Apparently everything we know about primary sexual characteristics from our multiple evolutionary cousins simply doesn’t apply to homo sapiens. It sure is fortunate that we have social constructivist activists from the theoretical hypothetical Humanities to clear that up.
Wow that's a lot of sources, nice! Also I'm sorry but I didn't assume you were lookinh at my blog haha, anyway like I said I'm not a scientist but I did follow you hoping to learn more so maybe you're doing me a favor, and yes I think I can understand the argument that chickens have evolved from dinosaurs or something in between but I was more so asking what evolved first that started it all? Like say .. I've heard some people mention that we started as bacteria
The cells that make up all living things, despite their endless variations, contain three fundamental elements. There are molecules that encode information and can be copied—DNA and its simpler relative, RNA. There are proteins—workhorse molecules that perform important tasks. And encapsulating them all, there’s a membrane made from fatty acids. Go back far enough in time, before animals and plants and even bacteria existed, and you’d find that the precursor of all life—what scientists call a “protocell”—likely had this same trinity of parts: RNA and proteins, in a membrane. As the physicist Freeman Dyson once said, “Life began with little bags of garbage.”
The bags—the membranes—were crucial. Without something to corral the other molecules, they would all just float away, diffusing into the world and achieving nothing. By concentrating them, membranes transformed an inanimate world of disordered chemicals into one teeming with redwoods and redstarts, elephants and E. coli, humans and hagfish. Life, at its core, is about creating compartments. And that’s much easier and much harder than it might seem.
if lungs need a brain and heart to work and a brain need lungs and heart to work and hearts need brains and lungs which evolved first and how did it survive until the rest evolved?
What you’re talking about is called “irreducible complexity.” Necessary organs can develop over time and are only necessary now, to us in our current forms. Organs in their current form may have replaced previous organs, such as gills. If tf the oceans rise - and assuming the species persists - in 100,000 years, we may have developed gills again and no longer possess lungs. An organ that served one function may change to perform another function if its original function is no longer required - e.g. the appendix.
Your body has the leftovers of many body parts that are no longer necessary, some of these remnants are even disappearing over time. They’re called vestigal structures.
If a god can create any form of life it chooses, why would it be limited to creating its crowning achievement, humanity, that has interdependent organs with little to no redundancy? Humans created organ transplants, not to mention artificial organs, to fix this god’s mistake. Why could it give salamanders and spiders the ability to regrow missing limbs, but not us? Why would it create the biological ability to change sex to facilitate reproductive continuity and survival, and give it to frogs instead of us?
For that matter, why would it be limited to creating life on the most temperate planet on the solar system, the one most suited to supporting it in the first place? Shouldn’t a creator god be immune to such limitations, and able to create life on Pluto or Mercury just as easily?
These interdependencies, vulnerabilities, limitations and flaws are a slam-dunk for evolution, and against the idea of a benevolent, powerful, intelligent creator. (Although perhaps not by a malevolent, limited, incompetent creator.)
All of them, and the many other flaws of the human body, are explained by evolution, but not by design or creation.
Also you bring up incest which makes me think of another question, when the first human evolved where did it get it’s mate? Was it a different unrelated fish that happen t evolve at the same time? Thanks again! (:
There was no first human. No creature has ever given birth to another creature of a different species. Speciation does not occur because you’re different from your parents. It’ occurs because you’re different from your great, great, great, great [x thousands of generations later] grand-parents.
i understand why you’re asking it, but with an understanding of evolution, it’s a nonsense question.
