Debris (Hydrogen and helium) from the big bang gravitationally clumped together, and frequently these clumps got big enough to start fusion in their centers and form stars.
What is big bang theory?
The Big Bang theory explains how the cosmos expanded from a highly dense and hot starting condition. The evolution of the observable cosmos from the earliest known times up to its later large-scale shape is explained by this prevalent cosmological model. A wide range of observable phenomena, such as the quantity of light elements, the cosmic microwave background (CMB) radiation, and large-scale structure, are all thoroughly explained by the model.
Eventually, the large gaseous balls fuse hydrogen into heavier elements, which causes them to become stars. The periodic table's iron is created when stars combine light elements to create heavier ones.
The remaining elements of the periodic table are created as a result of the stars exploding, producing white dwarfs that explode, or forming neutron stars that collide and explode. The remaining hydrogen gas is now "contaminated" by this other material, and some of it forms an accretion disk in which planets form when it compresses under gravity.

I'll choose Golden Retrievers:
These dogs where created for duck-hunters. Their purpose was to go catch the ducks that fell on the lake/river once they were shot by the hunter - here we see how they serve (or actually served) men.
Nowadays, Golden Retrievers are known to like water a lot, and to be very playful with it - and here is where we see a genetic adaptation. They needed to be in water, and were modified to like it.
