Recent years have seen a rise in research on sexual addiction (SA) and compulsive sexual behaviour (CSB). In the literature, these concepts describe an emerging field of study that may encompass a range of interpersonal and communal consequences for concerned individuals, their intimate partners, f...
Here are other people making “Hitler salutes”, for example Hillary and Kamala. Now you can say that their gestures were different, and didn’t imply approbation of Hitler, but remember what Musk said as he made the gesture: “Thank you for making it happen. My heart goes out to you....
Evolutionary algorithms (EAs) are general-purpose optimisers that come with several parameters like the sizes of parent and offspring populations or the mutation rate. It is well known that the performance of EAs may depend drastically on these parameters. Recent theoretical studies have shown that s...
is “natural”. Ergo, we can’t criticize it. But as I said in my review of Joan Roughgarden’s bookEvolution’s Rainbow, a review published in theTimes Literary Supplement, this argument doesn’t hold water:
In this chapter we address briefly several issues. ■ What is population ageing, and why and how does it occur? ■ The genetics and evolution of ageing – has ageing evolved? ■ What distinguishes ageing from disease? ■ What are the cellular and molecular processes involved with ageing of ...
(a) parent species must always evolvein their entiretyinto descendent species; or (b) descendent species must always out-compete their parent species, driving them to extinction. Both of these scenarios can and do happen, but by no meansalways. If either scenario were always the case, the ...
Why are animals going extinct in the freshwater biomes? How does the loss of amphibians affect humans? Why do amphibians develop scales? Why did the Devonian extinction happen? Why did the Cretaceous extinction happen? Why did marine organisms go extinct millions of years ago?
What causes genetic mutations in populations? Explain how a lack of genetic variation limits evolution. Why would natural selection let a new feature evolve, like a wing, when so many random mutations are needed before it becomes useful t...
Roberta Fusaro:We talked a little bit about some of the incentives and what needs to change. How do we move buyers in that direction? What are some of the initiatives that are already starting to happen? Mark Patel:We have a high level of innovation now taking...
Now that P-22 has been euthanized by wildlife authorities, it’s unclear what will happen to the remains of the famous mountain lion. While government agencies and museum officials consider the final resting place for the cat, the Native American community in Southern California wants P-22 to ...
