    • Despite decades of research, the field of language evolution lacks a cohesive integrative account, capable of explicating possible linguistic evolution throughout the development of modern humans. We review archaeological findings in search of a timeline during which features of the modern human articulatory morphology emerged. Rudimentary systems of speech may have driven selection for a vocal tract “optimal” for speech in early humans. However, a range of other factors have also enacted substantial morphological changes to the would-be speech articulators. The incorporation of processed and (ultimately) cooked food in the Homo lineage likely facilitated significant reduction of mandible and masticatory muscles, decreased the time spent masticating, and may have been maintainable in the lineage because food processing had already been outsourced to the hands and rudimentary stone tools (reducing selection pressure for robust jaws). The articulatory anatomy of early human ancestors is limited with regard to human speech sounds, but theoretically allows for a greater range of sounds than are observed in nature. We suggest that with decreased pressure to maintain anatomical elements required for mastication of foods that are mechanically challenging to eat, the would-be articulatory complex of human ancestors may have become pre-adapted for the development toward fully modern human speech.

    • Life experiences influence our research and motivate us to ask scientific questions and shape research goals. Here, Trends in Molecular Medicine authors share their journey in science. Their portraits highlight the diversity of scientists and that there is no standard career in science. We hope that these inspiring stories will help to build bridges of understanding between science and society, and motivate others to join the melting pot of scientific disciplines united in Trends in Molecular Medicine.
