“…This possibility was used by Dennell and Roebroeks () to argue that a pre‐human species could have been the first hominin to emerge from Africa, rather than H. erectus , and that it was represented by a long‐lived descendant lineage, surviving in a remote isolation on the island of Flores for over 1 million years. These arguments will continue with the addition of H. luzonensis to the fossil record (Détroit et al , ; Tocheri, ).…”

“…(e) H. floresiensis may be a descendant of H. erectus that dwarfed on the island of Flores, or alternatively it evolved from an even deeper, pre‐ erectus divergence. Here we remain agnostic, although the recently announced H. luzonensis (Détroit et al , ) may add to this debate. Evidence indicates that there was gene flow (red lines) at various times throughout the last 1 million years, although the rate and frequency of this is still being established.…”

This paper reviews some of the main advances in our understanding of human evolution over the last 1 million years, presenting a holistic overview of a field defined by interdisciplinary approaches to studying the origins of our species. We begin by briefly summarizing the climatic context across the Old World for the last 1 million years before directly addressing the fossil and archaeological records. The main themes in this work explore (i) recent discoveries in the fossil record over the last 15 years, such as Homo naledi and Homo floresiensis; (ii) the implications of palaeogenetics for understanding the evolutionary history of, and relationships between, Neanderthals, Denisovans and Homo sapiens; (iii) the interplay between physiology and metabolic demand, landscape use, and behavioural adaptations in the evolution of morphological and behavioural innovation; and (iv) recent advances in archaeological understanding for the behavioural record, in particular that of the Neanderthals. This paper seeks to provide a broad‐scale, holistic perspective of our current understanding of human evolution for the last 1 Ma, providing a reference point for researchers that can be built upon as new discoveries continue to develop the landscapes of human evolution. © 2019 The Authors.

“…Finally yet importantly, I would like to note that almost each new genome sequence from an ancient hominin led to massive and unexpected revelations. In parallel, the past decade was full of new and exciting fossil discoveries, including Homo naledi in South Africa (Dirks et al, ), Homo florensis in Indonesia (Brown et al, ), and Homo luzonensis in the Philippines (Détroit et al, ). Moreover, the fossil record in East Asia—especially in China—has been scrutinized with a new lens based on the recent genomic evidence (Bae, Douka, & Petraglia, ).…”

“…(See "A Potential Defensive Resource: Integration Analysis" section for a workaround.) And in many of the fields accustomed to high-p/n data sets, wide variation of subgroup sample sizes has become a commonplace, as in recent studies of species of Homo, partially bgPCA-driven, by, among others, Chen et al (2019), Détroit et al (2019), and Mounier and Lahr (2019). Yet variability of subgroup size when the p/n ratio is high is the requisite for this paper's second main pathology, the automatic alignment of the first one or two bgPCA axes with contrasts of the grand mean against the smallest one or two subgroups only.…”

Pathologies of Between-Groups Principal Components Analysis in Geometric Morphometrics

Good empirical applications of geometric morphometrics (GMM) typically involve several times more variables than specimens, a situation the statistician refers to as "high p/n," where p is the count of variables and n the count of specimens. This note calls your attention to two predictable catastrophic failures of one particular multivariate statistical technique, between-groups principal components analysis (bgPCA), in this high-p/n setting. The more obvious pathology is this: when applied to the patternless (null) model of p identically distributed Gaussians over groups of the same size, both bgPCA and its algebraic equivalent, partial least squares (PLS) analysis against group, necessarily generate the appearance of huge equilateral group separations that are fictitious (absent from the statistical model). When specimen counts by group vary greatly or when any group includes fewer than about ten specimens, an even worse failure of the technique obtains: the smaller the group, the more likely a bgPCA is to fictitiously identify that group as the end-member of one of its derived axes. For these two reasons, when used in GMM and other high-p/n settings the bgPCA method very often leads to invalid or insecure biological inferences. This paper demonstrates and quantifies these and other pathological outcomes both for patternless models and for models with one or two valid factors, then offers suggestions for how GMM practitioners should protect themselves against the consequences for inference of these lamentably predictable misrepresentations. The bgPCA method should never be used unskeptically-it is always untrustworthy, never authoritative-and whenever it appears in partial support of any biological inference it must be accompanied by a wide range of diagnostic plots and other challenges, many of which are presented here for the first time.Keywords Between-group principal components analysis · Ratio of variables to cases · High-p/n data sets · Discriminant function analysis in high dimensions · Factor analysis and discrimination · The Marchenko-Pastur theorem · Geometric morphometrics · Predictable mistakes in biometric data analysis · Effects of varying group size · Alternatives to canonical variates analysis
