Can evolution replace God as a watchmaker?
He concludes that evolution is a fair contestant to replace God in the role of watchmaker.

Design is top-down, someone or something more complex designs something less complex.
What is scope watch () in AngularJS?
In angularjs $watch() function is used to watch the changes of variables in $scope object. Generally the $watch() function will create internally in angularjs to handle variable changes in application.
What is scope apply?

Because we are calling into the angular framework we need to perform proper scope life-cycle of exception handling, executing watches.
What is two way binding in AngularJS?
Two-way Binding Data binding in AngularJS is the synchronization between the model and the view. When data in the model changes, the view reflects the change, and when data in the view changes, the model is updated as well.
What is $apply in AngularJS?

What is directive in Angular?

What is watcher in Angular?

Why does the argument fail in identifying that the universe is designed?
Objection 2. The Argument fails because complexity doesn’t require a designer. Another common objection is that complexity doesn’t require a designer.
Why does Paley's objection fail?
Objection 1. The Argument fails because the analogy fails.#N#This objection misses the point and thus fails because Paley’s argument is not an argument based on analogy. He’s not making an analogy between the watch and the universe. His argument is based on the identification of design. The use of a watch is just to help the reader understand why we can indentify that the watch is designed. The universe is also clearly designed. The identification of design requires a designer. Thus in identifying that the universe is designed, it is clear the universe must have a designer.
