Answer:
Direct observation of evolutionary change: creation of drug-resistant bacteria.
Fossil record: discovery of transitional forms of animals, discovery of shells of extinct organisms
Homology: similarities in mammalian forelimbs, identical genetic code in fireflies and tobacco plants, vestigial pelvis in right whales
Biogeography: resemblance of endangered island species to neighboring mainland species,
When analyzing data scientists look for patterns, that help them form predictions.
Patterns are rules that variations/characteristics follow, either in data or anything else patterns might be used for.
Example:
The fact that worms are found always 10 meters forom eachother (not true, it's an example) is a pattern, that will help you predict the location of the next worm.
