I was thinking of the 9 species of New Zealand Moa, a bird that dwarfed the
largest living bird the ostrich; it stood 12 feet tall and weighed well
over 500 pounds. I was also thinking of the Haast Eagle, the largest eagle
that ever lived; it had a 10 foot wingspread and weighed between 33 and 36
pounds. It went extinct in 1400, about a century after the Maori people
first settled in New Zealand when their principle food supply, young Moas,
were hunted to extinction.

It doesn't take long for new species to develop, the Galapagos Islands are
made of some of the youngest land on this planet and yet they contain
animals found nowhere else.

Why bother to ask me that? If you think I'm a liar you won't believe me
when I say I'm not a liar.
