  • Clonar humanos? Límites de la eugenesia

    Open AccessFrancisco J AyalaARTICLEArbor2019References: 7

    La humanidad no solo ha evolucionado, sino que continúa evolucionando. ¿Hacia dónde va la evolución humana? La evolución biológica está dirigida por la selección natural, que no es un proceso benevolente que guíe a las especies hacia un éxito seguro. El resultado final puede ser la extinción. Los avances en genética, biología molecular y biomedicina han hecho posible manipular, rápida y efectivamente, la constitución genética de la humanidad. La …

  • Las herramientas nos hicieron humanos. El papel de la tecnología en la evolución biológica y social del género Homo

    Open AccessCamilo José Cela Conde, Francisco J AyalaARTICLESociología y tecnociencia2018

    Las tendencias disciplinares son, en el terreno de la ciencia, caminos difíciles de esquivar. Pocos lectores interesados en la sociología se detendrán a pensar que tiene sentido poner el énfasis en la condición del ser humano como usuario de herramientas o, en general, de la tecnología, por lo obvio que resulta esa relación entre las personas y las máquinas. Este artículo centra su interés en estas cuestiones

  • Miocene and Lower Pliocene hominins

    Francisco J Ayala, Camilo J Cela‐conde et al.BOOKProcesses in Human Evolution2017

    This chapter first introduces the different genera and species within the hominin tribe that will be considered, as well as their immediate ancestors, which they shared with African apes. Next is the description and interpretation of the Miocene hominin fossil exemplars that belong to the genera Sahelanthropus (Chad), Orrorin (Kenya), and Ardipithecus (Ethiopia). The deposits of Toros Menalla, Tugen Hills, and Aramis are analyzed from a stratigra…

  • Middle and Lower Pleistocene: The Homo radiation

    Francisco J Ayala, Camilo J Cela‐conde et al.BOOKProcesses in Human Evolution2017

    This chapter deals with the radiation of the genus Homo after its exit from Africa. It deals with population dispersals and the meaning of the taxon Homo erectus with respect to the African and Asian fossils. The morphological characterization of H. erectus is complemented with other sorts of evidence, such as fossil footprints. The comparison between the Asian and African specimens suggests the possible existence of the taxon Homo ergaster . The…

  • Hominin transition to Upper Pliocene

    Francisco J Ayala, Camilo J Cela‐conde et al.BOOKProcesses in Human Evolution2017

    This chapter analyzes the transition of the hominins from the Middle Pleistocene to the Late Pleistocene. Two alternative models are explored, the “Multiregional Hypothesis” (MH) and the “Replacement Hypothesis,” and how each model evaluates the existing relationships between the taxa Homo neanderthalensis and Homo sapiens . Next is the investigation of the transitional (or “archaic,” if this grade is taken into account) exemplars found in Europe…

  • The emergence of the genus Homo

    Francisco J Ayala, Camilo J Cela‐conde et al.BOOKProcesses in Human Evolution2017

    This chapter’s focus is the emergence of the genus Homo in the Pliocene, proposing Homo habilis as the oldest species. The features of the H. habilis taxon are examined by means of the specimens from Olduvai and Koobi Fora. Next, the presence is considered of other early Homo taxa in the Rift ( H. rudolfensis ), South Africa ( H. gautengensis and H. naledi ), and, outside Africa, in Georgia ( H. georgicus ). The last part of the chapter investiga…

  • Lithic traditions: Tool-making

    Francisco J Ayala, Camilo J Cela‐conde et al.BOOKProcesses in Human Evolution2017

    This chapter is dedicated to the lithic traditions. It analyzes the pre-cultural cores and flakes produced by chimpanzees for cracking nuts and the evidence of their using bones as tools. Next, the chapter describes the first lithic tradition (Mode 1 or Oldowan), the transition from Mode 1 to 2 (Acheulean culture), and the process for producing the first Acheulean tool, the biface. Mode 2 dispersal separates, by means of the “Movius line,” the lo…

  • Species of the Upper Pleistocene

    Francisco J Ayala, Camilo J Cela‐conde et al.BOOKProcesses in Human Evolution2017

    This chapter analyzes the two taxa of the Upper Pleistocene: Homo neanderthalensis and Homo sapiens . The first one is explored starting with the Feldhofer discovery and the early interpretations of that specimen. The next issue is the evolutionary model of the Neanderthals and their geographic range. The ensuing questions are the Neanderthal morphology, its ontogenetic development, and the relationship between its traits and its adaptive strateg…

  • Middle and Upper Pliocene hominins

    Francisco J Ayala, Camilo J Cela‐conde et al.BOOKProcesses in Human Evolution2017

    This chapter analyzes the hominins of the Middle and Upper Pliocene, encompassing a considerable diversification of the genus Australopithecus , which is polyphyletic; it brings also into consideration the exemplars from South Africa and Chad. The contrast between “gracile” and “robust” exemplars among the South African fossils brings about the description of the Paranthropus genus, with African (P. robustus ) and Rift species ( P. boisei and P. …

  • Taxonomy

    Francisco J Ayala, Camilo J Cela‐conde et al.BOOKProcesses in Human Evolution2017

    This chapter examines the hominin tribe as it branches off within the hominoid diversification. It considers the differences between humans and chimpanzees, and explores the systems of classification of the human lineage. Next come the different adaptive strategies of the various genera of the human lineage. An outcome of different adaptations are the derived characteristic human traits, from large brains to bipedalism, which is the only apomorph…

  • Processes in Human Evolution

    Francisco J Ayala, Camilo J Cela‐conde et al.BOOKProcesses in Human Evolution2017

    Processes in Human Evolution is a fully reconsidered treatment of Human Evolution , the previous book by the same authors published by OUP in 2007. The major discoveries of the last decade have necessitated a completely revised view of how to understand human evolution, incorporating the advances in genetics, paleontology, ecology, archaeology, geography, and climate science. The genera Sahelanthropus, Ardipithecus, Orrorin, Australopithecus, Par…

  • Neanderthals and modern humans: The journey from early hominins to Neanderthals and modern humans

    Francisco J Ayala, Camilo José Cela Conde et al.BOOKProcesses in Human Evolution2017Cited by: 86

    This chapter deals with the similarities and differences between Homo neanderthalensis and Homo sapiens , by considering genetic, brain, and cognitive evidence. The genetic differentiation emerges from fossil genetic evidence obtained first from mtDNA and later from nuclear DNA. With high throughput whole genome sequencing, sequences have been obtained from the Denisova Cave (Siberia) fossils. Nuclear DNA of a third species (“Denisovans”) has bee…

  • On Human Nature: Biology, Psychology, Ethics, Politics, and Religion

    Francisco J Ayala, Michel TibayrencBOOKOn Human Nature2016

    "Covers the present state of knowledge on human diversity and its adaptive significance through a broad and eclectic selection of representative chapters. This transdisciplinary work brings together specialists from various fields who rarely interact, including geneticists, evolutionists, physicians, ethologists, psychoanalysts, anthropologists, sociologists, theologians, historians, linguists, and philosophyers. Genomic diversity is covered in s…

    Open AccessAna Barahona, Francisco J AyalaARTICLEArbor1997

    La idea de progreso en Biología está ligada al concepto de scala naturae o la gran cadena del ser que se puede trazar hasta Aristóteles. Esta noción de que los organismos vivientes pueden clasificarse en una jerarquía de inferior a superior tomó formas nuevas en los siglos XVII y XVIII. En el siglo XVIII, naturalistas como Buffon, Bonnet y Robinet se habían preguntado si podíamos hablar de un patrón definido de desarrollo. En el siglo XIX, Lamarc…
