Natural selection in the cichlids fish species of Lake Victoria occurred via

Where's the evolution?

The physics of light affects not just how blue water looks to us, but how the animals living in the world's oceans, lakes, and rivers are able to find food and each other — and this, in turn, can impact their evolution. Natural selection favors traits that perform well in local environmental conditions. Many fish species, for example, have evolved vision that is specifically tuned to see well in the sort of light available where they live. But even beyond simple adaptation, the physics of light can lead to speciation. In fact, biologists recently demonstrated that the light penetrating to different depths of Africa's Lake Victoria seems to have played a role in promoting a massive evolutionary radiation. More than 500 species of often brightly colored cichlid fish have evolved there in just a few hundred thousand years!

Detailed records of change within individual species show that although characters commonly remain relatively unchanged for long
Evgen [1.6K]
It is consistent with Punctuated equilibrium. A theory that states that when a species show up in the fossil record they will turn into a stable record, showing almost zero evolutionary change through their geological history. When the species do change, this change is rapid and split the species into tow rather than make the original species evolve into another one.

What happens to the amount of light as you go deeper into aquatic system
gavmur [86]

Light bends when it hits water so it can only travel so far. So the deeper you go the less light there will be.

Explanation:

The ocean is broken into three zones based on intensity and light level. The upper 200 meters (656 feet) of the ocean is called the euphotic, or "sunlight," zone. This zone includes the vast preponderance of commercial fisheries and is home to many preserved marine mammals and sea turtles.Only a small amount of light penetrates behind this depth.The zone between 200 meters (656 feet) and 1,000 meters (3,280 feet) is usually regarded to as the “Twilight” zone, but is authorized the dysphotic zone. In this zone, the intensity of light rapidly consumes as depth increases. Such a miniscule amount of light penetrates beyond a depth of 200 meters that photosynthesis is no eternal possible.The aphotic, or “midnight,” zone survives in depths below 1,000 meters (3,280 feet). Sunlight does not perceive to these depths and the zone is immersed in darkness.
