Okay, tell us, how is evolution useful in engineering or science?
Evolutionary algorithms are used in engineering and computer science for various purposes.
For example, NASA used such an approach when creating the antenna for the ST5 spacecraft:
Whereas the current practice of designing antennas by hand is severely limited because it is both time and labor intensive and requires a significant amount of domain knowledge, evolutionary algorithms can be used to search the design space and automatically find novel antenna designs that are more effective than would otherwise be developed. Here we present automated antenna design and optimization methods based on evolutionary algorithms. We have evolved efficient antennas for a variety of aerospace applications and here we describe one proof-of-concept study and one project that produced fight antennas that flew on NASA’s Space Technology 5 (ST5) mission.

The closing paragraph really emphasizes the power of evolutionary approaches to design:
In addition to being the first evolved hardware in space, our evolved antennas demonstrate several advantages over the conventionally designed antennas and manual design in general. The evolutionary algorithms we used were not limited to variations of previously developed antenna shapes but generated and tested thousands of completely new types of designs, many of which have unusual structures that expert antenna designers would not be likely to produce.

For biology, I always point to the field of phylogenetics (study of evolutionary relationships of organisms) as a prime example of the use of evolutionary theory within biology.
Here is a paper which mentions various applications of phylogenetics:
Phylogenetic trees have already witnessed applications in numerous practical domains, such as in conservation biology (3) (illegal whale hunting), epidemiology (5) (predictive evolution), forensics (27) (dental practice HIV transmission), gene function prediction (7) and drug development (14). Other applications of phylogenies include multiple sequence alignment (11, 25), protein structure prediction (31), gene and protein function prediction (12, 22) and drug design (30). A paper by Bader et al. (2) addresses important industrial applications of phylogenetic trees, e.g. in the area of commercial drug discovery.

And of course there were a couple patents I'd previously linked to which are examples of applied phylogenetics:
