Evolution is the physical change of heritable traits over a series of generations. An example of this would be the theory of Humans evolving from Apes.
Consider only the stars Betelgeuse, Bellatrix, Polaris, and the sun. based on their mass, Bellatrix star is most likely to turn into a black hole first
A main sequence star with the stellar designation B2 V, Bellatrix is bluish in color. It has a giant-like spectrum, which is why a number of sources refer to its B2 III spectral type. The star is still a hydrogen-fusing dwarf, according to both the Simbad and NED databases, which both have the spectral type B2 V.
Bellatrix has a radius of 5.75 times the solar radius and an 8.6 times solar mass. It shines with 9,211 solar luminosities and an effective surface temperature of 21,700 K. It won't be long before the star, Bellatrix is thought to be 25.2 million years old, exhausts its hydrogen fuel, transforms into a subgiant, and then into an orange giant.
