Australopithecine Afarensis, an early hominid, lived in shelters as they found them. Caves, if available , trees if need-be , primitive lean-to type things that had some natural beginnings.Thickets that had thorns would keep predators from having easy access. Just in small goups on the ground when no real shelter was available. Look up Lucy, the most famous early hominid skeleton found for more info on this fascinating possible relative to homosapiens. [That's us]
FYI for our members of faith. I have no problem with having Creationist and Evolutionist beliefs concomittently, within species groups.
they used trees
The Australopithecus lived mainly outdoors and either foraged or hunted for its food. They took shelter in tall trees. The Australopithecus lived in woodland areas of Africa about 3.8 million years ago.
Australopithecus likely slept either on the ground or in trees, as they were biologically adapted for both arboreal and terrestrial lifestyles. They may have curled up or laid on their side to sleep, similar to other primates. The exact sleeping position would depend on their habitat and the availability of trees for shelter.
shelter belts
No, koalas do not build shelter. They shelter in eucalyptus trees, resting in the forks of trees or on branches, but they neither build shelters nor do they use hollows or other forms of shelter.
They sleep in trees because of lions and other animals that can eat them so they sleep in trees so big animals don't eat them.
Grasshoppers use trees, leaves, and other plants for their shelter. They rest or sleep for short periods of time on a branch or a bush.
The Australopithecine were very much like Homo sapiens. Most of the time they traveled in groups. They were social, friendly ape-like humans. Their shelter was the nature around them, for example trees, rocks and cliffs. The Australopithecine created 2 other homo- species that evolved even more.
other herbivores
trees
Australopithecus is one of the longest lived early human species. They survived for more than 900,000 years, they had ape and human characteristics and lived both on the ground and in trees.
Koalas only shelter in eucalyptus trees. They may be seen in other species, but their homes are always in eucalyptus trees. They do not use tree hollows, nor do they make nests. Koalas nestle in the forks between trunk and branches, and shelter within the branches and leaves. This gives them adequate protection from all kinds of weather.
