Crossword Puzzle for Early
Topic 2: Analysis of Early Hominins
3. Bipedalism was very likely an
adaptation to living in this kind
of environment—it provided
advantages for survival.
6. The earliest known species of
robust australopithecine--it lived
about 2.5 million years ago. So
far, this species has been found
only in East Africa. Since it had
a smaller brain than the other
robust species and it was early,
it is thought to be a transitional
form from one of the gracile
species that came before. It had a
very large sagittal crest.
8. A South African robust species of
early hominins that lived about
2.0-1.4 million years ago.
10. The earliest known
australopithecine species. They
lived 4.2-3.9 million years ago in
11. The term for the bones of the hip
12. A species of australopithecine
that lived about 3.3-2.5 million
years ago in South Africa.
Skeletally, they were less ape-
like than earlier species of
australopithecines but were still
usually small and light in frame.
This may have been the last
13. A term applied to the non-robust
australopithecines and the
earliest humans. It means
graceful, slender, and delicate
and is used to describe the body
characteristics (especially bones)
of these species.
14. The genus of all human species.
1. The genus of early hominids that
was most likely the immediate
ancestor of humans.
2. Meave Leakey discovered this 3.5-
3.2 million year old hominin near
Lake Turkana in 2001. She
suggested that it will displace
Australopithecus afarensis as the
progenitor of humans. The name of
this species means "flat-
faced man from Kenya".
4. Two species of late
australopithecines are the leading
contenders for being the immediate
ancestor of early Homo. One of
these is Australopithecus
africanus. What is the other?
5. A species of early
australopithecines that lived 3.7-
3.0 million years ago in East
Africa. Skeletally, they were
still somewhat transitional from
early Pliocene apes.
7. The bony arch extending
horizontally on either side of the
face just below the eyes on
primates and many other
vertebrates. The major jaw muscles
pass under these arches on their
way up to the temporal areas of
the skull for attachment.
9. A super-robust East African
species of australopithecine that
lived about 2.4-1.4 million years
ago. They were more massive and
Australopithecus robustus. While
they were only a few inches
taller, they averaged 20 pounds
