did they prove dark matter? There is no evidence that dark matter is capable of such a wide variety of interactions, since it seems to only interact through gravity (and possibly through some means no stronger than the weak interaction, although until dark matter is better understood, this is only speculation).
What is the cause for such extinction and what are its effects? Agriculture, forestry, mining, and urbanization have disturbed or destroyed more than half of Earth’s land area. In the U.S., for example, more than 99 percent of tall-grass prairies have been lost. Other causes of extinction today include: Exotic species introduced by humans into new habitats.
What will be the effect of species extinction in the web of life? The loss of a predator can result in what is called a trophic cascade, which is an ecological phenomenon triggered by a predator’s extinction that can also impact populations of prey, which can cause dramatic ecosystem and food web changes.

Does dark matter affect gravity?
However, dark matter betrays its presence through gravity, because every single form of mass and energy in the universe exerts some sort of gravitational influence. So the only surefire way to study dark matter is through its gravitational interactions with normal matter, such as the motions of stars inside galaxies.
What planet has extinct volcanoes?
Mars today has no active volcanoes. Much of the heat stored inside the planet when it formed has been lost, and the outer crust of Mars is too thick to allow molten rock from deep below to reach the surface. But long ago, eruptions built enormous volcanoes and piles of thick ash.
