Dr Andrew Thomas is a senior lecturer of psychology at Swansea University whose research focuses on sex differences and relationship preferences from an evolutionary perspective. Evolution explains a large portion of why we like the things we like. Who we’re attracted to, why we fall into and out of love, how our mental state affects our mating strategies. Therefore, if you are a human who ever intends on being in a relationship, this might be useful. Expect to learn the 5 evolutionary theories which explain much of human mating, whether ChatGPT can correctly predict what traits men and women like most in each other, how many previous sexual partners people say they want their current partner to have had, how open men & women in the West are to polyamorous relationships, how sexual arousal can ruin a faithful relationship and much more… Sponsors: Get 20% discount & free shipping on your Lawnmower 4.0 at https://manscaped.com/modernwisdom (use code MODERNWISDOM) Get over 37% discount on all products site-wide from MyProtein at https://bit.ly/proteinwisdom (use code: MODERNWISDOM) Get 83% discount & 3 months free from Surfshark VPN at https://surfshark.deals/MODERNWISDOM (use code MODERNWISDOM) Extra Stuff: Follow Andrew on Twitter — https://twitter.com/DrThomasAG Get my free Reading List of 100 books to read before you die → https://chriswillx.com/books/ To support me on Patreon (thank you): https://www.patreon.com/modernwisdom #evolution #dating #psychology — 00:00 Intro 01:20 Evolutionary Mismatch 10:18 Evolving Towards Making Small Errors Instead of Big Ones 17:33 Are Men as Picky as Women? 21:55 Is Promiscuity Heritable? 27:32 Humans Engage in Multiple Types of Sexual Strategies 36:49 The Different Levels of Sexual Harassment 46:55 Is Sexlessness in Young Men Caused by Poor Social Skills? 52:56 Attitudes in the West to Having Multiple Sexual Partners 1:04:21 How Many Previous Sexual Partners is Too Much? 1:14:52 What ChatGPT Gets Wrong About Mate Preferences 1:34:31 Where to Find Dr Thomas — Get access to every episode 10 hours before YouTube by subscribing for free on Spotify — https://spoti.fi/2LSimPn or Apple Podcasts — https://apple.co/2MNqIgw Get my free Reading List of 100 life-changing books here — https://chriswillx.com/books/ — Get in touch in the comments below or head to… Instagram: https://www.instagram.com/chriswillx Twitter: https://www.twitter.com/chriswillx Email: https://chriswillx.com/contact/

The advancement of higher cognitive abilities in humans is predominantly associated with the growth of the neocortex, a brain area key to conscious thinking, movement, and sensory perception. Researchers are increasingly realizing, however, that the “little brain” or cerebellum also expanded during evolution and probably contributes to the capacities unique to humans, explains Prof. Henrik Kaessmann from the Center for Molecular Biology of Heidelberg University.

His research team has – together with Prof. Dr Stefan Pfister from the Hopp Children’s Cancer Center Heidelberg – generated comprehensive genetic maps of the development of cells in the cerebella of humans, mice, and opossums. Comparisons of these data reveal both ancestral and species-specific cellular and molecular characteristics of cerebellum development spanning over 160 million years of mammalian evolution.

An anomalous Floquet topological insulator (AFTI) is a periodically driven topological insulator (TI with nonzero winding numbers to support topological edge modes, though its standard topological invariants like Chern numbers are zero.

The photonic lattice constructed by an optical waveguide array fabricated by the femtosecond laser direct writing (FLDW) is an important platform for quantum simulation to realize photonic AFTIs, because the FLDW offers flexible design of true three-dimensional (3D) waveguide structures and precise control of each coupling between waveguides. Moreover, the evolution distance of the lattice can be mapped as the evolution time.

In femtosecond-laser-direct-written photonic AFTIs, selective coupling of adjacent waveguides in a cycle is explicitly defined by the discrete periodically driving protocol. At the complete transfer discrete driving protocol, chiral edge modes co-exist with dispension-less bulk modes, and the lattice energy transfer efficiency of the chiral edge mode is the highest among all TIs (close to 100%), so it is very suitable for the transport of fragile quantum states.

Qi et al. used phage-assisted evolution to optimize SlugCas9, a compact Cas9 nuclease, for NNG PAM recognition and developed a SlugCas9-NNG based adenine base editor for single AAV delivery.

An international team led by researchers at the University of Toronto has uncovered over 100 genes that are common to primate brains but have undergone evolutionary divergence only in humans—and which could be a source of our unique cognitive ability.

The researchers, led by Associate Professor Jesse Gillis from the Donnelly Center for Cellular and Biomolecular Research and the department of physiology at U of T’s Temerty Faculty of Medicine, found the genes are expressed differently in the brains of humans compared to four of our relatives—chimpanzees, gorillas, macaques and marmosets.

The findings, published in Nature Ecology & Evolution, suggest that reduced selective pressure, or tolerance to loss-of-function mutations, may have allowed the genes to take on higher-level cognitive capacity. The study is part of the Human Cell Atlas, a global initiative to map all human cells to better understand health and disease.

Dr. McKinney noted, “With JWST, we can study for the first time the optical and infrared properties of this heavily dust-obscured, hidden population of galaxies because it’s so sensitive that not only can it stare back into the farthest reaches of the universe, but it can also pierce the thickest of dusty veils.”

Did galaxies produce stars in the early universe? This is what a recent study published in The Astrophysical Journal hopes to unveil as a team of international researchers analyze data from NASA’s James Webb Space Telescope (JWST) about a star-forming galaxy called AzTECC71 that existed approximately 900 million years after the Big Bang. What makes this discovery unique is that AzTECC71 is hidden behind a fair amount of dust which initially fooled astronomers to hypothesize that it’s not very big. How astronomers now hypothesize that AzTECC71 was producing a plethora of new stars despite its young age, which challenges previous notions of the formation and evolution of galaxies so soon after the Big Bang.

Can planets form under extreme conditions, such as high levels of ultraviolet radiation? This is something a recent study published in The Astrophysical Journal Letters hopes to find out as a team of international researchers used data obtained from NASA’s James Webb Space Telescope (JWST) as part of the eXtreme Ultraviolet Environments (XUE) JWST program to study the formation and evolution of young planetary systems. This particular study, known as XUE 1, focuses on the star cluster Pismis 24, with the team identifying some key ingredients for life as we know it.

“We find that the inner disk around XUE 1 is remarkably similar to those in nearby star-forming regions,” said Dr. Rens Waters, who is a professor of astrophysics at Radboud University in the Netherlands and a co-author on the study. “We’ve detected water and other molecules like carbon monoxide, carbon dioxide, hydrogen cyanide, and acetylene. However, the emission found was weaker than some models predicted. This might imply a small outer disk radius.”

Protein-like aggregates known as amyloids can bind to molecules of genetic material. It is possible that these two types of molecules stabilized each other during the development of life—and that this might even have paved the way for the genetic code.

How organisms develop from inanimate matter is one of the biggest questions in science. Although many possible explanations have been proposed, there are no definitive answers. That’s no surprise: these processes took place 3 billion to 4 billion years ago, when the conditions on Earth were completely different from today.

“Over this vast period of time, evolution has thoroughly obliterated the traces that lead back to the origins of life,” says Roland Riek, professor of physical chemistry and associate director of ETH Zurich’s new interdisciplinary Center for Origin and Prevalence of Life. Science has no choice but to formulate hypotheses—and to substantiate them as thoroughly as possible with experimental data.
