What does the higher temperature do to evolution? [1]

A better air circulation through the body.

Heat protective layer on top, and on the bottom something that lets the heat of the body go, to cool down.

Needing less water, storing fat.

Burrowing.

What does less gravity mean for evolution? [2]

Taller plants.

Weaker skeleton.

Humans would become taller, the decreased gravity would not compress their spines as it does on earth.

Assuming the planet has the same atmospheric composition as Earth, the pressure would likely be decreased, making it harder to breathe.

The gravity itself would not cause evolution, however, mutations would occur in genes, e.g. more surface area of lungs. Natural selection could allow different lungs to become predominant.

ET may be a good example of a species evolving at a lower gravity field with the rotund body, duck-like flappers for feet, minimal legs, long thin arm and fingers, and a large head, large eyes, and minimal hair.

Large cloud formations, what does this mean? [3][4]

Under red dwarf stars, plant-type life on land may not be possible because photosynthesis might not generate sufficient energy from infrared light to produce the oxygen needed to block dangerous ultraviolet light from such stars at the very close orbital distances needed for a planet to be warmed enough to have liquid water on its surface

Life could eventually spread farther when such stars evolve pass their flare stage, since spectral-type M stars emit much less ultraviolet radiation once they quiet down. Until an atmospheric ozone-layer develops from oxygen gas released by early photosynthetic bacterial life such as cyanobacteria, Earth-type life may need to stay underwater to stay shield from damaging stellar ultraviolet radiation even under less active stars.

Water based clouds or CO2 based clouds?

What does a dimmer planet mean for evolution? [5][6][7]

Bigger eyes to absorb more light.

Or they can rely on other senses.

Like smell or hearing.

Echolocation.

Bioluminescence.

Plant life on this planet[8][9][10]

The Sun (spectral type G2) radiates light in a particular distribution of colors, emitting more of some colors than others. Gases in Earth's atmosphere subsequently filter that sunlight, absorbing some colors (wavelengths), and so more red light photons reach Earth's surface than blue or green ones. Not surprisingly then, photosynthetic life on Earth's land surfaces such as plants (which includes multicellular organisms from grass to trees) tends to depend mostly on red light, because it is the most abundant wavelength reaching the surface, and on blue light, because it is the most energetic. Earth plants also absorb green light, but not as strongly, so leaves look green to the eye, having adapted to the conditions most commonly found around our Sun and on Earth's planetary surface. As most stars do not have the same distribution of light in color wavelengths as our Sun, however, some researchers hypothesize that photosynthetic life on extrasolar planets will not necessarily have the same colors as on Earth.

Red light is special in that it can deliver high growth to a plant, but without the limiting effect of blue that obscures the chloroplast to protect it from high-blue midday sun. Therefore red is very efficient at producing fast growing tall and strong plants and indeed produces some of the most impressive growth rates of height and stem width in plants.

Therefore on this planet, Antilar, with a red dwarf star, which radiates most strongly at invisible infrared wavelengths and produces little blue light. By absorbing the entire spectrum of visible light more completely, such plants might look black but any color might be possible. Whatever their color, however, such plants would likely look dark to humans because little visible light would reach the ground.
