often picks up  articles not in your original search. 

All the recent articles come with abstracts and some of them link you to free complete copies of the paper.  However, most journals will ask a fee to download a copy of the paper. 

Science is open to everybody. Take advantage of that.  Have fun!

DNAunion: PubMed is the standard.

Another good internet science source is WWW.BMN.COM (formerly www.BioMedNet.Com). They also have a search engine with a huge database of articles, it's free (or at least it was when I signed up a few years ago), and you can order full-text articles of interest pretty cheap.

Of course there is always PNAS (proceedings of the national academy of sciences). It's governement supported so all articles are available free online starting a month or so after publication. It's not at the same level as Science or Nature, but it is a top journal. www.pnas.org

Thanks for the links!

DNAunion: I just want to add one more: www.sciencemag.org. This is the site associated with the journal Science (the AAAS's weekly journal).

Here's the "cool" part for nonmembers. Anyone can purchase full access to an article (for a given amount of time) for a poultry fee.

I think that was aimed at chickenman

Talking about PubMed, I used to run a medical search engine based on Google here:

www.medlinepro.com

It still works, but it's now hosted on a free host, and I haven't updated it for almost 2 years. No time to do anything with it, since I am busy with this site.

PubMed will automatically post links to PNAS, Science, Nature, and the other online journals. Which is why I didn't list them. I figured you'd get to them through PubMed.

BTW, there is no way to "judge" between journals. I don't think any of the articles for which Nobel Prizes were awarded were published in Science. I happen to use Science and Nature when possible simply because every public library has a subscription, so it's easier for people to find. PNAS has had the problem for years that NAS members got 2 articles per year that avoided peer review. Now there are 2 tracks to PNAS -- the traditional submission by an NAS member and the more standard peer-review track.
