if all countries are able to specialize in producing what they are best at would the world's overall production of good go up?​

by improved communication.

genetics is the study of how dna works, the methodologies defining the new recent technologies allow scientist to have a panoramic view of the entire dna landscape, especially how genomes interact with their environment, including off course, factors outside their organisms.

thus is very possible the existence of both scenarios, where populations of isolated individuals have different genetic traits, and share traits related to genetic mutation, due rats can easily travel overseas using human transport channels. so scientists could get a vast number of data, including human interaction, evolution of rodents, health development, spread of infections, development of new organisms, how genomes evolve in different environments and so on.

the answer here would be

no every country is held to the same degree as others just some member countries such as the usa and germany are more economically sound so the need to show there support to all others
