Answer:

survival of the fittest

Some die, some survive. Those that survive to reproduce pass along their genes. Some survive by good luck. Others survive because they happen to have some quality that gives them a better chance to tolerate the environmental changes. Assuming those qualities are heritable, they’ll become more common in the genes of the surviving population. Eventually they’ll predominate. The population will have adapted to the changes.

With the exception of very primitive organisms, living animals have various senses including those familiar to us as sight, sound, touch, taste, and smell. Certain organisms have senses that we do not share. For instance, the class of snakes we call “pit vipers” have a specific organ that senses heat from prey animals, even in total darkness.

Bats use echolocation, bouncing high-pitched sound waves off of obstacles and prey alike. So do dolphins.

Many insects have the ability to smell only a few molecules of pheromones from potential mate

I took the question differently than everyone else, but it sounded to me like the OP was asking for examples of HOW organisms adapt, not two organisms that adapted.

Adaptation often begins with environmental monitoring systems. Lets say antibiotics are taken by a patient and a small amount gets in the area of a pathogen who is testing its environment. The pathogen detects the threat and begins to construct a genomic edit that can counter it. Unfortunately for us, cells are still more skilled with biochemistry than humans.

If you mean like to adapt in an instant, we humans release adrenaline to overcome stress and it actually makes us more prone to overcome stress. Another example its σ32 is the heat shock sigma factor in Escherichia coli, which it helps the bacteria to survive in a “heat shock”.

When we look at evolution, we often look at bacteria or animals that aren't really related to us, like the dinosaurs and how they evolved into avian animals.

There are two examples in human history that are great for this question.

Humans

Yup. People have made adaptations to the environment. Well, at least the environment that we create for ourselves.

Milk contains lactose, which requires a special enzyme to break down. After a few months of age, babies lose this enzyme and become lactose intolerant. So why can we drink milk now?

That's because in our past, farmers began to drink milk from other an

(1) Antibiotic resistance

(2) Mitochondria losing unnecessary genes for symbiosis w/ eukaryotes

this is a miracle of evolution as we have read in our childhood about camels and about xerophytes(cactus) they got adapted to their environment but according to Darwin there is survival of the fittest which means there may be various types of a single species now under a harsh environment it may be that not all types of a single specie lives so they perish
