odern molecular studies
mapping the genomes
of humans and other
animals have confirmed a theory
that was first suggested by Charles
Darwin in the mid-19th century—
that we share a common ancestor
with the great apes. Today, few
scientists would dispute that the
common chimpanzee (Pan
troglodytes) and the bonobo or
pygmy chimpanzee (Pan paniscus)
are our closest living relatives. The
study of these animals therefore
offers us a unique chance to learn
about ourselves and the origins of
our behavior. Yet for many years the
scientific community remained
convinced that humankind was
different from the rest of nature.
It was largely the work of British
primatologist Jane Goodall that
opened our eyes to the similarities
between chimps and man. In 1961,
in an excited communication
to her mentor, Louis Leakey,
Goodall announced an observation
that would shake the scientific
establishment: she had seen
a chimp using a tool. It was the
first time this behavior had
been documented and it would
challenge perceived ideas of what
it means to be human.

1758 Carl Linnaeus, the father
of taxonomy, dares to classify
humans within the rest of
nature, calling us Homo
sapiens (“wise man”).
1859 Charles Darwin’s
theory of evolution further

1963 Konrad Lorenz publishes
On Aggression, proposing
that warlike behavior in
humans is innate.
1967 Desmond Morris,
a British zoologist and
ethologist, publishes The
Naked Ape: A Zoologist’s
Study of the Human Animal,
a major study that describes
human behavior in the
context of the animal kingdom.
In reality, we are Pan narrans,

Humans and their
closest relatives,
chimpanzees, are both
primates. This shows
how primates have
evolved over the last
66 million years.
