Buzz off

Why do flies that enter your house in summer do so in such an ostentatious way, with loud and frenetic buzzing? Surely it would be better for their survival if they didn't? Is there a purpose to this display?

Why does each hemisphere of the brain control of the opposing side of the body?

In humans, and I assume most other animals, the right side of the brain receives sensory information from and exerts motor control over the left side of the body. This necessitates neurons to cross the midline at some point within the CNS to reach the appropriate side. But why has this evolved? It seems unnecessary and possibly more unstable than controling the ipsilateral body hemisphere.

Why do so many people cross their legs?

Looking around at a meeting recently, I noticed that almost everybody (men and women, from various European countries) was sitting with their legs crossed. Others had their ankles crossed. Humans did not evolve to sit on chairs, so what is it that makes this position so common and comfortable? Do people from all cultures, whether or not crossing legs is culturally acceptable, all feel tempted to cross their legs or ankles when sitting on chairs?

evolution: animal intelligence, land vs water

Could an animal as intelligent and advanced as humans have evolved over time if nothing had ever evolved to live on land?

Or, could it be possible for any current aquatic animal to evolve over time to a stage where it was as intelligent and advanced as humans?

Slap it on (or not)

What evolutionary, or indeed any other, reasons are there why women tend to wear make-up and men in general do not?

Adaptive advantage of inbreeding

Is there any relation between the greater gentic variance due to inbreeding and the environment? For example, say a species is near extinction due to poor evolutionary fitness. Their population dwindles until inbreeding becomes more common. Is the greater likelihhod of genetic mutation itself an evolutionary trait, oe simply coincidence?

Inbreeding and evolution

Does the genetic variance of inbred offspring have any relation to the need to adapt to the environment in dwindling species' groups, or is it just a coincidence?

My Theory of Human Evolution and the possibility of Time travel/UFO sightings

Perspective on “The Theory of Evolution: Linear Space and Time Relevance”

By: Tracey Gamer Fanning

 

My theory is based on the general principal of linear time and the continuation of human and technological evolution.

 

If you look at space as one unit – not a multiple number of infinite galaxies and space, but one unit that spans all time, than that unit continues to evolve on a linear time scale.

 

If you look at biological existence from the beginning of the earth’s formation, i.e. the beginning of our timeline, then you can follow a logical timeline of evolution. Biological formation started millions and millions of years ago with single celled organisms. Following the development of life’s existence, i.e. human existence, you can see the development of man.

 

On the homo-erectus time line, following a chimp like organism, through caveman homo-erectus evolution, through modern erect man, you can see all of the changes that have occurred over millions of years. For example, standing upright, loss of body hair, the formation of longer slimmer limbs, and less clublike hands with more nimble agile digits.

 

If you logically follow a simple timeline method, the evolution of our existence, over the course of millions of years, added to the evolution of our technology, added to the geographical anomalies, we can predict millions of evolutionary patterned timelines.

 

But if you consider one hypothetical timeline, you see the human bodies over time getting larger, living longer periods of time, increase in brain mass and function. Added to the advancement of technology and you can hypothesize the evolution of time travel.

 

If we are just looking at the evolutionary process over millions of years, on a singular spacial system, then, why do we assume that all of the countless “sightings” of UFO’s are from other planetary systems? Why can’t we, as human beings, possibly realize that as one singular system, Earth, quite possibly, is the only planet that can sustain a human-like life form, therefore, any beings that would be considered “alien” could actually be our own human race, from millions of years in the future (Humanlike characteristics, large hairless heads, on larger bodies, in devices that can travel back in time.)

 

Leading to a conclusion, that anyone who has ever claimed to have been “abducted” by space creatures, are just relics of a long past time, that are being studied by future Anthropologists, and then returned to our own time.

 

Like an Anthologist from 2011, being able to dig up a caveman, do studies on that creature, and then returning it to its own, time, family/clan and environment. We could study our ancestry without disturbing evolution itself.

 

Consider this, if you were a caveman, how would you describe a being, standing completely upright, wearing the latest in space wear, potentially from the Gap, with just hair on our heads, with long thin arms, able to sedate, study, and return unharmed to its clan to continue its normal path of evolution without disturbing or interfering with the normal timeline of human existance?
