How does 矢 look like an arrow? I find it hard to imagine how the character 矢 looks like an arrow (perhaps a &quot;big&quot; man with a spear on top of his head, I dunno).
Can someone please explain this in terms of oracle bone scripture character evolution, Unicode characters or something?
The character 丢失的失 also looks similar, and might be related. Not to speak about 矮子的矮 where arrows 矢 are shorter than spears (not sure what character you'd user for a spear), women 女 on average shorter than men, and grains 禾 smaller than X, can't remember what X is.
Chinese characters originally looks more different when written in older script, e.g. Oracle Script, as stokes get simplified more and more and curvy strokes are then converted to straight lines and boxy characters, eventually, different characters look alike.

According to http://www.chineseetymology.org, 

矢 originally looks like this in Seal Script:




  Primitive pictograph 矢. An arrow. Meaning arrow.


失 originally looks like this in Seal Script:




  Augmented pictograph 失. Augmentation 丿(something lost) to hand 手 indicating dropping something. Meaning lose.


And for reference, hand 手 in Seal Script:
