Other than height, are there any observable physical differences between a human who is alive today and someone who was alive 10,000 years ago?

To get an idea of this, when Europeans sailed to the Americas and Austrailia, they met people who had been genetically isolated from them for more generations than you have from a person 10,000 years ago.  On a fundamental genetic level there's basically no significant difference.

Now, they might look a bit different from their descendants (for example, Europeans have gotten paler over time), but they'd be well within the range of modern human variation.  Obviously they'd be wearing a different set of clothes and probably looking around wondering what the heck had just happened if you saw one transported straight out of the stone age.

Non visible differences might be present too.  They'd lack a set of genes that many (but not all) modern humans have making it easier for us to digest farmed foods like milk, starches, and alcohol.
