The theory that species persist for long periods and then
undergo rapid spurts of evolutionary change is:
If fossil species A is consistently recovered from geological deposits beneath layers containing fossil species B, then A is considered older than B. This relative dating technique is based on the principle of:
One of the only fossil sites in the world that preserves a great deal of evidence for anthropoid evolution during the Eocene and Oligocene epochs is:
Prior to the invention of absolute dating techniques, one of the chemical dating methods useful for establishing the relative age of fossils from a single site was:
Biostratigraphic dating relies on:
the first and last appearances of species in the fossil
The absolute dating method that involves counting the
annual rings visible in the cross-section of a tree is called:
Variants of elements that differ based on the number of
neutrons in the atom’s nucleus are called:
With a half-life of 5,730 years, 14C dating is useful for
dating carbonbearing objects as far back as:
Which dating method would be most appropriate for establishing the age of a volcanic ash layer from an early hominid site in eastern Africa?
Paleomagnetic dating relies on:
the periodic reversal of the earth’s magnetic poles.
Based on the molecular clock, it is estimated that the
hominid lineage diverged from that of the chimpanzee
The group of archaic mammals that lived during the Paleocene epoch and are likely very closely related to the earliest primates are:
The calcaneus (heel bone) of Eosimias suggests that it may
be a very primitive:
The earliest known South American primate is a
26-million-year-old monkey from Bolivia called:
Sivapithecus is widely recognized as an ancestral member
of which ape lineage?
A fossil primate with legs and arms of about equal length would most likely have gotten around using which form of locomotion?
The very large baboonlike monkey (up to 80 kg or 176 lbs)
that lived during the African Plio-Pleistocene was:
The most likely contender for the common ancestor of all
later catarrhines is:
The fossil nicknamed “Lucy” is a member of which species?
At which site would you be most likely to find fossil
remains of Australopithecus africanus?
Sterkfontein, South Africa
The only early hominid that lacks the thick enamel coating
on its teeth typical of other hominids is:
Fossils attributed to Australopithecus garhi were found at the Bouri site, in Ethiopia, along with:
Which of the following species is a good candidate for
being directly ancestral to Australopithecus afarensis?
Eugène Dubois found fossils of this species in Southeast Asia:
Modern human traits including increasing brain size and
dependence on material culture first show up in:
Homo erectus fossils date to:
Classic Homo erectus cranial features include all of the
Relative to Oldowan tools, Acheulean stone tools:
According to the text, the first hominid to migrate out of
The Daka Member, Ethiopia is a prime example of:
