Sonar One
How do evolutionists explain the 'irreducible complexity' of a bat's sonar?
The transmitter and the receiver both have to work very, very well for it to be useful to the bat. If a bat had one or the other parts of the mechanism that are only "part way done", it does the bat no good, and would provides no competitive advantage for survival, as I understand the theory of evolution.
For purposes of discussion, suppose it took 10,000 gradual mutations for the whole thing to work at all. After 1,000 mutations, it is still useless.
Yet, my understanding is that the earliest bat fossils are fully formed ... there aren't 'links'.
Your question is a good one, and one that many people have actively explored and continue to explore. As with any theory, it is never simple taken "on faith" but must stand up to the ongoing scrutiny of numerous scientist who would like nothing better than to disprove something so overwhelming accepted within the scientific community as evolution.
Before bat's sonar, others have raised the "complexity" issue with other examples, like the eye.
Unfortunately, I am not an expert in the field, but I remember coming across several articles and reserach on that topic. I would suggest trying a cross-reference with Scientific American magazine. I believe their have been several noted people in the field who have provided insight. I believe they list references to other published work in those articles. For example, I believe their is good evidence to suggest that evolution is not always a process of "10, 000" gradual mutations and that their is some intriguing "links" as you have described it to bat sonar that have added some depth to our understanding of evolution, but again, I'm not an expert.
I applaud you efforts to seek some rational understanding and to approach an issue like evolution that many people feel threatens some aspect of their religious faith. It seems to me that one can not truly be reverent without using the gifts that God has given us- our intelligence and curiosity to understand his creation- to stand in wonder and awe.
Good luck.
