Question

Which biologist was the first to show that almost all the Australian mammals were marsupials?

• A. Friedrich Wilhelm Humboldt
• B. Sir Joseph Banks
• C. Charles Darwin
• D. Franz Joseph Gall

Answer 1

The correct option is B Sir Joseph Banks

• Australia is the only continent (and one of the only two countries - the other being New Guinea) in the world to still have all three of the major groups of mammals: monotremes, marsupials, and placentals
  
• Half of Australia's mammal species are marsupials (South America has a few dozen species - all in the opossum family - and a couple of species have found their way into North America, but Australia is the only continent to have such a diverse range or to have marsupials as their most common and conspicuous land mammals)
  
• Sir Joseph Banks was one of the first to describe the Australian marsupial, the wombat.
  

So, the correct answer is 'Sir Joseph Banks'.
