The definition of a species, is an imprecise one because in reality the slow gradual change in organisms due to evolution blurs the lines.
February 12, 2016 is Darwin Day. Celebrate by learning about and appreciating the beauty of evolution by natural selection.
Nick Lane’s book, “The Vital Question”,tackles some of the toughest questions in biology today, such as the how, and in what environments, life originated, how the complex eukaryotic cell evolved, how the cellular mechanisms to generate energy echo back to the days before biology, and why sexual reproduction is the way it is based constraints placed on us by our energy generating systems -the mitochondria.
Gene drives are an exciting new technique that could allow genetic engineering at the population level. They have the potential of changing entire ecosystems with a engineered gene that will promote its own odds of multiplying throughout the population. A definite “selfish gene”.
If Professor Jeremy England is right, then far from The Second Law of Thermodynamics being a repressor of complexity, it may more accurately be described as an engine of the spontaneous production of organization, complex systems, and life itself.
If the second law of thermodynamics tells us that things tend towards increasing disorder, then how can complex systems, like living cells exist and evolve? We’ll see that these process are not forbidden, but must be accompained by an increase in disorder some where else.
The Clumping Effect is a cognitive bias that demands that when three of more people on the trail pass, they all pass at the same time.
Carl Sagan Day is November 14th 2015. Carl helped instill a love of science and learning in me and gave me my first lesson in scientific skepticism.
To paraphrase Jane Austin, when referring to the RNA that lays hidden at the core of many of our most rudimentary metabolic processes, which may have served a grander role in a far distant past, and which now has relinquished it’s primary role for one of a more modest, behind the scenes assistant, “The sweetest and best of all molecules, faultless in spite of all her faults”.
