Evolution of humans appears parallel to the progressive development of brain and language skills. As such, the evolution of individual species, in the sequence of their appearance is:

• A
  $Ramapithecus \rightarrow Homo \ habilis \rightarrow Homo \ erectus \rightarrow Neanderthal \rightarrow Homo \ sapiens$
• B
  $Neanderthal \rightarrow Ramapithecus \rightarrow Homo \ habilis \rightarrow Homo \ erectus \rightarrow Homo \ sapiens$
• C
  $Homo \ habilis \rightarrow Homo \ erectus \rightarrow Ramapithecus \rightarrow Neanderthal \rightarrow Homo \ sapiens$
• D
  $Homo \ sapiens \rightarrow Ramapithecus \rightarrow Homo \ habilis \rightarrow Neanderthal \rightarrow Homo \ erectus$
