Practical applications of the multi-species coalescent model are, however, limited by the need to integrate or sample over all gene trees possible for each genetic marker. Here we describe a polynomial-time algorithm that computes the likelihood of a species tree directly from the markers under a finite-sites model of mutation, effectively integrating over all possible gene trees. The method applies to independent (unlinked) biallelic markers such a","authors_text":"Arindam RoyChoudhury, David Bryant, Joseph Felsenstein, Noah Rosenberg, Remco Bouckaert","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"q-bio.PE","submitted_at":"2009-10-21T22:34:45Z","title":"Inferring Species Trees Directly from Biallelic Genetic Markers: Bypassing Gene Trees in a Full Coalescent Analysis"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0910.4193","kind":"arxiv","version":2},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:a8f5ef5659682766f4d5b8086d69d213c784572596a98f08261a696c5dd4542e","target":"record","created_at":"2026-05-18T04:09:03Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"f88989022115157d28a664b79959d3f6090ff0059048803e7fa40f2a67788e5b","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"q-bio.PE","submitted_at":"2009-10-21T22:34:45Z","title_canon_sha256":"f4eeb35f6fa2a5c65bf61b6accb447fc28aebb7986897196b7f8f70f0e2b5717"},"schema_version":"1.0","source":{"id":"0910.4193","kind":"arxiv","version":2}},"canonical_sha256":"f8132eccb54dabf9b28c6bf1c54890c9f7c88a345c0810a68077d729859d8406","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"f8132eccb54dabf9b28c6bf1c54890c9f7c88a345c0810a68077d729859d8406","first_computed_at":"2026-05-18T04:09:03.953489Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:09:03.953489Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"X6eRXvMn2pR+K+M+dhuw1qrPPvmKTPv2Dav85TvSe76NsIbWg6AyNr4Rta9Uh+c2aepHr8otAJDmtNDrwao8Dw==","signature_status":"signed_v1","signed_at":"2026-05-18T04:09:03.954015Z","signed_message":"canonical_sha256_bytes"},"source_id":"0910.4193","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a8f5ef5659682766f4d5b8086d69d213c784572596a98f08261a696c5dd4542e","sha256:0659701f1f8cb9e4022f36d0aca10e3424c8248421242bb9db2fc5d1671a3a02"],"state_sha256":"3702ded067c2799087fdfc60ebe01e321f2066e69b692432e68344bcdc25b117"}
