Yeah because in the 40,000 + years before that people lived in peace an harmony and didn't smash each others heads in with rocks.
No they used bows and arrows, and spears.....

That's the exact opposite to how it is and how physics works. A larger calibre round has LESS penetration for a given amount of kinetic energy because the larger calibre causes greater tissue deflection and more hydrostatic-shock. a 7.62x51 FMJ round is SIGNIFICANTLY less likely to simply "pass through" a target than a 5.56x45 FMJ.
America forced NATO to adopt the 5.56x45 round as the new standard riflemans round because it is cheaper to produce, weighs less so the individual soldier can carry more ammunition and other materiel and most importantly, because the round delivers a lower-recoil impulse making it more accurate in all modes of fire, as well as less demanding on the individual soldier and most importantly, allowing the weapon to be less heavily built, making the weapons themselves lighter and cheaper.
the 5.56x45 round has perfectly acceptable lethality at average combat distance when the targets are not wearing level III armour or greater.
I'm loving the experts in this thread.

You may need to make alterations and changes to physical features to accommodate disabled employees. If the physical feature puts disabled employees at a substantial disadvantage compared with your non-disabled employees, you must take steps to adjust it so as to remove or reduce its impact. These alterations are called reasonable adjustments.

Trying to be cronological -
Flint Tips for cavemen (better than sharpened wood)
Bow & Arrow (doen't matter which type it's the concept of a long range weapon)
Gunpowder (cannon/firearms)
Cannon armed Ships
Encased bullets (leads to magazine feed, greater ROF, better reliability)
Aircraft
Maxim machine gun
Chemical weapons
Aircraft Carrier
Nuclear weapons
Guided weapons
I think that'll do for me
Good post. Although as I said earlier the application is slightly different and the 7.62mm was not replaced by the 5.56mm as Thesaff said and as such is not really suitable for inclusion in the OP.
oh indeed, the 7.62 is still in use, but as far as i'm aware the US forces currently only use the 7.62x51NATO round in the following troop weapons:
M24SWS
M40SWS
Mk.11 SWS
M240B and variants
Mk.48Mod0
M14 and variants
and these weapons make up a very small percentage of the forces.
5.56 is a NATO standard, before that there were different standards across the forces, ammunition standardisation has been one of the key influences on modern warfare, you only have to look at the American civil war for the benefits of this. The 5.56 was also chosen because of its injuring capabilities, changing in some way what the weapon is designed for.
Napalm.
