Camels are peculiarly adapted for life in desert or Camels are adapted to life in desert ? Which one is correct? and why?

Camels are peculiarly adapted to life in a desert. / Camels are adapted to life in a desert. 
Both the sentences are correct (article 'a' has been added).
Better sentence is : Camels are peculiarly adapted for life in a desert.
The word 'peculiarly' means 'especially'.
'Adapted to' (not 'adapted for') is the correct phrase as it means something has changed to fit its environment.
