To study evolution, we need to study differences among lots of individuals. We need to know how and why these differences change through time. This need to measure lots of individuals means that the current practise of a person pointing and clicking on a computer screen to identify distinct parts is too slow. Computer programmes that provide a faster, more repeatable and less biased way of identifying and analysing such parts are now available, completing the toolkit needed to build big databases. By bringing together lessons from diverse scientific disciplines, we propose to use the same fossil specimens to collate records of an individual's journey through life and the environment it experienced every step of the way, both of which were changing from day-to-day, millions of years ago. While the fossil record of planktonic foraminifera provides the necessary timespan and abundance, new computer programmes and imaging technology complete the toolkit jigsaw to investigate for the first time if certain parts of an individual's journey through life are more influential than others in determining the eventual evolutionary destinations of its species. Our unique, direct link between organism and environment lets us study the dynamic journey through life in the static death of the fossil record. The fundamental limitation to the current ways we study how new species emerge is the lack of repeated samples through time to follow the genesis of novel lifeforms, and explicitly targeting this limitation using state-of-the-art approaches from multiple scientific disciplines means we will deliver a breakthrough in attempts to answer one of the most fundamental of all biological questions: how do differences among individuals make differences among species?
