Recent studies have refined and expanded earlier estimates of body and brain size variation. Researchers said body and brain size were two essential biological traits of the adaptive strategy of species. Researchers determined what temperature, precipitation and climate conditions the fossils might have been subjected to during their time when they were alive. The researchers identified temperature as a major predictor of body size variation in Homo Sapiens in the last one million years. Watch this video from Bright Side about pushing the limits of the human body in this true plane crash survival story of Juliane Koepcke: While humans have been able to do the unthinkable and survive despite the odds, don’t intentionally put yourself in harm’s way to know your human limitations. Each event in a story has a purpose, which might be to show. Stories often have a clear beginning, middle and end, which can also be called the introduction, body and conclusion, respectively. Plot is an element of literature that explains what happens in a story. The study, published in the journal Nature, stated that various hypotheses indicate the role of environmental, demographic, social, dietary, and technological factors behind human evolution. Parts of a Story: Introduction, Body & Conclusion. Researchers from Cambridge University and Tübingen University in Germany have studied data from 300 human fossils of the Homo genus and combined it with climate models to identify its role in human evolution. paper to create a diagram showing their ideas about how body systems rely on all. New research indicates climate had a role to play. Students learn how the human body is organized into systems of multiple.
