Neanderthals had a long, low skull (compared to the more globular skull of modern humans) with a prominent brow ridge above their eyes. Pictured, a skull at a Neanderthal exhibition at the Musee de l'Homme in Paris
Professor Guido Barbujani, an evolutionary anthropologist at the University of Ferrera in Italy, told MailOnline: 'Genitalia are not preserved in fossils, and there is no way to figure out what they looked like in Neanderthals.
Neanderthals had large noses, strong double-arched brow ridge and relatively short and stocky bodies. The species ranged widely in Eurasia (Europe and Asia), from Portugal and Wales in the west across to the Altai Mountains of Siberia in the east
Wild animal meat accounts for up to 80% of the animal protein consumed by populations in some rural regions of West and Central Africa, which makes it key both to the local economy as well as to food security, said the WWF report.
'Neanderthals were probably able to speak as we can infer from the morphology of some bones and from inferences we can do of their brain,' Alessia Nava, anthropologist at the University of Rome, told MailOnline.
A study published in 2021 in the ICES Journal of Marine Science by researchers in Canada and Germany showed, for example, that cod catches in Eastern Canada reached a peak in 1968, at 810,000 tons, but fell to 10,559 tons in 2019 following a collapse in fishing stocks.
For example, research published in 2011 as part of The Economics of Ecosystems and Biodiversity initiative suggested that loss of small mammal species contributes to the spread of diseases such as hantaviruses.
Research published in 2020 by the Proceedings of the Royal Society B journal showed that five out of seven crops studied in the United States already lacked enough pollinators, such as bees, to secure full development.
Globally, destruction of natural areas coupled with climate change enabled 4.3 million square km of land (1.7 million square miles), an area larger than India, to turn dry between 1990 and 2020, according to figures released in 2024 by the U.N.
It is estimated, however, that great whale numbers have declined between 66% and 90% since commercial whaling began about 1,000 years ago, which means that they are making less of a contribution to keeping oceans plentiful.
In the case of the Amazon, a 2019 paper published in the Biotropica journal by Brazilian researchers found that tapirs distribute seeds over long distances and help speed the recovery of disturbed forests.
Humans also consume up to 2,500 freshwater fish species, research published in 2023 by the WIRES Water journal said, and a 2011 report in the Fish and Fisheries journal estimated that marine fisheries provide more than 200 million full-time jobs globally.
Biodiversity is essential to keeping ecosystems healthy foods to lose weight and able to provide humanity with what are called ecosystem services such as food, crop pollination, soil protection, cooling, fresh water and even leisure.
Predators, meanwhile, contribute to keeping herbivore populations under control, limiting the risk of soil erosion from overgrazing, a 2014 report in the Science journal said. In the oceans, sperm whales mix water and move nutrients through ocean layers with their large bodies, nourishing ecosystems and providing fishing grounds.
In grassland ecosystems, hoofed terrestrial herbivores compact the bare ground and soil, altering landscapes and promoting higher biodiversity, a 2024 assessment of research published in the Nature Ecology & Evolution journal showed.
From the large whales that mix ocean waters and make them more able to sustain life to tapirs that help the Amazon forest grow and provide rainwater to South America, the planet's biodiversity is deeply connected to humanity's well-being.
A 2018 study published by the Philosophical Transactions of the Royal Society B concluded that many human populations are undergoing an "extinction of experience," as destruction of habitats and concentration in urban areas makes interactions with wildlife more rare.
