Domesticated crops show a reduced level of diversity that is commonly attributed to the "domestication bottleneck"; a drastic reduction in the population size associated with subsampling the wild progenitor species and the imposition of selection pressures associated with the domestication syndrome. A prediction of the domestication bottleneck is a sharp decline in genetic diversity early in the domestication process. Surprisingly, archaeological genomes of three major annual crops do not indicate that such a drop in diversity occurred early in the domestication process. In light of this observation, we revisit the general assumption of the domestication bottleneck concept in our current understanding of the evolutionary process of domestication.

The effects of runs-of-homozygosity on pig domestication and breeding.
BMC Genomics

Key Laboratory of Genetic Evolution & Animal Models and Yunnan Key Laboratory of Molecular Biology of Domestic Animals, Kunming Institute of Zoology, Chinese Academy of Sciences, Kunming, 650223, China.
Background: Since their domestication, recent inbreeding together with intensive artificial selection and population bottlenecks have allowed the prevalence of deleterious mutations and the increase of runs-of-homozygosity (ROH) in domestic pigs. This makes pigs a good model to understand the genetic underpinnings of inbreeding depression.
Results: Here we integrated a comprehensive dataset comprising 7239 domesticated pigs and wild boars genotyped by single nucleotide polymorphism (SNP) chips, along with phenotypic data encompassing growth, reproduction and disease-associated traits.
Stages and causes of the evolution of language and consciousness: A theoretical reconstruction.

This article presents a refinement of theoretical explanations of the main stages of linguistic and cognitive evolution in anthropogenesis. The concepts of language, consciousness, self-consciousness, the self, the unconscious, the subconscious, and the relation between free will and determinism remain at the center of active and complex debates in philosophy and neuroscience. A basic theoretical apparatus comprising the central concepts of "concern" and "providing structure" (an extension of the biological concept of "adaptation") develops the paradigm of the extended evolutionary synthesis.

The genomic natural history of the aurochs.
Nature
November 2024
Smurfit Institute of Genetics, Trinity College Dublin, Dublin, Ireland.
Article Synopsis
- - The aurochs (Bos primigenius), now extinct, was a critical species in prehistoric Eurasian and North African ecosystems and is the ancestor of today's cattle, playing a significant role in providing food and labor for humans over thousands of years.
- - Researchers analyzed 38 ancient genomes, identifying four distinct aurochs populations (European, Southwest Asian, North Asian, and South Asian) that adapted to climate changes and human impacts throughout history.
- - The genetic study revealed that North Asian and European aurochs populations were separated until they mixed after the last glacial period, with domestication originating from a small group of individuals from Southwest Asia, leading to a hybridization with various aurochs strains.
