Iridium is rare on earth, but plentiful in meteorites. The Alvarez's suggested that a huge asteroid or comet, hit the Earth at that time. The result of such a force would be a gigantic explosion that would throw dust clouds into the sky, darkening the planet. Massive forest fires caused by the hit would also add smoke to the sky. which would then cause climate change ending the dinosaurs rein. As dinosaurs can not keep there body temp. Thats some of the evidence that i am using in my case study about dinosaurs. :-) Hope this helps xx
cell theory
The theory that the moon was formed when a large asteroid collided with the Earth, causing debris to coalesce into the moon, would be most supported. This is known as the Giant Impact Hypothesis, which suggests that the moon's irregular shape would be a result of its violent formation process.
The Alvarez hypothesis proposes that the mass extinction of dinosaurs was caused by a large asteroid impact on Earth. The impact released massive amounts of debris and dust into the atmosphere, blocking sunlight and leading to a drastic cooling effect that disrupted the global climate. This theory is widely accepted as a major factor in the extinction event that occurred about 66 million years ago.
No, it wasn't lava that killed the dinosaurs. The most widely accepted theory is that they were killed by an asteroid impact that caused a chain reaction of events, including massive wildfires, climate change, and the destruction of food sources. This event led to the extinction of most species on Earth, including the dinosaurs.
Theory suggests that it is a remnant of a large asteroid that struck the Earth
One currently accepted theory of the Moon's creation is that it was ejecta from the earth after an impact with an asteroid or comet.
It is the most accepted theory, but still a theory.

The cell theory.
The theory of evolution by natural selection. ( I assume you meant accepted )
Caralous linnaeus theory is accepted theory of speciation
The most accepted theory regarding the makeup of living things is the cell theory, which states that all living organisms are composed of one or more cells, the basic units of structure and function in organisms.
The Big Bang theory is the most widely accepted.

Nobody really knows but there are many theories. There is the mammal theory (where mammals take over) and the new plant and vegetation theory. The most famous theory is probably the asteroid collision theory.
