If we cloned ancient human DNA would they be deficient today?

If we got the go ahead for a worldwide project to clone hundreds of ancient humans in say 5 groups of 10k years old, 5k years old, 2k, 1k and 500 years old, and raised them as normal children would they have a harder time in school?
How much different is our brain today than 2k years ago? Is 2k years of "evolution" indistinguishable?
I look at things like eyesight and height and see that they can change in little to no time:
example eyesight
example height
I know a quick rebuttal may be "external forces" ie. Computer/reading more.common (eyesight) and medicine & nutrition advances(height) but I not completely convinced that there isn't some adaptation/evolution going on as well.
So the question, if we grabbed your 10k year old ancestors DNA, would you expect them to be as normal as anyone today?

About 30 per cent of Hongkongers born before 1950 are myopic, according to a report by the Centre for Myopia Research at Polytechnic University, but that rate shoots up to 70 per cent for those born between 1950 and 1980.
example height

In fact, over the last 150 years, the average height of people in industrialized nations has increased approximately 10 centimeters (about four inches). In the first half of the 18th century, the average height of an English male was 165 cm (5 ft 5 in)

I got a feeling cloning our ancestors from 10k years ago would put a big ol fat anchor around the neck of the “we’re all equal” crowd.

I would assume their immune systems (or lack there of) would get them killed.

We got enough of those cave men running around today...

You answered this one in your OP.

The biggest change in height is because of better nutrition over the past 150 years. For a long time Americans were among the tallest people on earth because of our superior nutrition that’s provided by our farming. Now, however, most of the world has access to good nutrition and many nations’ populations can achieve the maximum heights that their genes are programmed for. In short, it isn’t evolution, just better food.

if we went back 50k to 80k years ago? How about 150k to 400k years ago. How many thousands of years back into human evolution would we have to clone before you would definitely say...."yeah, they would struggle?"

I have no feedback to provide, but this is actually a pretty damn interesting thing to think about.

I would think so as well. No immunity to a lot of things we have immunity to over the years would be a hard thing to overcome.

Well, 2k years ago people built Rome without computers and modern equipment, so I don’t think they were lacking intelligence. I think the Sphinx is dated to something like 4k years ago. I have a feeling you would have to go back pretty far before you started to see lack of capacity in intelligence.

I figure their immune system can probably handle a polio shot too.

I’m sure the great minds that brought about the engineering feats such as the wheel would excel in modern day civil engineering.

The folks that built the pyramids are more than welcome to come back and build some new interstates and highways

Chimps and gorillas can learn sign language and how to use tools, and Koko the gorilla supposedly had an IQ of 75+ and could understand 2,000 words. If they can learn that much with brains 1/3rd the size of ours, I don't think a human from 100k years ago would have any trouble at all learning what we know.

genetically, by the code, there'd prolly be very minor differences.
epigenetically it'd be off the scales. their genes expressed because of environmental factors, and those of their parents and grandparents would be drastically different.

Not really how immune systems work. They’ll need help as an infant but it will be more due to the artificial nature of birth than a genetic deficiency (mother’s immune system confers a life raft of acquired immunity for around the first six months after birth).

It would be Africa

No, they would be mostly the same.
