Anthropologist have pieced together the little they know about the history of left-handedness and right-handedness from indirect evidence. They did leave tools, bones, and pictures. Stone Age had axes and hatchets were made from stones that were carefully chipped away to form sharp cutting edges. In some, the pattern of chipping shows that these tools and weapons were made by right-handed people designed to fit comfortably into a right hand. Other Stone Age implements were made by or for left-handers, prehistoric pictures, painted on the walls of caves. provide further clues to the handedness of ancient people. A right-hander finds it easier to draw faces of people and animals facing toward the left, whereas a left-hander finds it easier to draw faces facing toward the right. Both kinds of faces have been found in ancient painting. On the whole, the evidence seems to indicate that pre4historic people were either ambidextrous or about equally likely to be left-or right-handed
But, in the Bronze Age, the picture changed. The tools and weapons found from that period are mostly made for right-handed use. The predominance of right-handedness among humans today had apparently already been established.

After help, we can use object + infinitive (with or without to).
| Can you help me (to) find my ring? (NOT | |
| Thank you so much for helping us (to) repair the car. | |
| Our main task is to help the company (to) become profitable. |
Help can also be followed directly by an infinitive without an object.
| Would you like to help pack? |
If you say that you cannot/can’t help doing something (especially in British English), you mean that you can’t stop yourself, even if you don’t want to do it.
| She’s a selfish woman, but somehow you can’t help liking her. | |
| Excuse me – I couldn’t help overhearing what you said. | |
| Sorry I broke the cup – I couldn’t help it. |
Can’t help can be followed by but + infinitive (without to), with the same meaning as can’t help verb + ing. This is common in American English.
| I can’t help but wonder what I should do next. |
