Chapter 23, Problem 8SQ
Summary Introduction
Introduction: The primates are the only group of mammals that can extensively use their forelimbs for the purposes other than locomotion. Hominins are primates that include humans and their extinct ancestors. Hominins are the group of all extinct human-like species and humans, where they showed the unique characteristic of bipedalism. Human beings and their ancestors are included under the tribe: Hominini. They are the most advanced placental mammals with large cerebrum and cerebellum.

Why is it interesting that Homo luzonensis was found on an island?
A.
The islands only formed after Homo luzonensis became extinct, so Neanderthals must have put them on the island
B.
The islands were a few miles apart, and Homo luzonensis would have needed to either float by grabbing on a tree or make a raft
C.
The islands were a few miles apart, and Homo luzonensis clearly had to learn how to fly to get to them
D.
The islands were volcanoes when Homo luzonensis was alive, so it's unexpected that they were there
What ARE possible explanations for how these individuals got into the cave?
A.
The Homo naledi individuals went into the cave to hunt animals
B.
The bodies were deliberately disposed in the cave by other Homo naledi individuals or other hominins
C.
There was a massacre
D.
The Homo naledi individuals lived in the cave and died there
Which conditions would NOT lead to good preservation of a dead hominin skeleton?
Group of answer choices
A: Dying in a very dry dessert
B: Dying in the marsh alongside a lake
C: Dying in an open grassland that is seasonally dry or wet.
D: Dying in a cave
