Forget the "findings" section. Look at the text of 18 USC 1841, every word of which is operative. 
It refers to a being in utero as a "child," and also as an "unborn child." The statute also states that the term “unborn child” means a child in utero, and the term “child in utero” or “child, who is in utero” means a member of the species homo sapiens, at any stage of development, who is carried in the womb.   

Roe v. Wade was premised on the notion that under the common law. there was no firm consensus that a being in utero was regarded law as a person. The post Roe statute expresses the will of the people---that's what statutes do in a democracy: express the will of the people---that a being in utero be regarded as a person.  If you don't think this undermines Roe, your head is in the sand.  That it does so is indeed proved by the vehemence with which the opponents of section 1841 have attacked it, and their stated reasons for doing so.  "C'mon, Baggy, get with the beat."
