Killifish are a way to study evolution. They are unique in that you can tell how DNA works, and then use those principles, to in the future determine other rules of evolution for other animals/species.
These fish act as a mirror, reflecting their environment, telling us details about heir surrounding area, animals that live nearby, plants nearby, the temperature of the water, whether it has lots of minerals or none.
Most importantly, by looking at these details we can piece totgerther how they have changed overtime, and understand evolution better.
In turn we apply these things we learned about evolution to the surrounding environment, plant and animals.
A simple example is showing how the landscape has changed. Geographic areas changing int he past can determien how they will change in the future. Even how they are changing right now.
A river over time changes into 2 or 3 different rivers, some may conenc to the original, some may beceome cut off fromt he original. These changes affect all the species habiting the rivers. And this can determine how they evolve.
We must have a thorough understanding of al the physical parameters. This is where physics and science come in. Soils must be tested for containing elements, types of rock, and minerals, all which determine how fish evolve.
Example, most African freshwater fish are more colourful than South American freshwater fish because the African soil has a greater amount of minerals int eh soil.
Similar to how cadmium makes yellow, orange and red paint. Or iron can make green and blue paint. Well these minerals can make fish have more vibrant yellow, red, green and blue.
