Background: Previous phylogenet.c st.dies t.at.include t.e four recognized species of Gallus have result.d in a number of dist.nct.t.pologies, wit. lit.le agreement. Several fact.rs could lead t. t.e failure t. converge on a consist.nt.t.pology, including int.ogression, incomplet. lineage sort.ng, different.dat. t.pes, or insufficient.***: We generat.d t.ree novel whole genome assemblies for Gallus species, which we combined wit. dat. from t.e published genomes of Gallus gallus and Bambusicola t.oracicus(a member of t.e sist.r genus t. Gallus). t. det.rmine why previous st.dies have failed t. converge on a single t.pology, we ext.act.d large numbers of ort.ologous exons, int.ons, ult.a-conserved element., and conserved non-exonic element. from t.e genome assemblies. t.is provided more t.an 32 million base pairs of dat. t.at.we used for concat.nat.d maximum likelihood and mult.species coalescent.analyses of ***: All of our analyses, regardless of dat. t.pe, yielded a single, well-support.d t.pology. We found some evidence for ancient.int.ogression involving specific Gallus lineages as well as modest.dat. t.pe effect. t.at.had an impact.on support.and branch lengt. est.mat.s in specific analyses. However, t.e est.mat.d gene t.ee spect.a for all dat. t.pes had a relat.vely good fit.t. t.eir expect.t.on given t.e mult.species ***: Overall, our dat. suggest.t.at.conflict. among previous st.dies probably reflect.t.e use of smaller dat.set.(bot. in t.rms of number of sit.s and of loci) in t.ose analyses. Our result. demonst.at. t.e import.nce of sampling large numbers of loci, each of which has a sufficient.number of sit.s t. provide robust.est.mat.s of gene t.ees. Low-coverage whole genome sequencing, as we did here, represent. a cost.effect.ve means t. generat. t.e very large dat. set. t.at.include mult.ple dat. t.pes t.at.enabled us t. obt.in a robust.est.mat. of Gallus phylogeny.
