Evolution and technology

It is the technology affecting the human evolution?

The influence of the technology in human beens is huge and trascends to a biological level, there exist many people interested on clarify this problematic that affects most of the world.The access to the technology  is, obviously, different in all the countries ,  some places for example in Africa   haven´t the resources to cure diseases that cause the dead of a lot of people,compared with others countries with a better economy .Nevertheles a considered ammount of poblation that live in this "poor" countries are immune to sickness ,wich are mortal to  people of "developed" countries,so it surge the idea of a parallel or co-evolution of the human been.
The biological anthropology expert Jay T.Stock has approached to this subject ,writing the article "are humans still envolving",and he purpose the concept of micro evolution and co-evolution.He refused the idea that the development of technology throught the human history has cause the cease of the evolution ,because how it mencioned previously there still appearing little changes in human morfology wich depends of the geographic zone,Stock called this a microevolution and it's directly associated with the technological advance.
To complement previous studies i consider that the most appropriate way of prove this teories is examinating and comparing different geographic zones around the world ,and those have to present economic differences ,then i should have to analized the people that live there,making any kind of corporal exam.
 To conclude i think the socio-economic differences are making the human race more and more heterogeneous biologically.
