Human Body


The human brain. Could it have evolved?

Science would have you believe that the most complex organ in the body evolved. How can something, that is the control center for the rest of the body, evolve over millions of years? When the other parts of the body are dependant upon it in order to even function? It would have to evolve "first" in order for all to connect to it and work. But, because it is so complex, it would take more mutations (a lot more) to form. Therefore, it would take the longest to evolve. Besides, how would the brain know the other organs existed, and it needed to control them?

And how would the nervous system know what part of the brain to connect to in order the organ to work? For if the heart gets hooked to the vision center of the brain, will we see through our chest, or will we die? And if the nervous system worked so well with connections, everyone that becomes paralyzed, would become better. But they don't. Which proves that someone had to route the nerves through the body, to the correct organs, so they will function.



Regions of the brain, and what they do.


Frontal Lobe  
  • the primary motor cortex of the frontal lobe controls movement of the body parts
  • the prefrontal cortex has an important part in memory, concentration, temper, intelligence and personality
  • the premotor cortex is beside the primary motor cortex and guides our eye and head movements and sense of orientation
  • Broca's area is important in language production

Occipital Lobes  
  • contains the visual cortex
  • the right side of the brain 'sees' the left visual space, whereas the left side of the brain 'sees' the right visual space
  • the visual cortex aides in the recognition of visual objects

Temperal Lobes  
  • contains the auditory cortex helps that receives signals from the ear and lets us hear sounds and associate meanings with sounds
  • responsible for memory
  • the Wernicke's area is important for language and speech

Parietal Lobes
  • coordinates signals received from other brain regions to interpret sensory signals
  • coordination of visual, auditory, motor and sensory signals along with memory helps to identify objects  
  • Cerebellum
    • important in refining movements, balance, equilibrium and posture
    • controls muscle tone and body position
    • tumors or lesions here may cause jerky movements

    Brain stem
    • relay station connecting much of the body (via the spinal cord) to the cerebrum
    • considered a 'primitive' structure of the brain
    • together with the thalamus control wakefulness, attentiveness and sleep pattern


      • ocular motion


      • eye and facial movements
      • facial sensation
      • hearing
      • balance

    Medulla oblongata

      • breathing
      • blood pressure
      • heart rhythms
      • swallowing

    Pituitary Gland

    Also known as the 'Master gland', responsible for secreting numerous hormones

    • growth hormone (GH, somatotropin)
    • luteinizing hormone (LH)
    • prolactin (PRL)
    • adrenocorticotropic hormone (ACTH)
    • thyroid stimulating hormone (TSH)
    • follicle stimulating hormone (FSH)
    • melanocyte stimulating hormone (MSH)
    • antidiuretic hormone (ADH)
    • oxytocin
    isolation of hormones from this gland (which is in part an extension of the brain) and subsequent injection into humans was responsible for an outbreak of iatrogenic CJD 

  • helps to control the pituitary gland and thus hormone secretion
  • controls eating behavior, sexual behavior, sleeping and body temperature  
  • Pineal Gland  its function in humans is still unclear but may aid in dark light responses and cycles

    Thalamus  relay station for pain sensation and alertness

    Spinal Cord
    • the spinal cord receives information from skin, joints, and muscles
    • sends back signals for both voluntary and reflex movements
    • transmits signals from internal organs to the brain and from the brain to internal organs
    • connects the brain to peripheral organs and tissue
    • in addition, the spinal cord contains
      • ascending pathways through which sensory information reaches the brain
      • descending pathways that relay motor commands from the brain to motor neurons


    As you look at each part of the brain and realize that it's functions are vital. Can you see even one function you can do without? In the evolution process, this is where the problem lies. Over the billions of years of evolution, the brain at different points was not fully functional, until fully evolved. And with all the main organ functions that it controls, the evolving human had to do without some of these that would be dependant upon for survival, but did not work. Example:

    1) Can you have eyes and see without the vision center of your brain not working?

    2) Can you heart beat without the brain stem fully evolved?

    3) Can you breathe without the brain stem fully evolved?

    4) Will your pancreas know how much insulin to inject into the body at any given time?

    5) etc....

    Connect the dots between the organs of your body, and the parts of your brain that controls it, and you'll start to see the picture. It either came together all at once, or it did not came together at all. Because for one vital organ to not work, when needed, would cause either sudden death, or a slow death. And how can something evolve, mutate, or natural selection work, when the evolving subject just keeps dying? In other words, when the evolving subject reaches a point to where it is solely dependant on it's organs, and it's brain to control them to function in sync. If they don't, evolving subject dies. And no natural selection takes place, and said subject does not evolve past a point that keeps killing it. So my question would be: How does the evolving subject get past the point that keeps killing it?

    Brain facts:

    You have 100 000 million brain cells. Nerve messages move at 240 mph. If you could harness the power used by your brain, you could power as a 10-watt light bulb. We remember one trillion things in a lifetime. 

    There are 1 quadrillion synapses in the human brain. That's 1,000,000,000,000,000 synapses! This is equal to about a half-billion synapses per cubic millimeter (a nickel is about 1mm thick). So, in a little box-like space in your brain that is 1 millimeter on all sides, you have 500 millions gaps helping you calculate everything you do, like whether you brushed your teeth yet. These synapses change all the time and underlie your reality and growth to higher states of consciousness (Statistic from Changeux, J-P. and Ricoeur, P., "What Makes Us Think?", Princeton: Princeton University Press, 2000, p. 78.)

    The total length of wiring between neurons is 100,000 kilometers. Most of that is the cerebral cortex talking to itself. These fibers interconnect the vast array of neural computers and create wholeness out of infinite points of dynamism. (Statistic from Coveney, P. and Highfield, R., "Frontiers of Complexity. The Search for Order in a Chaotic World," New York: Fawcett Columbine, 1995, p. 283.).

    Human body and water facts:

    • Water is the only substance on earth found naturally in three forms  solid, liquid and gas.
    • A dairy cow has to drink 4 gallons of water to produce 1 gallon of milk.
    • Cold water is absorbed into the body faster than warm water.
    • Driving a car in the city typically results in the loss of as much as half a litre of water an hour which can trigger emotional changes that can lead to road rage. (Source: the National Mineral Water Information Service)
    • We can lose up to 2 litres of water in 40 minutes when exercising.
    • Even at rest skin your skin can lose up to half a litre of water into the atmosphere every day, and during hot weather it will lose even more.
    • Your brain tissue is 85% water. Messages from your brain to everywhere else in your body are transported on waterways.
    • Humans lose the equivalent of a pint or more of water every day just breathing.
    • The human body is comprised of around 75% water at birth, but this can reduce to 55% by the end of a persons life. This is most visible from the wrinkling of the skin.
