Towards a mechanistic foundation of evolutionary theory [PDF]

open access: yeseLife, 2017
Most evolutionary thinking is based on the notion of fitness and related ideas such as fitness landscapes and evolutionary optima. Nevertheless, it is often unclear what fitness actually is, and its meaning often depends on the context.

The selection force weakens with age because ageing evolves and not vice versa

open access: yesNature Communications, 2022
A decline of selection with age is generally seen as the reason that ageing evolves. But selection can also increase with age. What happens then? This work shows that ageing nevertheless evolves, and so does the decline of selection with age.

Fixation probabilities in network structured meta-populations

open access: yesScientific Reports, 2021
The effect of population structure on evolutionary dynamics is a long-lasting research topic in evolutionary ecology and population genetics. Evolutionary graph theory is a popular approach to this problem, where individuals are located on the nodes of a

Synthetic Symbiosis under Environmental Disturbances

open access: yesmSystems, 2020
By virtue of complex ecologies, the behavior of mutualisms is challenging to study and nearly impossible to predict. However, laboratory engineered mutualistic systems facilitate a better understanding of their bare essentials.

A common gene drive language eases regulatory process and eco-evolutionary extensions

open access: yesBMC Ecology and Evolution, 2021
Background Synthetic gene drive technologies aim to spread transgenic constructs into wild populations even when they impose organismal fitness disadvantages. The extraordinary diversity of plausible drive mechanisms and the range of selective parameters

The birth of a bacterial tRNA gene by large-scale, tandem duplication events

open access: yeseLife, 2020
Organisms differ in the types and numbers of tRNA genes that they carry. While the evolutionary mechanisms behind tRNA gene set evolution have been investigated theoretically and computationally, direct observations of tRNA gene set evolution remain rare.

Why is cyclic dominance so rare?

open access: yeseLife, 2020
Natural populations can contain multiple types of coexisting individuals. How does natural selection maintain such diversity within and across populations?

Optimizing crop rotations via Parrondo’s paradox for sustainable agriculture

open access: yesRoyal Society Open Science, 2023
Crop rotation, a sustainable agricultural technique, has been at humanity’s disposal since time immemorial and is practised globally. Switching between cover crops and cash crops helps avoid the adverse effects of intensive farming.

The Bio-Evolutionary Approach to Religions: A Study of David Wilson's Perspective [PDF]

open access: yesپژوهشنامه فلسفه دین, 2021
Biologically, one of the most important and distinguishing features of human beings compared to early mammals is culture, which includes political and social institutions, religious and moral traditions.
