Mating Instabilities Lead to Sympatric Speciation [PDF]

open access: yesarXiv, 2002
One of the most challenging issues of evolutionary biology concerns speciation, the emergence of new species from an initial one. The huge amount of species found in nature demands a simple and robust mechanism. Yet, no consensus has been reached concerning a reasonable disruptive selection mechanism that prevents mixing genes among the emerging ...

Resilience, and positive parenting in parents of children with syndromic autism and intellectual disability. Evidence from the impact of the COVID‐19 pandemic on family's quality of life and parent–child relationships

open access: yesAutism Research, Volume 15, Issue 12, Page 2381-2398, December 2022., 2022
Abstract Family quality of life (FQoL) outcomes collected during the first year of COVID‐19 has been combined with 2018 data to estimate the outbreak's impact on parental outcomes on a sample of 230 families with syndromic autistic children and those with intellectual disabilities (IDs).

The Advantage is at the Ladies: Brain Size Bias-Compensated Graph-Theoretical Parameters are Also Better in Women's Connectomes [PDF]

open access: yesarXiv, 2015
In our previous study we have shown that the female connectomes have significantly better, deep graph-theoretical parameters, related to superior "connectivity", than the connectome of the males. Since the average female brain is smaller than the average male brain, one cannot rule out that the significant advantages are due to the size- and not to the

Brain Gender and Transsexualism [PDF]

open access: yes, 2007
Research by neuroscientists suggests there is a distinction in the BSTc area of the brain between males and females. In transsexual females, those considered male at birth, but who had a strong conviction that they were female, the BSTc region appears to

Bayesian inference in Y-linked two-sex branching processes with mutations: ABC approach [PDF]

open access: yesarXiv, 2018
A Y-linked two-sex branching process with mutations and blind choice of males is a suitable model for analyzing the evolution of the number of carriers of an allele and its mutations of a Y-linked gene. Considering a two-sex monogamous population, in this model each female chooses her partner from among the male population without caring about his type
