what may cause a species to become extinct? The main modern causes of extinction are the loss and degradation of habitat (mainly deforestation), over exploitation (hunting, overfishing), invasive species, climate change, and nitrogen pollution.
How does extinction lead to evolution? Many species have gone extinct throughout history and all that marks their presence on Earth are fossils, such as this one of a dinogorgon. When a species disappears, biologists say that the species has become extinct. By making room for new species, extinction helps drive the evolution of life.
How might extinctions affect the evolution of organisms that survive the event? In effect, a mass extinction cleans the slate, creating new evolutionary niches which promote a wide range of species, increasing biodiversity, competition and in some cases increasing complexity in organisms as they try to carve out their niche in the new world. We are an example of the aftermath of mass extinctions.
How does extinction affect ecosystems? As species go extinct, they are taken out of the food chain. Animals that ate the newly-extinct species have to find new food sources or starve. This can damage the populations of other plants or animals. Furthermore, if a predator goes extinct, its prey’s population can proliferate, unbalancing local ecosystems.

There have been five mass extinction events in Earth’s history: ‘The Big Five’. More than 178 of the world’s largest species went extinct during the Quaternary Extinction. Overhunting was likely the main driver. Extinction rates today are much higher than background rates and rates from previous mass extinctions.

Will there be redheads in 100 years?

What made Megalodons go extinct?
Fossil evidence suggests that megalodons went extinct before about 2.6 million years ago, during a period of cooling and drying in many parts of the world. These changes may have been related to the closing of the seaways separating North from South America and Eurasia from Africa.

What could dark energy be used for?
Dark Energy is a hypothetical form of energy that exerts a negative, repulsive pressure, behaving like the opposite of gravity. It has been hypothesised to account for the observational properties of distant type Ia supernovae, which show the universe going through an accelerated period of expansion.
Is dark matter attracted to mass?
All particles of matter are attracted to each other through the force of gravity. Dark matter seems to be the “glue” holding galaxies together with all their ordinary matter, for the mass of ordinary matter alone is not enough. Galaxies would fly apart if not for the extra, dark mass.
