We have inherited something from our parents. It is encoded in our genes and we are expressing it. Can we change it during the course of time as we live on.
As is is always said, work hard and you will get results. Isn't it the stressed condition for our cells or is it the happy environment for the cells? Scientifically, more specific biologically?
What makes the cells and finally ourselves think that we are capable of doing something which we found difficult at some point of time.
Is IT EVOLUTION? Or, REALLY WE HAVE CHANGED OUR CODE WITH A MUCH SLOWER RATE?
Actually, the inherited genes can be changed. It is done by dedifferentiation, which is not found normally in biological system, because it is mostly done by cancer cells. Dedifferentiation removes the methylation regions (inhibited regions) from the gene, and when it differentiates again, the formed cells may not be the same (mostly they are not). It is also done in our germ cells (sex cells) to form as much diverse genetic entities as possible. And lastly, stem cell approach can overcome some problems in genetic manners, which is done by changing the genes on some stem cells (using recombination techniques) and also forming a required niche for these cells to forms the desired tissue. Unfortunately, for now, it is not yet possible to form complex tissues from stem cells, but it is an idea for future.
Now, coming to your last question, it is not actually as in cellular level as you think. Because learning in higher level organisms as ourselves, is done by forming new synapses between nerve cells, since these cells are responsible from information (coming from brain) - to work (by muscles) axis. But whether it is called evolution or learning... I don't actually now.
That would be a short summary of the things you asked.
I wish it was clear,
Cheers.
I think the answer is definitely no. When we do some cell biology research , we culture cells . We know how hard it is to change stem cells or even a particular cell line's fate. Not to mention the fate of ourselves. Although we could evolve a little bit. Eventually our fate are determined by God.
Defiantly you can change it, even by gene therapy it is a bit difficult right now but will be feasible after some time. Second thing environmental factor also influence the gene expression so if u control your environmental factors surely u can change your proteome without changing your genome
@SCM: Science has not evolved so much that it can answer all the questions. May be one day you can get answer for the FATE stuff also.
