Hey all you pedes and frens, have you ever argued abortion with a lefty?

If you have, you know they are all about "science" and shitting on religion.

Trying to argue about God and the soul just falls on deaf (or dumb) ears.

But, in my experience, some are willing to listen to scientific arguments.

So, I've come up with a completely novel, purely scientific argument for this situation. It even uses evolution, for an added argumentative bonus.

I think this argument is purely my own invention. I've never heard anyone use this argument or anything even close to it, but I have used it personally on my smartest atheist friend and he was dumbfounded. In fact, he still is, regarding this.

Feel free to use it ad nauseum without attribution. Here goes, sorry for the length:

Once you've broached the subject and think the time is right, ask your lefty friend if they are open to a purely scientific argument that may be at odds with what they currently think. "What if I could prove it to you scientifically?" is a good question.

Assuming they say yes, ask if they are familiar with tetrapods. It doesn't really matter if they are or not. Just hit them with a sciency word like tetrapods in a question first and they'll listen harder.

Then hit them with this:

Tetrapods are the animals from which all mammals, reptiles, birds, and amphibians evolved hundreds of millions of years ago. You know evolution, right? We are mammals, and you know animals like frogs, toads, and salamanders are amphibians.

The word amphibian breaks down into "amphi" meaning both and "bian" which is a form of bio meaning life. We use that word because amphibian females lay their fertilized eggs in bodies of water like ponds. The eggs hatch and become tadpoles, which then live in the water while they continue to develop.

You've seen tadpoles, right? Yeah, everyone knows tadpoles. Anyway, tadpoles eventually fully develop into frogs or toads or salamanders. They grow legs and develop lungs and crawl out of the ponds to live the rest of their lives as adults of their species.

So, we use amphi for both and bian for living thing, because they live both in water and on land. All pretty straight forward, very basic science, isn't it? Grade school stuff.

Now, let's go back to the tetrapods. Mammals and amphibians both evolved from tetrapods, but obviously we evolved differently. Whereas amphibians developed to reproduce by using ponds, mammals evolved to retain the fertilized eggs within the mother herself.

So, instead of releasing fertilized eggs into ponds, mammals keep their fertilized eggs within the womb of the mother until they can survive on land. As every mother of a premature baby knows, one of the very last things to develop in utero are the lungs.

Notice how this is the same as the mature tadpole, crawling out of the pond. The last thing to develop are the lungs, suitable for breathing air. You see, we evolved from the same creatures, but simply in different ways.

Now, just imagine if you were a froggy parent, jumping around the pond. Seriously, imagine that you are an amphibian instead of a mammal, still conscious and able to think and all that, just biologically different in the way you reproduce.

Would you really advocate that killing your own little developing tadpoles while they are swimming around in the pond before they can grow legs and lungs is morally okay?

For mammals to advocate for abortion is just like amphibians advocating for the death of their own baby tadpoles, swimming in front of them. It's like claiming that it's okay for bird parents to toss their own developing chicks still in their eggs out of the nest to smash on the ground below.

It makes no sense ethically if we take the biology and evolutionary science seriously.

Do you see? According to basic evolutionary biology we know we evolved a "pond" inside the mother. It's called a womb. It's supposed to be a safe place, like the frog pond. Amphibians are called amphibians because it's obvious they have two life stages and live in two different environments. We do, too. It's just not as obvious.

Our first life stage lasts about nine months, inside the "ponds" in our mothers. The second stage is the longer stage, outside the womb, breathing air on dry land. It can last for many years. But, through it all, we are still the same person.

If it's wrong to kill a human after birth, then it's wrong to kill a human before birth.
