Evolutionary Biology and Linguistics: The Nature and Implication of a Disciplinary Integration

Studies of the origin and diversification of major groups of plants and animals are contentious topics in current evolutionary biology. This includes the study of the timing and relationships of the two major clades of extant mammals – marsupials and placentals. Molecular studies concerned with marsupial and placental origin and diversification can be at odds with the fossil record. Such studies are, however, not a recent phenomenon. Over 150 years ago Charles Darwin weighed two alternative views on the origin of marsupials and placentals. Less than a year after the publication of On the origin of species, Darwin outlined these in a letter to Charles Lyell dated 23 September 1860. The letter concluded with two competing phylogenetic diagrams. One showed marsupials as ancestral to both living marsupials and placentals, whereas the other showed a non-marsupial, non-placental as being ancestral to both living marsupials and placentals. These two diagrams are published here for the first time. These are the only such competing phylogenetic diagrams that Darwin is known to have produced. In addition to examining the question of mammalian origins in this letter and in other manuscript notes discussed here, Darwin confronted the broader issue as to whether major groups of animals had a single origin (monophyly) or were the result of “continuous creation” as advocated for some groups by Richard Owen. Charles Lyell had held similar views to those of Owen, but it is clear from correspondence with Darwin that he was beginning to accept the idea of monophyly of major groups.

And Linguistics

This book is a historical study of influential currents in the philosophy of language and linguistics of the first half of the twentieth century, explored from the perspective of the English scholar C. K. Ogden (1889–1957). Although no ‘Great Man’ in his own right, Ogden had a personal connection, reflected in his work, to several of the most significant figures of the age. The background to the ideas espoused in Ogden’s book The Meaning of Meaning, co-authored with I.A. Richards (1893–1979), is examined in detail, along with the application of these ideas in his international language project Basic English. A richly interlaced network of connections is revealed between early analytic philosophy, semiotics and linguistics, all inevitably shaped by the contemporary cultural and political environment. In particular, significant interaction is shown between Ogden’s ideas, the varying versions of ‘logical atomism’ of Bertrand Russell (1872–1970) and Ludwig Wittgensten (1889–1951), Victoria Lady Welby’s (1837–1912) ‘significs’, and the philosophy and political activism of Otto Neurath (1882–1945) and Rudolf Carnap (1891–1970) of the Vienna Circle. Amid these interactions emerges a previously little known mutual exchange between the academic philosophy and linguistics of the period and the practically oriented efforts of the international language movement.

Character Identity

Homology—a similar trait shared by different species and derived from common ancestry, such as a seal's fin and a bird's wing—is one of the most fundamental yet challenging concepts in evolutionary biology. This book provides the first mechanistically based theory of what homology is and how it arises in evolution. The book argues that homology, or character identity, can be explained through the historical continuity of character identity networks—that is, the gene regulatory networks that enable differential gene expression. It shows how character identity is independent of the form and function of the character itself because the same network can activate different effector genes and thus control the development of different shapes, sizes, and qualities of the character. Demonstrating how this theoretical model can provide a foundation for understanding the evolutionary origin of novel characters, the book applies it to the origin and evolution of specific systems, such as cell types; skin, hair, and feathers; limbs and digits; and flowers. The first major synthesis of homology to be published in decades, this book reveals how a mechanistically based theory can serve as a unifying concept for any branch of science concerned with the structure and development of organisms, and how it can help explain major transitions in evolution and broad patterns of biological diversity.

Formation Game

Engaging students in language activities can sometimes be challenging for language educators. One of the ways to engage students in language activities is through language games. Language games can motivate students to communicate, strengthens their ability to comprehend the language and enhance their problem-solving and cognitive skills. Language games also have a vast potential to increase engagement of the students, thus lead to the creation of the Conquer & Score: The Derivational Island. It is a word formation enrichment game catering to students learning lexicology and linguistics. The topic was chosen based on the result of an online quiz on the types of morphemes. The game focuses on the derivational morphemes used to form the English language words. The game requires knowledge of morphology as well as basic lexical analysis skills. The game provides educators a fun and engaging reinforcement activity for the students. Gamification elements used in the game such as rewards, flexible learning path and progress indicator offer a safe environment for competition, which can motivate students to outdo each other to win the game. This paper also highlights some important aspects of games in learning.
