I have received an answer from a Professor of Biology that says 'species are populations of similar individuals and not cells, be they egg or sperm, produced by these individuals. This obviates my theory, that every individual of any species starts as a single cell, the haploid egg, n, with a single...

Re: Brain size=IQ level theory (Blacks vs Whites & Asians)

There is only one brain, the human brain. It can be larger or smaller within the normal human range; its dimensions (weight, depth, circumference etc) are a rough summary of samples of the adult brain and, of course, there is the surface area, with multifarious complex folds. There can be no 'black'...

Re: Brain size=IQ level theory (Blacks vs Whites & Asians)

All research involving 'races', 'populations', 'groups 'ethnicities' and so on fails to have validity because the subjects of the research cannot be defined or put into boundaries. I have just looked at some research regarding the Y-chromosome, 'Prospective assessment of Y-chromosome micro-deletions...

Re: Evolutionary Origin of Penile Reproduction

However it happened (not, obviously, with the help of magic spirits) each species starts as a cell with its own, complete set of chromosomes, n, unique to it and found in the egg (ovum). Bacteria still represent this kind of species and reproduce by mitosis (simple splitting). Each subsequent indivi...

Re: Brain size=IQ level theory (Blacks vs Whites & Asians)

I cannot find my recent reply so I am making the same point again. All the voluminous and detailed research on this subject is destroyed by one vital problem. When researching the brains of different 'groups' of humans, ('races', 'populations') how do researchers choose their subjects? In other word...

Re: Brain size=IQ level theory (Blacks vs Whites & Asians)

There is one big problem which destroys all the 'well-researched' material and even the very heading of this topic. When using people for the kind of research mentioned above, how do researchers choose their subjects? In other words, who is an 'Asian', who is an 'African' and who is a 'European? And...

Re: Is life only a system of evolving chemical reactions?

Actually, life is just a distant repetition of the burning of gases that make our sun. Our planet was formed when a mass of burning gas was thrown off by the sun and, although cooling on the outside, has remained a molten mass on the inside. Cells, of which life is formed, are tiny bags of H2O and a...

Re: Eye color heredity

Eye colour is simply the amount of melanin in the skin. There is a range of strength in the normal human DNA, the basic 'colour' is black, when the strongest amount of melanin is being produced. As the strength of this process has grown weaker, less melanin is being produced, so the 'colour' appears...

Re: Thickness of Eyebrows (Genetics)

Eyebrows, like every other feature of humans, are on the human range of strong to weak growth. The range is thick eyebrows (strongest growth) to thin (weakest growth). You will 'follow' your nearest 'contributor's' strengths to some extent (your parents) but all growth is within the normal human ran...

Basic Facts: A Better Definition of Sexual Reproduction

As a layperson with an interest in speciation I want to present my definition of Sexual Reproduction. Every species can be defined by the haploid ovum (complete set of chromosomes = n ), humans having 23. This is the new individual at the start of its life cycle. Billions of such species still exist...
