Many people are overwhelmed by the fast-paced evolution
of mass communication in a world increasingly shaped by the
internet and artificial intelligence (AI). Yet ideas have
not always circulated across the globe at lightning
speed.
Looking into deep time allows us to view our
current mode of existence from a broader perspective and to
discern patterns of change that may offer insights into our
species’ possible trajectories in the future. We can begin
by trying to identify the conditions under which humans
developed complex symbolic communication, which is
considered unique in the animal kingdom. Today, we have
succeeded in transposing incredibly complex digital
languages, beyond the grasp of the human mind, into
computerized systems capable of processing, storing, and
sharing all kinds of information with the push of a button
or a click of a mouse.
Human language is at the root
of this system. While hardly perceptible in the
archeological record, hominin physiognomy assessed from the
fossil record allows us to observe that the capacity to
vocalize across a significant range dates back to a very
early time period. Physical features linked to resonance
complexity and articular precision, like the low positioning
of the larynx, an enlarged pharyngeal cavity, and a flexible
tongue housed in an ample palate, were already part of the
human anatomy by the time Homo erectus emerged in
Africa nearly 2 million years ago.
Somatic
harmonization, necessary for speech production, is ensured
by the tiny and crucial hyoid bone, a floating anchor for
the muscles controlling the tongue, throat, and voice box as
they work together to regulate sounds emitted during speech.
Paleoanthropologists studying the position, geometry, and
internal structure of Neanderthal hyoids discovered in
archeological sites found them to be nearly identical to
those of anatomically modern humans, suggesting that they
were already capable of emitting a similarly sophisticated
range of sounds. Evidence from Spain also reveals that
modern hyoid morphology was present by at least 530,000
years ago, indicating that it could be a derived
characteristic shared by modern humans and pre-Neandertals,
which they inherited from their last common
ancestor.

The ability to emit a wide range of
vocalizations characteristic of modern human language did
not appear abruptly, but rather, was favored over millennia
by interrelated adaptive elections taking place under the
evolutionary orchestration of both natural selection
and techno selection. As early as around 7 million
years ago, some early primates displayed several
craniofacial modifications believed to have evolved, at
least in part, to accommodate bipedal locomotion. These
included features such as reduced prognathism, more gracile
jawbones with smaller teeth, and a restructured skull base,
all of which subsequently facilitated the anatomical tweaks
necessary to increase the human capacity to pronounce a wide
range of sounds.
By the time hominins began
systematically making stone tools some 2.6 million years
ago, a series of changes in the archeological record
reflected the significance of this adaptive strategy. Around
1.75 million years ago in Africa, these (Oldowan)
assemblages were progressively replaced by Acheulian
industries comprising tools with wider technological and
morphological variability, including skillfully manufactured
and (esthetically pleasing) premeditated forms, like spheres
and symmetrical pointed tools called handaxes, which
required high degrees of dexterity to make.
Observing
synapses activated during experimental tool replication has
shown that the cognitive processes involved in passing on
the skills necessary to make such tools are linked to those
activated by language. Furthermore, evidence from ancient
DNA analysis suggests that regulatory genetic variants
favoring language-producing abilities underwent long-term
evolutionary selection in hominin populations, with some of
these features predating the divergence of modern humans and
Neanderthals.
Fully embracing the advantages offered
by their newfound technological proficiency, Acheulian
hominins benefited from access to the choicest morsels of
meat and viscera to feed their developing brains. They
experienced unprecedented demographic expansion and
assembled into more complex group settings sheltering
numerous individuals. Eventually wielding fire, Acheulian
populations spread into new lands within and beyond Africa,
utilizing their rapidly developing technologies to confront
diverse environmental and social challenges.
Some
archeologists have described this process as a biocultural
feedback loop, in which unprecedented cerebral growth
(supported by higher protein intake) was linked to
toolmaking. This process was catalyzed by increasing social
complexity, reinforced by the development of culture, and
favored the selection of symbolic communication.
Language—the preponderant expression of symbolic
transmission—initially developed as a survival-related
response to effectively transmit technological competence,
and ultimately became a means to express multifaceted
cultural norms developed to promote social
proficiency.
