Watch this video animation
of cell functions related to leukocyte extravasation
the mechanisms that allow a white blood cell to sense its surroundings and respond to an external stimulus". (Translation: How your body gets the germ fighting white blood cells to where they are needed.)
Most of us won't understand it all*, but you will get a sense of how intricate our cells and body are. Animation begins at about the 3:20 minute mark. My favorite section was at about the 3:50 minute mark where the motor protein
literally walked up
, hauling a huge membrane bound cargo vesicle
to its destination! (David Bolinsky, one of the animators, called it the FedEx guy of the cell.) Truly amazing.
This video clip came from Dr. Mercola's website
and was produced by The Howard Hughes Medical Institute. In other words, it has no connection to Christianity, Creation Science or the Intelligent Design movement. It was produced to help cellular biology students understand the workings of the cell. (I subscribe to Dr. Mercola's website because I am interested in Natural Medicine. His website is not Christian based however, therefore some info I accept, some I reject.)
Yet, when you watch all the intricate steps of just getting a white blood cell to the location it is needed, it is pretty obvious those steps were all designed and orchestrated--they couldn't happen by accident.
The last section of the video shows how the leading edge of the rolling white blood leukocyte flattens and spreads at the proper spot, allowing it to slip through the space between the endothelial cells, escaping the blood vessel wall to get to the site of infection.
If all of what we see and are is the product of random chance--evolution--how did those early organisms survive infection? How did those early cells exist without these complex, well orchestrated, mechanisms?
Since both Evolution and Creation require faith, I think it was a lot easier to believe in evolution when cells were thought to be simple structures seen under primitive lenses and microscopes in the 1800s. But once the electron microscope came on the scene, we then became aware of the complex anatomy and physiology (structure and function) of these supporting cellular structures, the human genome, and on the physical side of science, the sub atomic level of atoms.
I believe the more we are able to see into these tiny worlds, the more complex we will find them: the mechanisms featured in the video will have their own minute support structure. Dr. DeYoung also stated his belief in the intricacy of the unseen world yet to be discovered.
And that brings me to my REPORT on Dr. Don DeYoung's seminar on Design From Nature
last night. He was a dynamo of information and presented it in a lively manner.
He informed us that scientists and inventors are looking to nature for ideas. They even have a name for this: bio-mimicry: the discovery and application of designs found in nature.
Dr. DeYoung started with the very small: Diatoms
(Look at link to see structures). These are tiny, rather geometric structures that are part animal and part plant, and they live everywhere. Why are we interested? Because scientists have found if they plate them with metal, they can use them in nanotechnology as gear and sieve parts! We can't make things this small but Nature
Did you know the Pentagon is looking to the cuttlefish, with its ability to turn on and off dyes beneath their skin, to make camouflage clothing and paint that will do the same? Or how corn's natural fiberoptics inspired the fiberoptics we use today for communication, the beech leaf's folded structure inspired the solar collectors used on satellites, or the boxfish's design was the inspiration for Mercades/Diamler Chrysler's 84 mpg European concept car
If these types of innovations interests you, check out his website that features a Design of the Month
at Discovery of Design
We are all free to believe what we wish to believe, but as our ability to observe the inner workings of cells, atoms, and systems, I believe it will take more faith to believe in evolution than in Creation or at least Intelligent Design. It is your choice. At least be open minded enough to look and consider how this could all just happen by random mutation and accident.
*I admit I am a bit of a science and medical geek, but I think it will be fascinating to many of you just the same. I was able to follow much of the video; studying homeschool biology in 2005 definitely helped!
