All of the links, below, are active. For the most part, I'll leave it up to you to click on whatever links you find interesting. However, if I want to highlight a particular topic, I'll give a direct link for it below the list of key components.
Since almost all of this is new to me, I've been clicking on a link that catches my attention and then allowing myself to click on sublinks within the main article. But I don't stop there. If a subsublink catches my attention, I click on that, etc., until I've followed a meandering path through the information, most likely without reading any of the links completely.
I expect that I'll be repeating this open-ended exploration frequently.
I noticed that the list of key components, above, didn't list "gene", so I've provided a direct link to the section of the article on DNA which specifically discusses genes.
Gene duplications and the origins of vertebrate development. - PubMed
"Gene duplication, followed by functional divergence of new genes, may be one class of mutation that permits major evolutionary change. "
" From amphioxus and vertebrate homeobox gene expression patterns, we suggest that there are multiple routes by which new genes arising from gene duplication acquire new functions and permit the evolution of developmental innovations."
