John wycliffe considered the bible/church , not the bible/church the only true measure of christian conduct.

Correct answers:  John Wycliffe considered the BIBLE, not the CHURCH, the only true measure of Christian conduct.

This was a main idea shared by Wycliffe and other Protestant reformers, that the Bible is the ultimate source of truth.  They were objecting to the way that the Roman Catholic Church asserted the authority of the popes and church traditions to be of the same value as the Bible.  Reformers like  John Wycliffe in England and Martin Luther in Germany made efforts to translate the Bible into the language of their own people for people to learn God's truth for themselves.

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.
