  1. Francisco J. Ayala (1970). Teleological Explanations in Evolutionary Biology. Philosophy of Science 37 (1):1-15.
    The ultimate source of explanation in biology is the principle of natural selection. Natural selection means differential reproduction of genes and gene combinations. It is a mechanistic process which accounts for the existence in living organisms of end-directed structures and processes. It is argued that teleological explanations in biology are not only acceptable but indeed indispensable. There are at least three categories of biological phenomena where teleological explanations are appropriate.

  4. Francisco J. Ayala (1987). The Biological Roots of Morality. Biology and Philosophy 2 (3):235-252.
    The question whether ethical behavior is biologically determined may refer either to thecapacity for ethics (e.i., the proclivity to judge human actions as either right or wrong), or to the moralnorms accepted by human beings for guiding their actions. My theses are: (1) that the capacity for ethics is a necessary attribute of human nature; and (2) that moral norms are products of cultural evolution, not of biological evolution.Humans exhibits ethical behavior by nature because their biological makeup determines the presence (...)

    William Paley ( Natural Theology , 1802) developed the argument-from-design. The complex structure of the human eye evinces that it was designed by an intelligent Creator. The argument is based on the irreducible complexity ("relation") of multiple interacting parts, all necessary for function. Paley adduces a wealth of biological examples leading to the same conclusion; his knowledge of the biology of his time was profound and extensive. Charles Darwin’s Origin of Species is an extended argument demonstrating that the "design" of (...)

    This paper sets forth a familiar theme, that science essentially consists of two interdependent episodes, one imaginative, the other critical. Hypotheses and other imaginative conjectures are the initial stage of scientific inquiry because they provide the incentive to seek the truth and a clue as to where to find it. But scientific conjectures must be subject to critical examination and empirical testing. There is a dialogue between the two episodes; observations made to test a hypothesis are the inspiration for new (...)

    Francisco J. Ayala, The Structure of Evolutionary Theory: On Stephen Jay Gould's Monumental Masterpiece.
    Stephen Jay Gould’s monumental The Structure of Evolutionary Theory ‘‘attempts to expand and alter the premises of Darwinism, in order to build an enlarged and distinctive evolutionary theory . . . while remaining within the tradition, and under the logic, of Darwinian argument.’’ The three branches or ‘‘fundamental principles of Darwinian logic’’ are, according to Gould: agency (natural selection acting on individual organisms), efficacy (producing new species adapted to their environments), and scope (accumulation of changes that through geological time yield (...)

    Knives, birds' wings, and mountain slopes are used for certain purposes: cutting, flying, and climbing. A bird's wings have in common with knives that they have been 'designed' for the purpose they serve, which purpose accounts for their existence, whereas mountain slopes have come about by geological processes independently of their uses for climbing. A bird's wings differ from a knife in that they have not been designed or produced by any conscious agent; rather, the wings, like the slopes, are (...)

    Erect posture and large brain are two of the most significant anatomical traits that distinguish us from nonhuman primates. But humans are also different from chimpanzees and other animals, and no less importantly, in their behavior, both as individuals and socially. Distinctive human behavioral attributes include tool-making and technology; abstract thinking, categorizing, and reasoning; symbolic (creative) language; self-awareness and death-awareness; science, literature, and art; legal codes, ethics and religion; complex social organization and political institutions. These traits may all be said (...)

    The theory of punctuated equilibrium has been proposed as a challenge to the modern synthesis of evolutionary theory. Two important issues are raised. The first is scientific: whether morphological change as observed in the paleontological record is essentially always associated with speciation events. This paper argues that there is at present no empirical support for this claim: the alleged evidence is based on a definitional fallacy. The second issue is epistemological: whether macroevolution is an autonomous field of study, independent from (...)

    We explore the distinctive characteristics of Mexico's society, politics and history that impacted the establishment of genetics in Mexico, as a new disciplinary field that began in the early 20th century and was consolidated and institutionalized in the second half. We identify about three stages in the institutionalization of genetics in Mexico. The first stage can be characterized by Edmundo Taboada, who was the leader of a research program initiated during the Cárdenas government (1934-1940), which was primarily directed towards improving (...)

    This article seeks to show how several rhetorical tools were used and, in fact, played a central role in the argumentation advanced by Niles Eldredge and Stephen Jay Gould in their 1972 seminal article on the theory of Punctuated Equilibria. It is analyzed how Eldredge and Gould proceeded through three steps that, sequentially integrated, made their argument compelling. It is shown how they made use of analogies, metaphors and other rhetorical tools. It is sustained that they began by priming the (...)

    Human Evolution provides a comprehensive overview of hominid evolution, synthesising data and approaches from fields as diverse as physical anthropology, evolutionary biology, molecular biology, genetics, archaeology, psychology and philosophy. The book starts with chapters on evolution, population genetics, systematics, and the methods for constructing evolutionary trees. These are followed by a comprehensive review of the fossil history of human evolution since our divergence from the apes. Subsequent chapters cover more recent data, both fossil and molecular, relating to the evolution of (...)
