Piebald horses around humans are like this (7)
I believe the answer is:
bipedal
'humans are like this' is the definition.
(I know this)
'piebald horses around' is the wordplay.
'horses around' indicates an anagram.
'piebald' with letters rearranged gives 'BIPEDAL'.
(Other definitions for bipedal that I've seen before include "Two-footed" , "Walking on two feet" , "Like human" .)
