Neutrophil Chemotaxis

http://www.FreeScienceLectures.com

Human neutrophils are mobile cells that will quickly migrate to sites of injury to help fight infection. They are attracted there by chemical signals released by other cells of the immune system or by invading microbes.

In this experiment substance is released from micropipette that makes the neutrophils polarize and move towards that location.

"im just skeptic about evolution because its such a big step from making a theory and presenting something as fact."

Someone fell asleep during science class. You're confusing the term 'theory' with 'hypotheses.' A theory is something that unifies & explains a series of established facts. Evolution is fact in that it occurs, and we use the theory to explain how it occurs.

The sad fact is that creationists like you fail to comprehend science at even the most basic level.

Neutrophil are people too ! :-)

SO COOL. SCIENCE AND NERDS ARE BEST.

Evolution by natural selection is not a process which brings rise to life, but one which simply changes its nature (often making it more complex - but only where this is advantageous). There are many theories as to the origins of life, but these remain only as theories while the evidence for evolution by natural selection is irrefutable.

@Ultrasecond -

Order does not come from disorder and evolution violates the Law of Biogensis - Life comes from Life. If any scientist can produce Life from non-life I am intersested otherwise Evolution remains a theory. Maybe you should read Darwin talking about the need for plants as well as animals to have evolved and he could not find evidence for plant evolution.

Fascinating, I'm just wondering if this is in real time or not... it seems unlikely that they move so fast...

I have low Neutrophil levels I guess I am screwed :(

@sKilfoyProdCo especially people with advanced education in the medical field. Human physiology is so amazing and complex. I love studying it.

@luck2308 ... As a man of religion and science, I see this all the time. I can't speak for ultrasecond's situation, but in my observations, scientists tend to understand religion at a deeper level than religionists understand science.

@Ultrasecond

People who undermine religion are doing exactly the same thing they don't like religionists to do: consider other people's belief inferior than yours.

Ultrasecond, the sad fact is that you fail to comprehend religion and other people's views at even the most basic level. Open your eyes, mate.
