Human evolution is a subject that has been explored for some time now. Since even before the time of the renowned naturalist Charles Darwin, the links between animals (and indeed plants) and their ancestors were being made, and their physical developments inferred, charted, and commented upon.<\/p>\n
Along with \u2013 and inextricably linked to \u2013 the evolution of a species is the habitat in which that species prevails. This, again, is not new knowledge; should an environment, for instance, become inhospitable \u2013 whether through climate change, natural events such as volcanoes and earthquakes, or a decline in prey\/overabundance of predators \u2013 then the species in question must relocate or risk extinction.<\/p>\n
This presents an interesting way of exploring the evolution of hominins \u2013 our human ancestors. As Professor Sally Reynolds, Principal Academic in Hominin Palaeoecology and Head of the Institute for Studies of Landscape and Human Evolution at Bournemouth University<\/a>\u2019s Department Archaeology and Anthropology, told The Innovation Platform<\/em><\/a>\u2019s International Editor, Clifford Holt: \u201cOne of the most important elements of our ancestors\u2019 habitats is their choice of landscape. This dictates access to specific food resources, prey availability, and presence of predators \u2013 many of whom are still extant species and whose behaviour is well studied.<\/p>\n \u201cWere they living in grassland savannah? Or deep forest? Did our earlier ancestors originate in deep forest habitats and move onto open grassland plains, as some of the earliest scholars like Raymond Dart suggested?\u201d<\/p>\n Reynolds and her team employ various tools and methods to better understand this relationship between hominins and their landscape. These include:<\/p>\n With regards to remote sensing, satellite imagery is freely available, and Reynolds and her team are thus able to take a time series approach to look at how a single landscape (like the Okavango Delta, for instance) changes in terms of vegetation over a single year, or even several decades. She explained: \u201cWe can use an approach of analogies, for example comparing aspects of what we see in the past record of Olduvai Gorge appear similar to that of the present day Okavago Delta. We can use this approach to create a framework for understanding some of the key features preserved at Olduvai Gorge.\u201d<\/p>\n Other GIS based approaches, such as Least Cost Path analysis, are also used to help develop a better understanding of the key routes and access to regions of interest to human evolution, Reynolds added. \u201cWe also make great use of SfM (Structure from Motion) photogrammetry techniques to capture and digitise rare and fragile exposed human footprints which will start to erode as soon as they are exposed to air. Work like that taking place at White Sands National Park, New Mexico, USA, means that fragile prints would be lost if we could not digitally record and preserve them.\u201d<\/p>\nModern tools for historical explorations<\/h3>\n
