  No ....not less evolved....as if their is a seeking to attain a golden level of sharkness....an ultimate evolved shark!

  But less evolved as in, they thought that sharks had not been as altered by their enviroment as much as they were.

  Satanus, hit pause....what are you claiming more evolved and less evolved refers to?

  This is it simply... to evolve is to adapt to your enviroment....

  They used to think that sharks had not evolved much because their enviroment didnt alter hugely.

  NOW we see that over time they have actually made significant changes not yet detected, like to their teeth as YOUR link said.

  The quotes from YOUR link that I posted explain it exactly! They had evolved more over time than first thought!

  I don't understand what you are even trying to say! Scientists have been consistant on this since Darwin, you just dont understand it so it is confusing you. That is fine....but don't denounce a whole scientific field, just politely ask for someone to explain it to you!

  No but I was firing up lots of Girls Scout Cookie brand cannabis with a 19%THC-2%CBD content nice for writting I have been taking a lot of CBD rich bud orally and the GSC really loosened me up I see good results in my rythm hand coordination. I think I'm letting my unconscious take over so I never really know what I will write before hand when I'm good and stoned like yesterday. That might account for some of your feeling that I might have been inebriated, my thinking was very antipsycholtic.

  Neurological effects [ edit ]

  A 2010 study found that strains of cannabis containing higher concentrations of cannabidiol did not produce short-term memory impairment vs. strains with similar concentrations of THC, but lower concentrations of CBD. The researchers attributed this attenuation of memory effects to CBD's role as aCB 1 antagonist. Transdermal CBD is neuroprotective in animals. [8]

  Cannabidiol's strong antioxidant properties have been shown to play a role in the compound's neuroprotective and anti-ischemic effects. [9]

  Parkinson's disease

  sychotropic effect [ edit ]

  CBD has anti-psychotic effects and may counteract the potential psychotomimeticeffects of THC on individuals with latent schizophrenia; [5] some reports show it to be an alternative treatment for schizophrenia that is safe and well-tolerated. [11] Studies have shown CBD may reduce schizophrenic symptoms due to its apparent ability to stabilize disrupted or disabled NMDA receptor pathways in the brain, which are shared and sometimes contested by norepinephrine and GABA. [11] [12] Leweke et al.performed a double blind, 4 week, explorative controlled clinical trial to compare the effects of purified cannabidiol and the atypical antipsychotic amisulpride on improving the symptoms of schizophrenia in 42 patients with acute paranoid schizophrenia. Both treatments were associated with a significant decrease of psychotic symptoms after 2 and 4 weeks as assessed by Brief Psychiatric Rating Scale and Positive and Negative Syndrome Scale. While there was no statistical difference between the two treatment groups, cannabidiol induced significantly fewer side effects (extrapyramidal symptoms, increase in prolactin, weight gain) when compared to amisulpride. [13]

  Studies have shown cannabidiol decreases activity of the limbic system [14] and decreases social isolation induced by THC. [15] Cannabidiol has also been shown to reduce anxiety in social anxiety disorder. [16] [17] However, chronic cannabidiol administration in rats was recently found to produce anxiogenic-like effects, indicating that prolonged treatment with cannabidiol might incite anxiogenic effects. [18]

  Cannabidiol has demonstrated antidepressant-like effects in animal models of depression. [19] [20] [21]

  Cancer [ edit ]

  The American Cancer Society says: "There is no available scientific evidence from controlled studies in humans that cannabinoids can cure or treat cancer." [22] Laboratory experiments have been performed on the potential use of cannabinoids for cancer therapy but as of 2013 results have been contradictory and knowledge remains poor. [23] Cannabinoids have been recommended for cancer pain but the adverse effects may make them a less than ideal treatment; two cannabinoid-based medicines have been approved as a backup remedy for nausea associated with chemotherapy.

  viv -

  fundamentalist evolutionist: dogmatist.

  religious minded atheist : an athiest who is willing to see how religious idiom connects to science and that ordinary people theorise (theorise as in seek and form explanatory frameworks for themselves) as much as scientists do and are experts in their own lives and in their arguments.

  edit: to me satanus is simply saying that we need to be more aware that we are continuing to evolve and that evolution is more open-ended than the impression science sometimes gives us in its language and way it dispenses info to the public particularly if some scientitsts are being dogmatic about the evidence and this is crucial for us when we come to form our realities. A big underpinning of science is testibility and falsification (and rightly so)- but we don't proceed in real to live by testability (to that extent) and falsification as in real life this would be very negative. It would also instill a lack of confidence in being able to produce meaning. Imo being able to produce meaning in one's life is absolutely crucial to well being. Actually this latter is another aspect of being a religious minded atheist
