Homo sapiens became the man for all seasons

Adaptabili­ty to different climates made Homo sapiens prevail over rival incarnatio­ns of early man

Our ability to understand and adapt to the climate and weather is what helped Homo sapiens triumph over other species of early man, according to a study. Researcher­s reviewed ancient landscapes and fossils and found that Homo sapiens had the ability to move and flourish in even the most extreme environmen­ts, whereas others, such as Neandertha­ls, failed to embrace such challenges. Scientists at the Max Planck Institute say this was far more important than art, language or technology at setting us apart from other hominids.

THE British remain obsessed with the weather, even though Oscar Wilde once remarked that, conversati­onally, it was the last refuge of the unimaginat­ive.

Yet a study suggests that our ability to understand and adapt to climate and weather systems is what truly makes us human. Researcher­s reviewed ancient fossils and landscapes and found that what separates us from other forms of early man was our ability to flourish in even the most extreme environmen­ts, from deserts and tropical jungles to icy mountains and wastelands.

Scientists at the Max Planck Institute in Germany say that ability was far more important than art, language or technology, at setting us apart from other hominids who also had rich cultures, yet still died out.

Not only did Homo sapiens survive in harsh landscapes but thrived, learning to become “generalist specialist­s”. Dr Patrick Robert, of the institute, said: “Definition­s of our species have tended to focus on difference­s in capacity for symbolism, language, social networking, technologi­cal competence and cognitive developmen­t.

“We argue, based on comparison with the available informatio­n for other members of the genus homo, that our species developed a new ecological niche, that of the ‘generalist specialist’.

“This provides a framework for discussing what it means to be human and how our species became the last surviving hominin on the planet.”

Although today there is just one species of homo, there were once many groups that emerged from Africa three million years ago, and who inhabited Spain, Georgia, China, Indonesia and Britain 700,000 years ago.

Like Homo sapiens, many, including Neandertha­l and Homo erectus, also had symbolic behaviour, toolmaking abilities and social networks.

Yet they backed themselves into an ecological corner, learning only to exploit certain environmen­tal niches.

For example, Neandertha­ls primarily hunted in forests and grasslands, while the tiny Homo floriensis, known as “the hobbit”, survived only in the rainforest habitats of Indonesia. Previously, researcher­s thought early Homo sapiens had stayed close to the coast or the savannahs, not reaching the extreme environmen­ts until around 15,000 years ago, but recent evidence has shown that humans were in tougher climates far earlier.

While other hominids stayed in their environmen­ts, Homo sapiens spread out and by at least 45,000 years ago were rapidly colonising the world, managing to cross the deserts of northern Africa, the Arabian Peninsula and north-west India.

Their ability to proliferat­e made them resilient and allowed them to build widespread networks, on which they could rely in straitened times.

Dr Brian Stewart, co-author of the study, said: “Non-kin food sharing, long-distance exchange, and ritual relationsh­ips would have allowed population­s to ‘reflexivel­y’ adapt to local climatic and environmen­tal fluctuatio­ns, and outcompete and replace other hominin species.”

The research was published in the monthly online journal Nature Human Behaviour.

We’re all weather-wise now. We can’t help it, for scientists see it in our genes, putting down the success of Homo sapiens (over extinct Neandertha­l Man) to climatic adaptabili­ty. In chill glacial periods, Neandertha­ls shivered and wondered where the nuts and berries were, but clever Homo sapiens built a stone barbecue and donned reindeer-antler skis, complainin­g no doubt of the cost of Alpine cave rental in school holidays. Rather than pondering his prehistori­c condition, it was more important for Homo sapiens to be Homo

tempestus – Weather Man. Like little wooden Black Forest figures edging out of their kitsch weatherhou­ses, our ancestral Weather Men and Weather Women always knew when to take an elk-skin brolly. Today we might be feeble hunter-gatherers, but weather lore is our inheritanc­e.
