From the article linked below we can know that odometry is the process of distance measurement. This is important to the tarantula because it uses "path integration to return to its burrow". What is interesting is that "it does not follow the same path back to its burrow; instead, it moves as though it had followed the sides of a right-angle triangle, returning along the hypotenuse". This article discusses how each of the four pairs of eyes of the spider impacts its ability to navigate.
Intelligent Design or Unintelligent Design?
Once again we see another example of sophisticated design in a living creature. In this case, navigation. The question is if this is an example of intelligent design or unintelligent design. Let's ignore the fact that unintelligent design is a contradiction to the concept of design in general. By definition, if something is designed, it must have been so intelligently. Remember that the capability of the spider's navigation is a result of the programming in the DNA. The ability of random mutations to create such complexity is not possible as mutations are observed to destroy and degrade, not build and design. Once again, more observable evidence for a creator, who is Very good at engineering!
