According to their website:
“The goal of the OpenWings Project (http://blog.openwings.org) is to understand the evolutionary history of and evolutionary relationships among birds.”
“One of our goals in this project is to collect genomic data from DNA samples that have an associated voucher specimen in a research collection.”
“The fundamental and missing piece of this otherwise powerful comparative biology toolkit is an accurate and complete avian phylogeny. The overarching goal of the OpenWings Project is to fill this gap by producing: a complete phylogeny for all 10,560 bird species that will provide a unifying framework for understanding the origins and maintenance of avian diversity… as well as serving as a case study of the benefits and challenges of sampling all species in a major clade.”
Start with a dozen diverse birds. IF the genotypes and phenotypes produce identical tree topologies, double that number and test two dozen birds. IF those produce identical tree topologies, test four dozen birds. Etc. Etc. You’ll get to 10,560 at that rate in ten steps with confidence that your results have been validated at every step.
If at any point the genotypes and phenotypes don’t produce identical tree topologies, review your paradigms and hypothesis. There is something wrong if they don’t match. In my testing, birds genes do not recover the same tree topologies as bird traits. Don’t waste your time and money testing 10,560 bird genes only to find they don’t deliver the same tree topology as bird traits.
Since no large scale genomic and phenomic studies of birds have ever matched, just study phenotypes. Then you can include fossils and you won’t have to exclude taxa critical to understanding the phylogeny of birds. Click here for a starter list of taxa.
I would have contacted the OpenWings Project directly,
but (at present) they don’t provide access except through apps (like Twitter) I don’t have or want.
We looked at another DNA analysis of birds
by Prum et al. 2015 here and here and found it matched dissimilar taxa while separating similar taxa. So beware of DNA. It can only be validated with trait analysis and too often it produces odd results needing odd explanations.
