Lydia Pyne “Seven Skeletons: The Evolution of the
World’s Most Famous Human Fossils,” Viking, 2016, 243 pp.
Over the last
century, the search for human ancestors has spanned four continents and
resulted in the discovery of hundreds of fossils. While most of these
discoveries live quietly in museum collections, there are a few that have
become world-renowned celebrity personas. In Seven Skeletons, historian of science Lydia Pyne describes a
cultural history for seven selected celebrity fossils—from their discovery to
their afterlife in museums.
These seven include the three-foot tall “hobbit”
from Flores, the Neanderthal of La Chapelle, the Taung Child, the Piltdown Man
hoax, Peking Man, Australopithecus Sediba, and Lucy. These seven tell us about our evolutionary
ancestry covering millions of years. Lucy, so far the oldest of these seven, roamed
the earth 3.5 million years ago.
Pg. 14:
The Neanderthal of La Chaplelle fossil described in this book, was
discovered in 1908 and was the first complete Neanderthal skeleton. Earlier, a Neanderthal skull had been found
in the Neander valley in 1856. (See my April 12, 2016 review of The Strange Case of the Rickety Cossack).
Pg. 34: Today Archaeologists consider Neanderthals to
have been just as smart, just as technologically apt, just as culturally
nuanced as Homo sapiens. Despite this
shift in interpretation, the Neanderthal as a hapless caveman is so firmly
entrenched in our cultural consciousness that it is exceptionally difficult to
dislodge it. Why they did not survive
along with us is still unsolved—climate change is the probable cause of their
extinction thirty thousand years ago, they had adapted to the colder, glacial
age..
Pg. 53: Piltdown Man (a hoax). Piltdown man was allegedly discovered by
Charles Dawson in 1912. When assembled
together the fossil appeared to have an apelike jaw and humanlike skull, suggesting
the fossil could be the perfect missing link between apes and humans. It wasn’t until 1953 when the Piltdown
materials were found to be a hoax. It
was a fossil forgery of the first degree, comprising real but very recently old
human crania, orangutan bones, and chimpanzee teeth all masquerading as a
fossil much older than it was. The
reason the hoax was so successful, other than the absence of accurate dating mechanisms,
was that the hoax fit the world-view of the archeologists.
Pg. 90: Dominant evolutionary theory of the early
twentieth century believed human fossil ancestory ought to be apelike,
big-brained ancestors from Southeast Asia or Europe. All establishment scientists were all firm
proponents of Piltdown Man as an ancestor; Piltdown’s anatomy supported the
current trends in evolutionary thinking, and it was not until 1953 that the
Piltdown fossil was found to have been a hoax.
Pg. 103: With the discrediting of the Piltdown Man in
1953, intellectual space for accepting the Taung fossil as a hominin ancestor
opened up.
Pg. 119: Forty boxes containing skulls, jaws, teeth,
and other bones from fossil collections at the archaeological site of
Zhoukoudian in China during the 1920s and 1930s became known as Peking
Man. Today Peking Man is taxonomically
assigned to Homo erectus—an extinct
Pleistocene species in humans’ evolutionary tree roughly 750,000 years
old. Extensive analysis reveals that the
species had sophisticated stone tools and offered the first systematic use of
controlled fire outside of our own species, Homo
sapiens.
Pg. 153: Lucy, discovered in Ethiopia in 1974, was
assigned to the extinct hominin species Australopithecus
afarensis—a species that lived 3.25 million years ago.
Pg. 187: The Hobbit was discovered in 2003 on the
island of Flores, Indonesia. This small
three-foot tall adult hominin was named Homo
floresiensis and christened ‘Flo’, she is best known to the rest of the
world as the real-life hominin hobbit.
This discovery of Flo and eight other small hominins was a game changer
in human evolution studies. Finding a
hominin so small, with such a small brain, so relatively late in the geologic
record, and in Southeast Asia shook up how scientists thought about human
evolution. The species so far discovered
lived from 100,000 to 18,000 years ago. (P. 195).
Pg. 200: Although Flo’s brain is small, evidence
indicates she and others in her species were able to make and use stone tools
and had a keen mastery of fire. (Flo’s
brain size is measured at 400-426 cubic centimeters in volume, compared with
approximately 1,300 cubic centimeters for modern Homo sapiens.)
Pg. 213: Sediba discovered in 2008. This species has still does not have an
accepted classification as belonging to the Homo or Australopithecus species.
Pg. 216: The year 2010 was a great one for studies in
human evolution: two major new hominin discoveries entered the scientific
record. These new fossils were both
members of the genus Australopithecus,
around two million years old.
