Innovation from a Memetic and Evolutionary Perspective

open access: yesMednarodno Inovativno Poslovanje, 2019
Innovation happens all around the Universe and is a fundamental mechanism of evolution. Living creatures cannot but exist and develop through innovation. Innovation happens through mutations that make sense in retrospect only.

Natural Selection _In Utero_ Contributes to the Male Longevity Deficit in Contemporary Human Populations [PDF]

open access: yes, 2009
Much literature invokes natural selection to explain the pervasive deficit in the average lifespan of men compared to women.^1^ The explanation assumes that mothers, not fathers, provisioned children over much of human existence, and that women who lived

Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

open access: yesFEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.

Multi‐omics and low‐input proteomics profiling reveals dynamic regulation driving pluripotency initiation in early mouse embryos

open access: yesFEBS Open Bio, EarlyView.
Mouse pre‐implantation development involves a transition from totipotency to pluripotency. Integrating transcriptomics, epigenetic profiling, low‐input proteomics and functional assays, we show that eight‐cell embryos retain residual totipotency features, whereas cytoskeletal remodeling regulated by the ubiquitin‐proteasome system drives progression ...

Putting Process and Product Conceptions of Natural Selection and Genetic Drift to the Test [PDF]

open access: yes, 2013
This paper argues for two claims. First, despite a persistent appearance to the contrary in the philosophy of biology literature, the question of whether natural selection and genetic drift should be defined as processes or as the products (or outcomes)

Alcohol‐induced altered glycans in human tracheal epithelial cells promote bacterial adhesion

open access: yesFEBS Open Bio, EarlyView.
Alcohol induces altered glycans to promote bacteria adhesion. Heavy alcohol drinking is known to increase the risk of bacterial pneumonia. However, the link between alcohol levels and risk of infection remains underexplored. Recently, we found that alcohol induced α2‐6sialo mucin O‐glycans in human tracheobronchial epithelial cells, which mediated the ...

The Biology and Evolution of the Three Psychological Tendencies to Anthropomorphize Biology and Evolution

open access: yesFrontiers in Psychology, 2018
At the core of anthropomorphism lies a false positive cognitive bias to over-attribute the pattern of the human body and/or mind. Anthropomorphism is independently discussed in various disciplines, is presumed to have deep biological roots, but its ...

Future trends in Animal Breeding due to new genetic tecnologies

open access: yes, 2011
The Darwin theory of evolution by natural selection is based on three principles: (a) variation; (b) inheritance; and (c) natural selection. Here, I take these principles as an excuse to review some topics related to the future research prospects in ...
