The Origin of Humans Flashcards
are the members of
the Hominoidea superfamily of primates, which
includes humans.
Apes
Under current classification, there are
two families of hominoids:
- Hominidae (chimpanzees, bonobos, oran
gutans, gorillas, and human beings). - Hylobatidae (gibbons)
is the tribe of Homininae that only includes humans (Homo), chimpanzees (Pan),
and their extinct ancestors.
Hominini
is a Latin word meaning ‘human’ or
‘man’.
Homo
is a class of similar things, especially a group of animals
or plants that includes several closely related species.
genus
-any of a family (Hominidae) of erect bipedal primate mammals that includes recent humans together with extinct ancestral and related forms and in some recent classifications the great apes (the orangutan, gorilla, chimpanzee,
and bonobo)
Hominid
the group consisting of modern humans, extinct human
species and all our immediate ancestors (including members of the genera Homo, Australopithecus, Paranthropus and Ardipithecus).
Hominin
means ‘southern ape’ and was
originally developed for a species found in South Africa.
Australopithecus
The word
___________is based on the location where some of the first fossils for this species were discovered – the
Afar Depression in Ethiopia, Africa
Afrensis
the first modern humans, evolved from their early hominid predecessors between 200,000 and 300,000 years ago. They developed a capacity for language about 50,000 years ago.
Homo sapiens
is part of a group called hominids, which were the earliest humanlike creatures.
Homo sapiens
The theory that hominins were forced out of the
trees they lived in and onto the expanding savannah; as they did so, they began walking upright on two feet
Savannah Hypothesis
the condition of having two feet or of using only two feet for locomotion.
Bipedalism
is a process that results in changes in the genetic content of a population
over time.
Evolution
The first fossils attributed to Homo erectus were discovered by a Dutch army
surgeon
Eugène Dubois
in biology, the dying out or
extermination of a species
Extinction
Though there were once many kinds of hominids,
only one remains:
Homo Sapiens
We do have some clues as
to why some species were less successful at
surviving than others, such as an inability to
cope with competition for food, changes in
climate, and volcanic eruptions.

The name Homo sapiens was applied in 1758 by the father of modern biological classification
Carolus Linnaeus
__________ is one of
several species grouped into the genus Homo, but it is the only one that is
not extinct.
Homo Sapiens
Scientists studying land masses and climate know that the Pleistocene Ice Age created a land bridge that connected
Asia and North America (Alaska) over 13,000 years ago. A widely accepted migration theory is that
people crossed this
land bridge and eventually migrated into
North and South America.

Donald Johanson in Hadar, Ethiopia
Lucy’ AL
The theory that the savannah was expanding due to increasingly arid conditions, which then drove
hominin adaptation. It suggests that early hominids were more suited to
dry climates and evolved as the Africa‟s dry
savannah regions expanded.
