  1. When DNA sequences of the same conserved gene in multiple species are aligned ( called BLAST analysis ), the specific differences can be identified and quantified. The differences are small but detectable in similar species and more and more numerous in more different species. Cladograms (family trees) can be created from this which match very well with cladograms from purely morphological data.
  2. It shouldn't be a topic of opinion, but the primary data is not brought up often enough, so people have to take each others word, and argue by authority.
  3. This is my own conjecture based on anecdotal evidence, but if I were researching this I would look in these directions. Schizophrenia is related to communication between the left and right brains. Not sure if it is opening the bridge, closing the bridge, enhancing the less dominant side, dimming the dominant side, or something else. Dominant side being where the primary language center and self-identification of consciousness resides. Cannabis plays into 1 or more of these pathways. It appears to make imagination (or, just activity of the less dominant brain) more vivid (accessibl
  4. a blender Edit: To add to this, there are a variety of tools that all use mechanical shearing forces. homogenizer - literally a blender. Used in bursts and in a ice-cold container to prevent cooking. sonicator - uses sound, actually high frequency vibrations, to shake apart cells microfluidizer - pushes an already homogenized sample down a narrow tube, then quickly expands the other end in a vacuum, ripping apart even sub-cellular structures.
  5. 1. Those chromosome numbers for horse and donkey of 64 and 62 are diploid numbers meaning they received 1/2 from each parent. The hybrid mule receives 32 from its horse parent and 31 from its donkey parent totalling 63. The completely hypothetical evolution of donkeys into horses may be explained in only one mutation event. Imagine one chromosome of a donkey gamete split in 2. The offspring would have 31+32=63 chromosomes. If this offspring was still fertile (this isn't a mule yet) it may supply 31 or 32 chromosomes. But imagine it passed on 32 to a few children, and some of those child
  6. Why can humans handle advanced maths? One of humans greatest gifts is their ability to break events into component architectures. Together, they form context. This ability is one feature of creative problem solving by allowing components of multiple systems to be combined in a novel system. Another gift, which may just be a product of the previous, is the ability to assess the utility of a system, potentially due to the cognition that the system is not concrete because the components may be rearranged. Because systems can be assigned utility, they can be compared to one another. Maths
