Demolishing established shibboleths

Subject: Demolishing established shibboleths 

The prowess of black people in athletics is amazing. Watching Dina Asher Smith strike for home in the final of the 200m sprint, one has, over the last 30 years, (more if you take the USA into consideration), seen the domination of athletics by black athletes. Initially the sprint competitions but now across the board, black athletes leave white athletes trailing in their wake. The are exceptions like the Ingebrigtsen  bothers in the 1500, 3000 and 5000m, events where they win or are near the front and Kirsten Warholm the young Norwegian hurdler, best last year and also this year but these are the standouts in a sea of black faces. 
In the sprints it's the terrifying physic of the black male sprinters as they line up on the starting blocks, muscles rippling, huge torsos, explosive power which the white athletes seem to come a poor second. Black women also completely dominate the  sprint events, their power to weight ratio seemingly unstoppable. 
In the long distant black runners, men and women from Kenya and Ethiopia seem light years ahead of their white counterparts, especially so in the marathon where the black athletes turn most races into two sections, the black runners at the front and 200 yards and more behind, the first white runner. 
Now I know some of the more squeamish of you will feel uncomfortable with any sort of black /white analysis claiming we are simply members of the human race and it's racist to differentiate on the basis of colour but of course underlying the observation that black people do so much better than white people one is entitled to ask why. 
In the field events such as discus, javelin, shot put and hammer throwing it's the reverse with white athletes predominating. Could it be simple a matter of the cultural attraction to these field events shown by largely Central European athletes both male and female and that the interest hasn't yet been sparked amongst black people. 
Physiology plays a part, living at altitude plays a part, mental attitude plays a part but the change since the days in the 50s, the days of Roger Banister, Emil Zatopek, Vladimir Kuts where white athletes dominated the long distance events and only in the sprint events with Jessie Owens cocking a snoop to Hitler and his Aryan obsession, and then  the Black Power salute on the podium of the 1968 Olympics by the two winning black athletes, Tommie Smith, John Carlos  and the Australian athlete Peter Norman who although White wished to make a stance against discrimination, it was an image that shocked the athletics world.
Like a more recent event where four black American Footballers knelt whilst the anthem was played, (also a reflection against discrimination), to which the establishment took a very dim view and, in the case of Smith and Carlos they were never picked again.
Today everything is changed, white athletes, by and large play a secondary role and with few exceptions, the gap seems to grow. 
Is it in the genes, is it because the huger to succeed is more easily won in athletics than in other fields of endeavour, (although the academic pass rate is exploding out of the Asian boys and girls attending school),  watching Dina Asher Smith and later in the Heptathlon,  the equally young Katarina Johnson Thomson stretch out and demolish the other competitors one has to reflect on this changing world and the frailty of establish shibboleths.
