Yes, but there's a key difference with humans, and we can verify it from our own experience.
Just consider all the members of our extended families, OK, including in-laws & out-laws. ;-)
Now, we readily admit that some are smarter than others, right?
And some are more athletic, others musically inclined, some more adept with numbers, others very good with people, etc., etc.
Point is: for humans there's a wide range of talents & abilities within our own families & "races".
And, so it turns out, this range is greater within our groupings than are the averages between most groups.
For example, within most normal populations we can find individuals with IQs of 80 to 150, a huge spread.
But most "races" average out to about 100, plus or minus a few.
And many groups have experienced steady increases in IQ over many years, suggesting there's more to it than just genetics.
Bottom line: "race" is far from the greatest factor contributing to the many differences we see amongst humans.

“And many groups have experienced steady increases in IQ over many years, suggesting there’s more to it than just genetics.”
What it suggests to me is that the people who have been saying since the 1970s that IQ tests are racially biased have made progress in biasing them toward blacks.
