A cell cannot be formed by itself. There is no an intelligence in nature to do that. Neither power nor energy. Let’s assume a very initial cell. How it both could be an animal and a tree or a plant? What decided that? There are uncountless blind points in evolution thought. In faith? There is one and that is God is eternal which we could not comprehend. But every thing points God. First human was a prophet. And first man declared that there is a creator of that world. And many thousands after him supported that by miracles and revelation. Logic say me … There is nothing without a master… from quarks to stars.Are you related to Techno by any chance?
You do not get to define what is, and what is not, evolution. Evolution has an agreed scientific definition:Immunity system could have many improvement and that is not evolution.
Changes in the human immune system are one of those changes in allele frequency that the definition refers to.Biological evolution, simply put, is descent with modification. This definition encompasses small-scale evolution (changes in gene — or more precisely and technically, allele — frequency in a population from one generation to the next) and large-scale evolution (the descent of different species from a common ancestor over many generations).

But pain is only part of the problem. I doubt giving birth is pleasant for any mammal. It’s the higher risk of infant and maternal mortality that the bipedal restrictions on the width of the pelvis (and hence the birth canal), along with the much larger head of humans as compared to other primates that’s the problem. Intelligence has been highly enough selected (due to the obvious advantages) that an increased risk of death and injury from dangerous births is, shall we say, worth it. That’s the nature of evolution. It builds on existing features. It can’t rejig an entire part of the body or organ system in a few generations. By and large, the human body plan is the same as all mammals, indeed all tetrapods, so as ancestral populations became more selected for intelligence, requiring ever larger brains, it meant our ancestors were born more and more prematurely, because bipedalism and big brains are both extremely important to genus Homo.niceatheist:
Setting aside the pelvic shape for one moment, perhaps it would not have been painful for several other reasons, one of which could be the pelvic nerves were less sensitive during childbirth.So I take it you’re not actually going to deal with the physical issues involved in making human child birth relatively more risky than in other primates.

In reality there are two major divisions of life; eukaryotes and prokaryotes (well, some taxonomists think there a three; eukaryotes, bacteria and archaea), along with a whole lot of different kinds of viruses (which we can debate whether they are living or not).
Plants and animals are, taxonomically, very closely related. The cells themselves are structured much the same. all eukaryotes can be recognized by internal membranes around organelles, whereas prokaryotes do not.
Molecular biology is probably the second hardest area of research in biology (behind organic chemistry), but there’s been a lot of work done researching when the kingdoms of life began splitting off, and the kind of “fossils” those evolutionary steps left in the genomes of organisms. In fact, molecular biology is the second strand in mapping back evolutionary processes; hence the notion of the twin-nested hierarchy; which is taking morphology (either of existing species, or the fossils of ancient species) and then overlapping that with the genetic data.
For instance, the development of tetrapods as diverse as lizards, fish and mammals are governed by a very similar set of HOX genes. In a lot of ways, these HOX genes, which seem to signal what happens during cell differentiation in a developing fetus. Changes in these HOX genes over time are what have created the various novelties found among tetrapods, but if you really look at the tetrapod body plan, it’s actually fairly highly conserved, because going too far off script, so to speak, is likely to lead to an organism that, even if it survives in the womb (which major failures in development often don’t), it’s not likely to be viable.
The part of evolution(changing) I reject is the evolution between species(“large-scale evolution (the descent of different species from a common ancestor over many generations”). There is no such thing. There is no intermediary forms. There is no fossiles which support that. With modification a new species do not consist. Immune system or others system could accord or adjust something according to new conditions. But that systems do not transform into another. That is not evolution(which you mean generating new species).Immunity system could have many improvement and that is not evolution.
As I mentioned a cell cannot be consist by itself. Let allow all scientists gather and work for years. Will they be able to invent an alive cell by combining oxygen, nitrogen, carbon, hydrojen and other required atoms one by one? Is that possible? If it is not how it could be by itself with random conditions and unconscious power and blind and dead energy and destructive other parts of nature? And that cell(just an assumption) do not transform into another species. Aaaaa…it is not proved. Just a thought(theory)!
How many cells got formed by random chances? One? If it was one so how could thousands species emerged from that unique cell! If you could change a mouse to a cat. If there were more so why do not new ones occure? There are more suitable conditions now!
What about those with bigger heads yet?But pain is only part of the problem. I doubt giving birth is pleasant for any mammal. It’s the higher risk of infant and maternal mortality that the bipedal restrictions on the width of the pelvis (and hence the birth canal), along with the much larger head of humans as compared to other primates that’s the problem. Intelligence has been highly enough selected (due to the obvious advantages) that an increased risk of death and injury from dangerous births is, shall we say, worth it.

But doesn’t common sense tells us that the bigger heads (assuming big heads correlate to higher intelligence) who die in child birth or do not reach puberty never get an evolutionary chance to reproduce and demonstrate the advantages of that higher intelligence? Evolution cannot build on improvements that never reproduce.Intelligence has been highly enough selected (due to the obvious advantages) that an increased risk of death and injury from dangerous births is, shall we say, worth it. … That’s the nature of evolution. It builds on existing features.
No. It does not/But doesn’t common sense tells us that the bigger heads (assuming big heads correlate to higher intelligence)
First, there need not be any intermediary forms. A single mutation can result in a new species. See The marbled crayfish (Decapoda: Cambaridae) represents an independent new species for one example.There is no such thing. There is no intermediary forms.

Because it came way before so it could not be an intermediary as evidenced by the dating of the tracks found in Poland.Tiktaalik for example. Why do you reject Tiktaalik as an intermediary form between fish and amphibians?
You are using the wrong definition of intermediary. We know that Europeans exist today. Does that mean the no Americans can be descended from Europeans because Europeans still exist?Because it came way before so it could not be an intermediary as evidenced by the dating of the tracks found in Poland.
Uh no. The first one was dated well before the intermediary was purported to be.You are using the wrong definition of intermediary. We know that Europeans exist today. Does that mean the no Americans can be descended from Europeans because Europeans still exist?
What does not – makes common sense or the truth of the assumption?No. It does not/
