Bat’s tree identification copied, according to an article in SciencNOW and PLOS Computational Biology 21 Mar 2008. Bats are well known for being able to find their way around and avoid obstacles using echo-location, i.e. by sending out bursts of sound and analysing the echoes. They can also use the echoes to identify different kinds of trees, even in densely wooded areas. A group of German scientists have recently invented a computerised system to do the same. Researchers bounced sonar signals off five different kinds of trees and bushes and analysed the reflection patterns. They then developed data sets called “spectrograms” which enabled them to identify each type of plant with near 100 per cent accuracy. The scientists are hoping their computer algorithms could be used to make more accurate remote sensing systems.
Editorial Comment: As the computer engineers who designed the system acknowledge, they copied the method of echo-identification from the bat rather than inventing it themselves. Therefore, the fact that it takes a computer, a machine designed and built by creative engineers, and a computer program, the product of a mind, to analyse echoes and make use of them, is evidence that the bat’s brain also was created and programmed by a much smarter engineer. Sadly such evolutionists have no excuse for refusing to believe in the Creator and give Him the glory for inventing the system. (Ref. sonar, computing, chiropterans)
