Contrasting life histories contribute to divergent patterns of genetic diversity and population connectivity in freshwater sculpin fishes

BMC Evolutionary Biology, 2018
Background Life history characteristics are considered important factors influencing the evolutionary processes of natural populations, including the patterns of population genetic structure of a species.

Evolution in a changing environment [PDF]

, 2012
We propose a simple model for genetic adaptation to a changing environment, describing a fitness landscape characterized by two maxima. One is associated with "specialist" individuals that are adapted to the environment; this maximum moves over time as ...

Cosmic Perspectives and the Myths We Need to Survive

Journal of Big History, 2019
Big history can be defined as the attempt to understand the integrated history of the cosmos, Earth, life and humanity. Cosmic perspectives and biological evolution are the main scientific ingredients that can convert and broaden history into big history.

Restrictions on biological adaptation in language evolution

, 2009
Language acquisition and processing are governed by genetic constraints. A crucial unresolved question is how far these genetic constraints have co-evolved with language, perhaps resulting in a highly specialized, and species-specific language “module”;

Age structure landscapes emerge from the equilibrium between aging and rejuvenation in bacterial populations

Nature Communications, 2018
Some daughter cells inherit the maternal old pole during bacterial division, but does this correspond to aging? Here, Proenca et al. show that constant patterns of aging and rejuvenation connect distinct growth equilibria within bacterial clonal ...

Alone in the world? Indeed, and liberatingly so

Verbum et Ecclesia, 2021
How do we know that we can trust our viewpoints, our dogmatic principles and our religious convictions to constitute veracity, if not truth? Where can an arbiter be found for our deliberations to establish the trustworthiness of our viewpoints or belief ...

University faculty and their knowledge & acceptance of biological evolution

, 2015
Misconceptions about biological evolution specifically and the nature of science in general are pervasive in our society and culture. The view that biological evolution explains life’s origin(s) and that hypotheses become theories, which then become laws

Directed information panspermia as a possible method of interstellar communication

Frontiers in Astronomy and Space Sciences
The problem of transmitting an interstellar message from one communicative civilization to another is examined, taking into account possible scenarios for the prevalence of civilizations in the Galaxy, including the possibility that Earth’s civilization ...

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

What the Biological Sciences Can and Cannot Contribute to Ethics [PDF]

, 2008
The question whether ethical behavior is biologically determined may refer either to the capacity for ethics (i.e., the proclivity to judge human actions as either right or wrong), or to the moral norms accepted by human beings for guiding their actions.
