Ancient relative’s northeastern heartland destroyed (11)

I believe the answer is:
neanderthal
'ancient relative's northeastern heartland destroyed' is the definition.
I can't tell whether this defines the answer.
'northeastern heartland destroyed' is the wordplay.
'northeastern' becomes 'ne' (abbreviation for northeastern).
'destroyed' indicates an anagram.
'heartland' is an anagram of 'anderthal'.
'ne'+'anderthal'='NEANDERTHAL'
Can you help me to learn more?
(Other definitions for neanderthal that I've seen before include "Hominid discovered in Europe" , "Extinct type of human" , "Uncivilised man" , "Type of primitive man" , "Sort of very old man" .)
