Five ancient human species that lived alongside modern humans revealed: New insights into our prehistoric cousins
human evolution
, scientific research confirms that Homo sapiens—modern humans—were not alone for much of their early history. Between approximately 300,000 and 40,000 years ago, several closely related
ancient human species
lived alongside us, interacted with us, and in some cases interbred with our ancestors. Far from being the solitary pinnacle of evolution,
Homo sapiens
shared the planet with a diverse cast of human relatives whose legacy lingers in our DNA and in our story.
The five ancient human cousins
Neanderthals (Homo neanderthalensis)
Perhaps the best-known and closest extinct relatives of modern humans, Neanderthals first appeared about 400,000 years ago. Unlike the outdated stereotype of brutish cavemen, they were highly intelligent, sporting brains on average larger than modern humans. Adapted to cold Eurasian climates, they had stocky bodies, large noses to warm inhaled air, and used sophisticated tools, clothing, and fire.
Genetic studies reveal that 1–2% of DNA in Europeans and Asians today originated from Neanderthals, influencing aspects such as immune system function. Their extinction roughly 40,000 years ago did not end their contribution to our genetic makeup.

Denisovans (Homo sp. Denisova)
Discovered only in 2008 from a tiny finger bone in Siberia's Denisova Cave, Denisovans remain one of the most mysterious human cousins. DNA sequencing shows they diverged from Neanderthals about 550,000 to 765,000 years ago and lived from roughly 300,000 to 25,000–30,000 years ago in parts of Asia. Genetic evidence indicates adaptations such as dark skin, eyes, and hair, with physical traits somewhat reminiscent of Neanderthals.
Remarkably, one genome from a bone fragment revealed a first-generation hybrid with a Neanderthal mother and a Denisovan father.
Fossil
and genetic evidence suggest they inhabited a wide ecological range—from Siberia's cold caves to Southeast Asia's tropical forests—illustrating a previously hidden human diversity.
Homo naledi
Found in South Africa in 2013, Homo naledi is an enigmatic species. With a small brain size of around 465–560 cm³, comparable to earlier ancestors like Australopithecus, yet living contemporaneously with Homo sapiens roughly 335,000 to 236,000 years ago, Homo naledi defies simple evolutionary assumptions. Standing about 1.44 meters tall, they had long fingers and an anatomy suggesting strong climbing ability. Their diet likely consisted of nuts, tubers, and other plant matter, pointing to a different ecological niche from early modern humans.
Though they left no known genetic trace in modern populations, their coexistence with Homo sapiens underscores the complex diversity of human morphology and behavior during the late Pleistocene.
Homo floresiensis
Nicknamed "Hobbits" due to their small stature, Homo floresiensis was discovered in 2003 on Indonesia's Flores island. These tiny humans stood only about 1.1 meters tall and had brains around 400 cm³ in size. Despite these archaic features, their use of stone tools and ability to hunt dwarf elephants point to a sophisticated species. They are believed to have descended from
Homo erectus
populations that underwent island dwarfism.
Homo floresiensis likely survived until around 60,000 to 38,000 years ago, potentially overlapping with Homo sapiens in Southeast Asia. Some anthropologists speculate their presence might have inspired local myths such as the Ebu Gogo—small forest-dwelling people from Flores folklore.
Live Events
Homo erectus
One of the longest-surviving human species, Homo erectus appeared about 1.9 million years ago and was the first human species known to leave Africa and colonize large areas of Europe and Asia. They showed significant evolutionary advances, including fully upright posture, use of fire, and persistence hunting—chasing prey until it collapsed from exhaustion.
Their brain size and body shape were more human-like than earlier hominins, and they are considered direct ancestors of later human species, including Homo heidelbergensis, which is thought to be a common ancestor of Neanderthals, Denisovans, and Homo sapiens. Fossil evidence suggests H. erectus survived in parts of Asia until about 140,000 years ago.
A shared evolutionary tapestry
These findings highlight that humans did not evolve in isolation but rather as part of a broad family of ancient human groups exhibiting rich biological and ecological diversity. Our direct ancestors interbred with some of these species, notably Neanderthals and Denisovans, weaving their genes into ours and inheriting traits that helped us adapt to new environments.

