I've noticed in all my relationships, and in many others, when women hit a certain comfort level with their boyfriend and in their relationship, the mother in them starts to come out. Things like nagging, nitpicking, worrying about what we men would consider trivial things, etc.
I was wondering, why does this tend to happen? And I don't mean what are women thinking consciously while they do it, but what is going on unconsciously? Where did this tendency come from, psychologically or biologically speaking?

Was there romance in the proverbial "caveman" days? If so, how has it changed and what was its (evolutionary/psychological) purpose? How has it changed? If not, where did it come from?

Topic :-Vestigial organs not necessarily proof of evolution for Darwin


I would postulate that it is possible to have a vestigial organ [ananatomical structure in organisms in a species, thought to have lost its original function through evolution] without the process of evolution. Let me illustrate this idea using an analogy drawn from popular computer software.

Assuming, I have a reasonable amount of storage space on my computer hard disk, if I first create an unformatted document using Microsoft(MS) Word, and then a second MS Word document that I format very rigorously, I do so because I consider MS Word software to be the best option for my purposes, as opposed to using, say, the less sophisticated Notepad software, where little formatting of documentsis possible.

Now, if you argue that there is a vestigial structure to the first MSWord document (the capacity - in this case, unused - for formatting)and that this only became functional in the second document,ultimately concluding that the first document evolved from the second document, you would be incorrect, since I am the creator of both documents.

Similarly, I would argue that vestigial organs do not necessarily confirm evolution; they only point to what tools - improvable overtime - the creator used while making the species. This same principle is seen even in electronic gadgets today.

Most probably, such an explanation did not occur to Darwin given that, in his time, there were no common tools to carry out varied, complex,seemingly disconnected jobs. So he concluded that unless a creator planned to mislead us, vestigial organs should not have existed

It is tendency of creators of to make some useful common tools, which can be used to carry out multiple jobs (or to make machines). so by virtue of this comman tools (if tools get fitted into machines), vestigenesity will come up.


Vestigial organs can be classified in to verticle & tranverse ones

Verticle ones are like appendix which are inherited from ancestor to next species

Tranverse one are in which one sex has fuctional capacity & in opposite sex it is vestigineous

Example
Vertiginous Male breast can be better explained tools of intelligent design than Darwin evolution now look at male nipple which are functional in female. Male & female have come much before mammals, so presence of male nipple in mammals can be explained by theory of tools of intelligent design better than Darwin evolution.

No organism has a better chance of surviving than any other organism.


Adaptations that help an organism in one environment may hurt it in another.


It's impossible to guess how an organisms' adaptations helped it survive.


Organisms manage to reproduce purely by chances.
