b. <em>Homo neanderthalensis</em>
Explanation:
<em>Homo neanderthalensis </em>are extinct species of the Homo genus which lived in Eurasia until 40000 years ago. They initially lived in Europe and then migrated to Central and Southwest Asia. Compared to modern humans, they had shorter legs and bigger bodies.
They have been known to construct huts out of mammoth bones. Archaelogists discovered a Neanderthal hut structure made of mammoth bone which is considered to be 44000 years old. This structure was 26 feet wide and mostly used for domestic purposes. Previously <em>Homo neanderthalensis </em>were considered primitive creatures who lived in natural caves but after this discovery it has been accepted that they were also advanced.
