Practice Reading: Fill in The Blanks (Drag & Drop) ID: #31612 Colourful Poison Frogs
Instructions
* Drag the correct answer into all target fields
Colourful  poison  frogs  in  the  Amazon  owe  their  great  diversity  to  ancestors  that  leapt  into  the  region  from  the  Andes  Mountains  several  times  during  the  last  10  million  years,  a  new  study  from  The  University  of  Texas  at  Austin  suggests.  This  is  the  first  study  to  show  that  the  Andes  have  been  a    source  of  diversity  for  the  Amazon  basin,  one  of  the  largest    of  biological  diversity  on  Earth.  The  finding  runs    to  the  idea  that  Amazonian  diversity  is  the  result  of  evolution  only  within  the    forest  itself.
"Basically,  the  Amazon  basin  is  a  melting  pot  for  South  American  frogs,"  says  graduate  student  Juan  Santos,  lead  author  of  the  study.  "Poison  frogs  there  have  come  from  multiple  places  of  origin,  notably  the  Andes  Mountains,  over  many  millions  of  years.  We  have  shown  that  you  cannot  understand  Amazonian  biodiversity  by  looking  only  in  the  .  Adjacent  regions  have  played  a  major  role.
