Professor Peter Wilf at Pennsylvania State University is using the latest machine learning technology to identify ancient leaves. A computer program he developed can scan leaves and categorise them into families, leading to a better understanding of where the more than 200,000 species of flowering plant that grown on earth today have come from.
