About me

Bunny suit

I study the genomes of modern and ancient peoples in order to uncover details of human prehistory. You can learn more about my scientific publications and credentials here and here. I’m also a martial artist, currently training (and occasionally competing) in Muay Thai, boxing, BJJ, and MMA.
This is a blog about my passions: science, conflict, adventure, and interesting people.

    I find comments like the one below here typical of science skepticism:
    This site comprises the same “logic” and “science” worldview that says GMO’s are great and won’t hurt you; fluoride (poison) in your water is good for you; mammograms (radiation) can’t cause cancer (until they admitted that they do…) and nuclear energy will solve all our problems (except for the weapons and the reactor meltdowns and…). Just another part of the same system which currently brings you the NSA, the CIA, ad infinitum. And you get the pleasure of paying for it all… Total insanity.

    Gene modification is what animal husbandry and agriculture has been doing ever since man began using nature in a conscious manner – and even before that, inadvertently.

    Simply by causing selection of certain, desirable traits to create crops or animals better suited to how we want them to be like.

    Take all of agriculture and farming: Many of the species we culture today still exist in their original, wild version. Dogs from Volwes, Cows from Aurox (Aurochs) and so on. Fine examples of what our selection from desirable traits have done. The same applies to nature: for any species, within populatons a process of selection is constantly going on. It is expressed by the term “differential reproductive succes”, i.e. the degree of how success in mating and producing offspring impact on the relative preponderance of traits advantegeous for survival and reproduction. It seems to me that the process is more like “disposal of the less fit” than “survival of the fittest”.

    A simple and easily understood factor like predation is one among all the factors in the process of ‘natural selection’. Carnivores are a threat to their prey – but they also contribute to the health and strength of the species they prey on. Like everywhere in nature, no more energy is spent than required to reach the goal. Therefore a lion will go for the sick and weakest, the easiest to catch from a flock.
