PROBLEMS OF CULTURAL EVOLUTION [PDF]

Evolution, 1958
This paper is concerned with the biological factor in cultural evolution, with possible ways in which inherent physical, physiological and psychological characteristics shared by all human beings have conditioned culture and channeled the direction of its development.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Experimental and archaeological assessment of use-wear persistence on burnt flint from Tinshemet Cave

Scientific Reports
Fire plays a central role in human evolution and site formation, yet its impact on the preservation of microscopic use-wear remains poorly understood.

Old and New Approaches to Animal Cognition: There Is Not “One Cognition”

Journal of Intelligence, 2020
Using the comparative approach, researchers draw inferences about the evolution of cognition. Psychologists have postulated several hypotheses to explain why certain species are cognitively more flexible than others, and these hypotheses assume that ...

Canoes and cultural evolution [PDF]

Proceedings of the National Academy of Sciences, 2008
Over the last 30 years, the idea that the processes producing cultural stability and change are analogous in important respects to those of biological evolution has become increasingly popular. Biological evolution is characterized by changing frequencies of genes in populations through time as a result of such processes as natural selection; likewise,

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

FEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

The evolutionary dynamics of how languages signal who does what to whom

Scientific Reports
Languages vary in how they signal “who does what to whom”. Three main strategies to indicate the participant roles of “who” and “whom” are case, verbal indexing, and rigid word order.

Joint Action Enhances Cohesion and Positive Affect, but Suppresses Aspects of Creativity When Combined With Shared Goals

Frontiers in Psychology, 2019
We aimed to examine the link between two types of joint action (synchrony and asynchrony) and creativity (both divergent thinking and convergent thinking) using an established experimental paradigm.

Darwinism and the Cultural Evolution of Sports [PDF]

Perspectives in Biology and Medicine, 2009
This article outlines a Darwinian approach to sports that takes into account its profoundly cultural character and thereby overcomes the traditional nature-culture dichotomies in the sociology of sport. We argue that there are good reasons to view sports as culturally evolved signaling systems that serve a function similar to (biological) courtship

Rab14 regulates the transport of human papillomavirus to the trans‐Golgi network for infectious cell entry

FEBS Letters, EarlyView.
This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.
