Natal philopatry, the return of individuals to their natal area for reproduction, has advantages and disadvantages for animal populations. Natal philopatry may generate local genetic adaptation, but it may also increase the probability of inbreeding that can compromise persistence. Although natal philopatry is well documented in anadromous fishes, marine fish may also return to their birth site to spawn. How philopatry shapes wild fish populations is, however, unclear because it requires constructing multigenerational pedigrees that are currently lacking for marine fishes. Here we present the first multigenerational pedigree for a marine fish population by repeatedly genotyping all individuals in a population of the orange clownfish (Amphiprion percula) at Kimbe Island (Papua New Guinea) during a 10-y period. Based on 2927 individuals, our pedigree analysis revealed that longitudinal philopatry was recurrent over five generations. Progeny tended to settle close to their parents, wit...
Despite recent, compelling challenge, the evolution of Homo erectus is still commonly attributed to big game hunting and/or scavenging and family provisioning by men. Here we use a version of the ‘‘grand- mother’’ hypothesis to develop an alternative scenario, that climate- driven adjustments in female foraging and food sharing practices, possibly involving tubers, favored significant changes in ancestral life history, morphology, and ecology leading to the appearance, spread and persistence of H. erectus. Available paleoclimatic, environmental, fossil and archaeological data are consistent with this proposition; avenues for further critical research are readily identified. This argument has important implications for widely-held ideas about the recent evolution of long human lifespans, the prevalence of male philopatry among ancestral hominids, and the catalytic role of big game hunting and scavenging in early human evolution.
The Physiology of Fishes 5th Edition, 2021
Over half of the world’s living vertebrates are fishes (more than 85 orders, 536 families, 5000 living genera, 34,000 species, and counting; Nelson et al. 2016). Fishes arose and began to radiate almost 500 million years ago and now exhibit incomparable diversity (Figure 1.1) in morphology, physiology, ecology, and behaviour. To understand biotic diversity, we employ phylogenetic systematics. Phylogenies provide hypotheses of relationships among species to better understand character evolution within and between groups, visualized as phylogenetic trees or branching diagrams, and are the foundation for comparative studies, including comparative physiology. The purpose of this chapter is to present an overview of the current hypotheses of fish phylogeny as a framework for understanding the remarkable diversity of fishes. We concentrate on the arrangement of large, important clades (Figure 1.2) to illustrate broad patterns. Information presented mainly follows Nelson et al. (2016). Another recent overview is that of Hastings et al. (2014). Phylogenetic studies based on molecular data include those of Near et al. (2012), Betancur-R. et al. (2013), Miya and Nishida (2015), and Hughes et al. (2018).

Menopause is an evolutionary mystery: how could living longer with no capacity to reproduce possibly be advantageous? Several explanations have been offered for why female humans, unlike our closest primate relatives, have such an extensive post-reproductive lifespan. Proponents of the so-called "grandmother hypothesis" suggest that older women are able to increase their fitness by helping to care for their grandchildren as allomothers. This paper first distinguishes the grandmother hypothesis from several other hypotheses that attempt to explain menopause, and then develops a formal model by which these hypotheses can be compared and tested by empirical researchers. The model is then modified and used to respond to a common objection to the grandmother hypothesis: that human fathers, rather than grandmothers, are better suited to be allomothers due to their physical strength and a high incentive to invest in their own children. However, fathers-unlike maternal grandmother...
