Answer 2

Answer:

• Approximately  7  crore years ago,  the  dinosaurs  disappeared  completely.
•  At that  time,  monkey like  animals appeared  from  more  or less similar to  the  modern lemurs.  
• Tail  of  these  monkeylike  animals disappeared  about  4  crore  years ago.  
• Due  to enlargement  of  brain  and  improvement  in  their  hands,  apelike  animals were evolved and  then  later they  evolved  into  gibbon  and  orangutan.
