There is no scientifically plausible basis for a ban on abortion - it's entirely rooted in Christian fundamentalism, and those people do not believe in a middle ground.

A secular, liberal-democratic society is based on property rights and bodily autonomy. In such a society, banning abortion makes no sense.
Science has nothing to do with it.
Is there a scientifically plausible basis for a ban on other forms of homicide, or on genocide?
Science just tells us that a 24-year-old Korean, a 6-year-old English child, an American five minutes before birth and a Frenchman 5 weeks before birth are all equally human beings and all equally different from any other human beings. It doesn’t have anything to say about the morality of killing any of them, or in what circumstances.
If your moral position is ‘no homicide except in self defense,’ then that plus the scientific facts points in one direction. If your moral position is ‘homicide of slaves, children, fœtuses and other humans owned by another is permissible when the owner desires,’ then that plus the scientific facts points in another direction. If your moral position is ‘homicide of those without a functioning brain is permissible,’ then that plus the scientific facts points in yet another direction.
Scientific facts on their own are just facts; they just talk about what is, not about what one should do or not do.
Of course, you still need a non-scientific, moral basis to decide whether murder is bad, and other circumstances pertaining to abortion (in general and each case specifically).
"kill" = "cause to cease living", "living" is pretty well defined (it's not entirely obvious for edge cases, like viruses, but quite obvious for cells)
"human" = pretty obvious as well, simply look at genetics. I mean, obviously an offspring of two humans is a human (for the next 100k+ years)
Except killing another human is allowed in other circumstances, especially in Texas. Using "science" to make a special case for a fetus seems like a pretext when that science no longer applies outside the womb.
