Iposted this an hour ago but nobody even looked at the three questions, 1. what did john w. mackay and george hearst have in common? 2. how did the speculators price land during the gold rush? at what price was the ophir quoted? 3. there were many drawbacks to industrial mining. name one.

John William Mackay (November 28, 1831 – July 20, 1902) was an Irish-American industrialist. Mackay was one of the four Bonanza Kings, a partnership which capitalised on the wealth generated by the silver mines at the Comstock Lode. (i copy pasted fyi ;p)

b) that he was not a free man

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.
