I had all four wisdom teeth and they were impacted. Also, grew in horizontal, fully covered too.
The hymen is there to keep bugs out.
UGH! that sucks! :jawdrop:
yep, boy cooties
actually if the resurch i herd about recently is right the apendix is VERY important. The theory goes that we are causing cancers and other problems because we keep killing off the gut flora (with antibotics). Now if that resurch is right then the implication is that the apendix is important because everytime you get diahrea you lose all your gut flora and the apendix alows it to be repopulated.....
...Appendix - likely a vestigial cecum, needed when we ate more cellulose. Nowadays since we cook our food (and generally eat easier to digest food) it's not needed....
are you sure billvon?
Also, i would add, since humans evolved (in theory) form much simpler form why would parts be added and then taken away?
Can anyone come up with other parts lost through evolution?
Two issues i have with the longer thumbs theory:
Thumbs are delicate protrusions and painful if broken plus they dont grow back like fingernails. As an aside, wouldnt it take millions of years, or at least thousands, then wouldnt it be safe to assume that by the time the change was fully implemented texting would be loooong gone?
Because they are no longer needed. It happens all the time; fish, for example, will lose their eyes if they remain in dark caves for long enough. Eyes are no longer needed so they are evolved away.
A bigger jaw is also a vestige of excessive cud (veg matter) chewing.Thank you Bill.
I was just wondering why the head would evolve to have them to begin with...the extra teeth, i mean. Only to evolve to a smaller head anyway and also a larger brain for the smaller head.:shrug:
My question is why evolve larger to begin with?
