If you look at the results in the Olympics in the past, runners from places like Kenya or Ethiopia didn't dominate in the distance running events until around the 1990s and later. Why was this domination so recent even though these countries always had a ton of talented runners?
Its not really that recent; they have been dominating for the past 40 years (since the 80s). This is about 50% of the time we have had modern athletics and 33% of the time since the re-establishment of the Olympics in 1896.