There is no doubt that culture evolves;
that it was/is transmitted socially through learning
processes that have been intricately developed over time and
now extend well past adolescence and, in some cases, beyond
the optimal reproductive age for women. Culture is
inherently cumulative: it is an aggregate of past human
experiences, errors, discoveries, adaptations, and
rectifications to deduce scientific and philosophical
insights about the universe—and our place in it. Symbolic
communication, expressed as language and writing, and later
also as art and music, reinforces cumulative culture by
allowing us to express, preserve, and share knowledge beyond
time constraints.
The story of technological evolution
following the emergence of the Acheulian reveals two major
forces that still operate today: acceleration and
complexification. By the end of the Acheulian and into the
Middle Paleolithic period and beyond, technological and
(linked) social achievements accumulated exponentially,
widening the baseline upon which hugely transformative
accomplishments emerged. At the same time, populations
multiplied, creating interrelational networks that favored
reproductive, material, and cultural exchanges.
I have
proposed defining this phenomenon as a fractalization
process, insofar as each branch replicates the underlying
evolutionary patterns, overcoming the constraints of its
ancestral source while retaining the full spectrum of human
cognitive expression. In this model (that is comparable to
biological natural selection), small variations or
adjustments can lead to exponentially magnified outcomes
through recursive and effectively infinite cycles of
reproduction.
By the time our own species came on the
scene more than 200,000 years ago, culture had flourished
into symbolic material expressions, inexorably linked to the
technological and social realities of past human lives.
Fire, for example, provided ample fodder for experimenting
with the power of transforming existing materials, enabling
new capacities during the Neolithic and Metal Ages, with
successive discoveries, such as pottery and, eventually,
glass and metallurgy, transmuting and enabling new societal
paradigms.
Following the shift from hunter-gatherer to
production-based lifeways, technological complexity split
individual role-playing into distinct occupations,
sharpening perceptions about (imagined) interpersonal
“value” within social settings. As populations swelled
and collective living arrangements expanded, these systems
became structured around complex symbolic interactions,
material cultures, territorial identities, and hierarchies
constructed to sustain group cohesion. Importantly, social
organization came to rely upon artificially constructed
(symbolic) notions that led regionally assembled groups to
contrast their ideas of communal belonging (identity) with
those existing in neighboring territories. As competition
for land and resources increased, these contrasting symbolic
realities became a justification for (sometimes violent)
interpopulation conflicts.
Communication networks grew
increasingly complex alongside expanding production and
territorial markets, accelerating the spread of cultural and
material exchanges. Protohistoric societies developed early
writing systems based on symbolic signs used as mnemonic
strategies to represent ideas and objects. Emerging
independently in regions such as Mesopotamia, Egypt, Central
America, and China, these systems gradually evolved from
pictorial symbols into stylized phonetic and logographic
writing largely detached from their original visual
meanings.
Throughout human experience, learning has
been central to survival, with scientific and behavioral
complexification acting as a driving force to develop
sophisticated new ways to educate, demonstrate, and train
each successive generation to become effective agents of our
seemingly unstoppable technological proficiency. Presently,
ideas move instantaneously across space and time through
global communication networks. Digital platforms make
information accessible worldwide, shrinking distances and
connecting populations, while promoting mass media and
consumer culture. Often shaped by corporate interests that
influence production, consumption, and resource distribution
in a world driven by digital images and symbolic messaging,
global connectivity has become the force shaping human
thought and social organization.
Uniformity is
increasingly becoming a defining characteristic of human
life shaped by digital communication. Despite the
technological sophistication of the systems that mediate and
transmit human thought, we are adopting simpler forms of
communication, homogenizing language, and gradually adapting
our patterns of thinking to fit the digital platforms used
to express them. The next stage of human evolution involving
the merging of human intelligence with AI may already be
here. As we become increasingly dependent on computerized
tools to function within contemporary social environments,
the ability to communicate effectively through digital means
is emerging as a fundamental requirement.
At the end
of the 1980s, screenwriter Maurice Hurley and the creators
of Star Trek showed remarkable foresight in creating
the Borg: fictional cybernetic organisms linked through a
single collective consciousness in which thoughts and
actions are shared and controlled by a powerful centralized
computer system. In this dystopian vision of the future, the
Borg’s main purpose is to assimilate other species in
pursuit of greater knowledge, efficiency, and power. Once
assimilated, subjects lose their individuality and become
linked to the Collective (or hive mind).
As
humanity moves toward a predicted state of post-humanism
(human-machine hybridization) and the boundaries between
human cognition and machine intelligence become increasingly
blurred, it is worth asking whether this vision already
mirrors some aspects of our own interconnected and
technology-mediated world.
