It is known that the Earth's orbit around the sun changes shape every 100,000 years. The orbit becomes either more round or more elliptical at these intervals. The shape of the orbit is known as its "eccentricity." A related aspect is the 41,000-year cycle in the tilt of theEarth's axis.
In simpler terms, the Big Bang theory says the universe as we know it started with a small singularity, then inflated over the next 13.8 billion years to the cosmos that we know today. In the first second after the universe began, the surrounding temperature was about 10 billion degrees Fahrenheit (5.5 billion Celsius). The cosmos contained a vast array of fundamental particles such as neutrons, electrons and protons. These decayed or combined as the universe got cooler. Over time, however, the free electrons met up with nuclei and created neutral atoms. This allowed light to shine through about 380,000 years after the Big Bang.

Answer: 3- mutation, natural selection, migration
Explanation:
1-genetic drift, mutation, natural selection
2-mutation, founder principle, bottleneck effect
3-mutation, natural selection, migration (gene flow)
The correct answer for this question is" #3.mutation, natural selection, migration (gene flow)." The sequence of evolutionary mechanisms which have come into effect in each event is that of mutation, natural selection and migration. There is a steady rise in the population of bright-colored fish. Both populations thrive.
