    After a Big Fire

    This article (open access I believe) from the local newspaper (The Register-Guard) has several aerial pictures of the landscape, in areas burned by the Holiday Farm Fire (~30 miles from Eugene, where I live). It shows a patchy distribution of burned areas. This is probably good, in that...

    Asking questions about protein structure determination

    Along the lines of the physic based approach, there are additional factors, beyond just the amino acid sequence, that can affect the 3D configuration. Proteins are made from one end to the other. As the forming amino acid string is extruded from the ribosome, the initial groups of amino acids...

    Do plants get any negative sensations when we cut them?

    @KWolf12, that's a very nice description of an entity, like a tree, interacting with its surroundings, and its informational awareness. There's a lot of cool tree-fungus stuff too I guess. Its been done: I think they added a lot of humanistic features to get audience appeal.

    Gorgeous Corona Virus Images

    Here is a Carl Zimmer article in the NY Times showing some fantastic images of the corona virus. These are mostly computer generated images (pretty common these days) based on cryo-EM (Electron Microscopy) and biochemical/molecular biology type data. They are very well rendered, down to the...

    Does Testing Theories Against Data (Evolution and Blood Circulation) Require Math?

    You really want to discount any conclusion that doesn't not involve math. If it doesn't involve math, it doesn't count. Logic as a joke. And, your'e still missing out on the cladistic argument.

    Does Testing Theories Against Data (Evolution and Blood Circulation) Require Math?

    Today cladistic analyses are highly mathematical. At earlier times not so. The most primitive formal cladistic analyses were done by see where traits fell on proposed trees, and only with stable (non-homeoplastic traits-those that don't change much and better reflec tree structure. Prior to...

    Does Testing Theories Against Data (Evolution and Blood Circulation) Require Math?

    This is wrong. It is about a the existence of a hypothesized ancestor. I don't know why you have such difficulty believing this is what I am talking about. The existence of a hypothetical ancestor does not depend upon the mechanisms that underlies evolutionary changes. You keep arguing that I...

    Does Testing Theories Against Data (Evolution and Blood Circulation) Require Math?

    Your response seems to lack any understanding of what it is to consider trait distributions on a phylogenetic tree. Try reading this: Phylogenetic Systematics. which would be this I guess: Your interpretation is wrong. You seem to be thinking of studies on changes in populations frequencies...

    Does the world really need 'more power'?

    There is certainly violence in nature, but not entirely. There are plenty examples of cooperative interactions between organisms (or formerly separate organisms): fungi-tree interactions coral-photosynthetic algae mitocondria-archeal host cell chloroplast-plant cell pregenitor a person- their...

    Does Testing Theories Against Data (Evolution and Blood Circulation) Require Math?

    With math not required, as I have already pointed out: Only if you want to not read, understand, or consider what I am writing, maybe so. The only way you can make that argument with the cladistics example, is if you require to frequencies to replace any determination of whether something is...

    Insights I Know the Math Says so, but Is It Really True?

    What I wrote about analyzing phylogenetic trees using methods like cladistics in fact can do this. This is not a straw man claim. It can certainly be done math free (in simple cases). You seem to be ignoring it, but it directly refutes this claim.

    Does Testing Theories Against Data (Evolution and Blood Circulation) Require Math?

    At the time, those other evolutionary mechanisms were not available. The alternatives were no change or change from Lamarkian mechanisms (for which problematic issues were arising). If the mechanism identified can subsequently be used to further breeding efforts, then it works as a confirmation...
