Re: Offspring Selfishness changing into Parental altruism?
However, If I was to generalize I would say that in infants, that are not fully developed in terms of hormones, brain structure, cognition etc, there is no grasp of altruism. Evolutionarily speaking it makes sense that infants, that are competing with siblings and have no real use for altruism woul...

Offspring Selfishness changing into Parental altruism?
Hello, I don't know very much about the technicalities of genes and stuff. But, I just had a general doubt about it. Is there any way a gene could change its function (make it opposite, to be precise) as the individual holding it ages? Perhaps something like having one function while the individual ...

That's true...

Evolution of the distinction of gender
For the past few weeks, I've been wondering about why there would be an evolution of gender distinction in animals in the first place. Agreed; there is no "why" to evolution...but "how" did it come about? I just can't imagine a point where hermaphrodite species split into sub-spe...

Similar arguments have been raised by other scientists. People begin to wonder if Darwin's evolution holds after going through what happens at the micro level at tremendous detail. They feel intimidated. How could all of this complexity arise and coordinate with the rest of its micro counterparts to...

I think, seeking for a physical signature of life, we are on a wild goose chase. I think there is no such signature and yet, our logic strives to assume that there is such a thing. Lets take a look at the concept of life with a broad spectrum and try to figure out why it exists today. Let's see how ...

What is life? (Seeking a physical signature for life)
Let us take two organisms A and B that are capable of having life. Let us say that A has life detected in it and B hasn't. Now, assuming A and B are frozen in a frame of time, would there be any physically observable anatomical differences between the two organisms(assuming the difference can be at ...

So, is it true that increasing the blood flow to the entire brain helps in increasing its activty? (Actually, this seems to stem up as a corollary of the fact that the more active an organ, the more oxygen it demands) If it is, then why shouldn't increased bloodflow to one part of the brain increase...

Ununiform blood flow to the hemispheres of the brain
Hello, Perhaps this is a naiive question...naiive because of the lack of my knowledge of the blood circulation system of the brain. Anyway, I was wondering if increasing the blood flow to one hemisphere would improve its activity or dominance (at least temporarily). I came up with this question beca...

***SHIFTS IN BRAIN DOMINANCE***
Hello, I had certain personal experiences in my life that made me doubt if activity induced brain dominance shifts could occur; i.e. Can the nature of work that we do induce (even slightly)changes in our brain dominance? I had this personal experience some time ago, where I had to prepare for a very...
