“What we’re really interested in is variation among humans in metabolic rates, especially in today’s world of increasing technology and lower levels of physical activity,” said Yegian. “Since we evolved to
Describe evolution. How does it happen? Why was the diversity of species gradual and not instantaneous? If monkeys and humans evolved from a common ancestor, why did we evolve differently? How do mutation, migration, and genetic drift cause the evolution of populations? Be specific and provi...
Modern humans, on the other hand, put more energy into growing the front part of their brains, where all the complex social cognitive processes happen. This allowed them to grow their social networks to a size a Neanderthal might have found difficult to manage. So when caveman problems ...
These accidents happen in spite of many efforts to keep moose off the Alaskan roads. To help maintain moose-free roads, there are wire fences along highways with high traffic. There are also moose underpasses beneath roads to allow for safe crossing and one-way moose gates. But drivers and...
1. Why do genetic mutations happen? 2. What factors do they depend on? Explain why genetic diversity is the raw material for evolution. Describe an example of a human trait that involves both environmental and genetic factors. How is each of the...
Solar Now suddenly, in this context, leaders are being asked to make very important business decisions in the absence of fully understandable data. And in the absence of really even having a pure view of what might happen next, I think we have all been very shaken by the ...
We also need the ability to discern which information is pertinent and which is not, and which comes from reliable sources, and which does not. This can only happen with critical thinkers who have developed and practiced the skills and tools to use information effectively to develop insights. ...
In my book with Peter Gluckman, we also reviewed the plasticity literature and discussed the many different forms of plasticity, how they might have evolved and how they might affect subsequent evolution (Bateson and Gluckman, 2011). Strikingly, all these extensive and varied contributions to the ...
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 ...
Rip out the bias of being first et cetera, and biologists would still say that it won't happen again, at least not in this biosphere. Meanwhile elsewhere, the astrobiologists have just seen (twice!) that planetary populations have a dual distribution, either 4-8 (which we belong ...