COVID-19 pandemic may have aged your brain, even if you weren't infected, finds UK study
According to the researchers, however, these changes could be 'partially reversible' but the most significant aspect highlighted in the study was how much simply living through the uncertainty and isolation of the pandemic affected brain health. Using brain scans from nearly 1,000 healthy adults from before and after the pandemic, researchers found signs of faster brain ageing, especially in older adults, men, and those from disadvantaged backgrounds. Of these samples, those who were infected with COVID-19 also showed some decline in thinking speed and flexibility. But overall, the pandemic's stress alone did shift brain structure in all individuals whose scans were reviewed. New Delhi: A new study from the University of Nottingham has found that just living through the COVID-19 pandemic may have aged people's brains faster, even if they never got infected with the virus itself. The peer-reviewed study was published on 22 July in the journal Nature Communications and is based on data from the UK Biobank Study. It's a powerful reminder that our environment matters for our brain's growth. Read more here. Also Read: A UK health study has collected a whopping 100,000 full-body scans, and Neanderthals had 'family recipes' Spiders originally came from the sea? Next, we might have evidence that spiders could have originally been sea creatures. At least that is what a new peer-reviewed study published in the journal Current Biology on 22 July suggests, after researchers closely examined a preserved fossil from half a billion years ago. The fossil is called Mollisonia symmetrica, and it has a nervous system very similar to that of modern-day arachnids like spiders and scorpions. Until now, scientists thought these creatures only evolved once their ancestors moved onto land 400 million years ago and have remained the same ever since. But this new study flips that theory on its head, quite literally. It cites evidence of the brain of the fossil Mollisonia, which shows a reversed organisation—a signature trait seen in today's arachnids. This arrangement may have given them faster reflexes, better control, and precision, which are all traits modern-day spiders use to hunt and weave webs. The fossil places Mollisonia as a close relative of modern arachnids, meaning these creatures might have started evolving in the ocean long before they crept onto land. Read more here. Scientists genome sequence 100-yr-old Spanish Flu virus A 100-year-old lung sample from Switzerland helped scientists decode the deadliest flu in human history. A new peer-reviewed study by researchers from the Universities of Basel and Zurich published in BMC Biology Journal on 1 July sequenced the genome of the 1918 'Spanish flu' virus. They used preserved tissue from a young patient who died during the pandemic's first wave in Switzerland. The Spanish flu that spread across Europe and Asia in the 1910s is said to have killed between 20-100 million people. By decoding the genome, scientists now have insights into how this flu had already adapted to humans early on. They found three key mutations in the genome—two which helped the virus evade the human immune system, and one which boosted its ability to infect human cells. What makes this study stand out is also how they conducted the study. In viral flus, the genetic information rests in the RNA, not the DNA. The RNA is very quick to degrade but these scientists developed a method to recover ancient viral RNA. This technique could open the door to learning more from historic outbreaks. Read more here. Arctic winter is melting, and researchers have noticed it A group of scientists led by Dr James Bradley from Queen Mary University, London, published a commentary in Nature Communications on 21 July talking about the 'shockingly warm' winter conditions in the Arctic. The team described how they had geared up for winter Arctic fieldwork in Svalbard, wearing layers of thermal clothing, only to find themselves drenched in rain, standing on bare grass, and working without even needing gloves in what is supposed to be the middle of winter in February 2025. Svalbard is a Norwegian archipelago located where the Arctic Ocean converges with the Atlantic Ocean. In the commentary, they raised alarms about melted snow pools, blooming vegetation, and rain replacing snow in the Arctic Circle during winters. Svalbard is heating up six to seven times faster than the global average, and the Arctic winter is no longer reliably frozen, said the team. These conditions not only disrupted their research but also raised safety concerns, like how to retreat from polar bears without their snowmobiles working. The team warns that winter warming in the Arctic is not a fluke but rather the new norm. The message sent by the commentary is clear: climate policy needs to catch up, and fast. Read more here.
