Matthew 1:6-16 traces Jesus's lineage through David's son Solomon. Luke 3:23-31 traces it through David's son Nathan. Both genealogies claim to give Joseph's ancestry, but they pass through two different sons of David and produce two almost entirely different lists of names between David and Joseph.
Proposed answers
People have answered this in several ways; GEBible presents them as equal peers.

Abijah became the father of Asa.8Asa became the father of Jehoshaphat. Jehoshaphat became the father of Joram. Joram became the father of Uzziah.9Uzziah became the father of Jotham. Jotham became the father of Ahaz. Ahaz became the father of Hezekiah.10Hezekiah became the father of Manasseh. Manasseh became the father of Amon. Amon became the father of Josiah.11Josiah became the father of Jechoniah and his brothers, at the time of the exile to Babylon.12After the exile to Babylon, Jechoniah became the father of Shealtiel. Shealtiel became the father of Zerubbabel.13Zerubbabel became the father of Abiud. Abiud became the father of Eliakim. Eliakim became the father of Azor.14Azor became the father of Zadok. Zadok became the father of Achim. Achim became the father of Eliud.15Eliud became the father of Eleazar. Eleazar became the father of Matthan. Matthan became the father of Jacob.16Jacob became the father of Joseph, the husband of Mary, from whom was born Jesus, who is called Christ.

This is the genealogy problem that has occupied harmonizers since the third century. Matthew 1:6-16 runs David → Solomon → Rehoboam and down the canonical royal line of Judah's kings to 'Jacob begat Joseph.' Luke 3:23-31 runs (in ascending order) Joseph → Heli → ... → Nathan → David. They agree on David at the top and Joseph at the bottom and diverge almost completely in between: different son of David (Solomon vs. Nathan), different intervening names, and even a different number of generations (Matthew schematizes into three sets of fourteen; Luke lists more links from David to Joseph). The lists touch only at two suggestive points — both pass through Shealtiel and Zerubbabel around the exile — and even there the surrounding names differ, which itself resists a simple two-fathers theory.
Two classical harmonizations dominate, and each should be stated at full strength. The first, the levirate theory, goes back to Julius Africanus (early third century), whose letter to Aristides is preserved by Eusebius (*Ecclesiastical History* 1.7) and was revived in the twentieth century by Machen. On this view one Gospel names Joseph's biological father and the other his legal father, the two lines having crossed through a levirate marriage (Deut 25:5-10): a man died childless, his half-brother (of the other Davidic line) married the widow, and the son was reckoned legally to the deceased but biologically to the living father. Africanus specifically located the crossing at Heli and Jacob (Matthew's Jacob and Luke's Heli being half-brothers by the same mother). The theory is internally coherent and not impossible, but it is unfalsifiable and rests on a tradition Africanus says came from Jesus's relatives (the *desposynoi*) for which there is no independent control; it requires the levirate union to fall at precisely the generation needed, and the two lines must then diverge all the way back to David rather than only at the last step, which a single levirate marriage does not explain.
The second, the Mary theory, was popularized by Annius of Viterbo and John Lightfoot and is standard in modern apologetics (Geisler and Howe): Matthew gives Joseph's line, Luke gives Mary's, so the two trace Jesus's descent through both legal-paternal and biological-maternal channels. Its fatal difficulty is the Greek of Luke 3:23: *ōn huios, hōs enomizeto, Iōsēph tou Hēli* — 'being the son, as was supposed, of Joseph, the son of Heli.' Luke names Joseph, not Mary, and Heli as Joseph's father. To salvage the theory one must read 'of Heli' as 'son-in-law of Heli,' a sense the bare genitive does not bear and which no ancient reader would supply, especially as every other link in Luke's chain is a literal father-son genitive. Marshall and Fitzmyer both note that the *hōs enomizeto* ('as was supposed') already does the work the harmonizers want — it flags the *legal* and *putative* nature of Joseph's fatherhood given the virginal conception — without any appeal to Mary.
The critical consensus (Brown, *Birth of the Messiah*; Fitzmyer, AB Luke; Bauckham, *Jude and the Relatives of Jesus*) is that the two genealogies are independent constructions, each assembled to establish Davidic descent but drawing on different traditions and serving different theological ends. Matthew's Solomonic royal line presents Jesus as the legitimate heir to the throne of Judah, structured into his stylized 3×14 (the *gematria* of David, dwd = 14). Luke's line through Nathan — David's son but not a king — may deliberately route the messiah around the discredited royal house (Jeremiah's 'curse' on Jeconiah, Jer 22:30, falls on Matthew's line) and toward a non-royal Davidic descent; some have linked it to the prominence of 'the house of Nathan' in the messianic mourning of Zechariah 12:12. Bauckham further argues both lists incorporate genuine pre-Gospel family tradition, which would explain the Shealtiel-Zerubbabel overlap without making either list a complete biological record.
The decisive point is logical: two lineages passing through two different sons of David cannot both be Joseph's biological ancestry, and the harmonizations each pay a price — the levirate theory invents an unattested marriage at a convenient point and still cannot explain divergence all the way back to David, while the Mary theory must override the plain Greek of Luke 3:23.
Where the critical reading lands: genuine genealogical discrepancy; the two principal harmonizations require either an unattested levirate marriage or a forced reading of Luke's Greek.
