Interview with paleoanthropologist Katerina Harvati, who studies Neanderthal evolution and modern human origins at the Eberhard Karls University of Tübingen.

How assumptions shape the paleosciences.

Science is a very special form of storytelling, one in which the stories told have to be testable against empirical observation. But the world is a complicated place; and, to provide a coherent account of it, scientists often find themselves obliged to join up their observable dots using untestable or as-yet-untested lines. This is a necessary part of constructing many valuable and predictive scientific scenarios; and it is perfectly good procedure as long as the assumptions involved are fully compatible with what is known and testable. But it also means that, in formulating their ideas about how the world works (or worked), scientists must remain keenly aware not only of what is and is not assumption in those complex ideas, but of how untested elements may color their beliefs. The contributions to this volume cover many interesting examples of how assumptions have affected ideas in diverse areas of the paleosciences, both practical and theoretical, and they serve together as a salutary reminder that vigilance and a willingness to rethink are always in order.

Measure, Then Show: Grasping Human Evolution Through an Inquiry-Based, Data-driven Hominin Skulls Lab.

Incomprehension and denial of the theory of evolution among high school students has been observed to also occur when teachers are not equipped to deliver a compelling case also for human evolution based on fossil evidence. This paper assesses the outcomes of a novel inquiry-based paleoanthropology lab teaching human evolution to high-school students. The inquiry-based Be a Paleoanthropologist for a Day lab placed a dozen hominin skulls into the hands of high-school students. Upon measuring three variables of human evolution, students explain what they have observed and discuss findings. In the 2013/14 school year, 11 biology classes in 7 schools in the Greater New Orleans area participated in this lab. The interviewed teacher cohort unanimously agreed that the lab featuring hominin skull replicas and stimulating student inquiry was a pedagogically excellent method of delivering the subject of human evolution. First, the lab's learning path of transforming facts to data, information to knowledge, and knowledge to acceptance empowered students to themselves execute part of the science that underpins our understanding of deep time hominin evolution. Second, although challenging, the hands-on format of the lab was accessible to high-school students, most of whom were readily able to engage the lab's scientific process. Third, the lab's exciting and compelling pedagogy unlocked higher order thinking skills, effectively activating the cognitive, psychomotor and affected learning domains as defined in Bloom's taxonomy. Lastly, the lab afforded students a formative experience with a high degree of retention and epistemic depth. Further study is warranted to gauge the degree of these effects.

The palaeontological exhibition: a venue for dialogue.

Understanding the dialogue between museums and their visitors enables museums to subsist, undergo transformations and become consolidated as socially valued cultural venues. The Museo de La Plata (Argentina) was created in the late nineteenth century as a natural history museum, and this study shows that currently the museum is valued socially as a venue for family leisure and education, at which people make sense to the objects exhibited through characteristics conferred upon them by both the institution and the visitor. Nevertheless, such dialogue is somehow affected by the museographic proposal and the public interpretation of the institutional narrative, which could be analysed within the frame of contextual learning. As a consequence, the evolutionary idea that the museum aims to communicate is distorted by the public. This article highlights the importance of considering the visitors' interpretations when planning museum exhibitions, a perspective that has been rather absent in the Argentinian museums.

Biagio Bartalini's "Catalogo dei corpi marini fossili che se trovano intorno a Siena" (1776).

In 1776, the Sienese botanist Biagio Bartalini (1750-1822) published a catalogue of wild plants growing around Siena, adding an appendix on fossils found in the same area, that is the first monograph on Sienese fossils and one of the first works of its kind in Italy. This paper provides tentative identifications of the species and an analysis of the value and meaning of Bartalini's work. The catalogue reports 72 species, each denoted by a list of names applied to analogous living taxa. Identification of single entities is extremely problematical because it can only be attempted through analysis of the literature, since the original material cannot be traced. The most interesting report is the first record of a Euro-Mediterranean Pliocene species of Sthenorytis (Gastropoda, Epitoniidae). Though important, the catalogue is incomplete, with oversights and mistakes, suggesting little familiarity with the subject. Shortcomings include some inconsistencies in the species sequence, the report of giant clams and the absence of molluscs ubiquitous in the Sienese Pliocene and sharks. Nor is it true that it is the first Italian palaeontological work in which binomial nomenclature was used, as sometimes claimed.

[The diffusion of the human evolution in Spain and the JAE (1907-1939)]. / La evolución humana y su difusión en España en el marco de la JAE (1907-1939).

During the first decades of the 20th century important findings of hominids fossil remains were made, enlarging the knowledge on Human Evolution. This period runs parallel to the activity of the Junta para Ampliación de Estudios e Investigaciones Científicas (JAE), an institution that helped to spread the new paleontological facts in Spain by providing funds for further studies and research, by the foundation of the Comisión de Investigaciones Paleontológicas y Prehistóricas (CIPP) and the promotion of publications on Human Paleontology.
