possible explanations of the mass extinction at the end of the Triassic period
Both the article and the lecture talk about the mass extinction at the end of the Triassic period, 200 million years ago. The article strongly postulate three theories that bring possible explanations of this extinction. However, the lecture adamantly delineates each of them.
First and foremost, according to the author of the excerpt, falling down of sea levels near the end of Triassic period caused destroying of species' habitats that live in coastal regions and shallow waters. Consequently, food chains were changed inasmuch as such a mass extinction happened. Nevertheless, the professor in the lecture refuses this theory by stating that those species in that time was often encountered with fluctuating of sea levels, so because of that all of them adapted themselves to such a changing and following habitats' destruction. He states that nothing could bring such a demise only if a sudden event had occurred.
The professor in the lecture further maintains that effects of sulfur dioxide had to be in atmosphere long enough to decrease temperature, but it always combines with water and come back to the earth via rain. This claim refutes the writer implications of how sulfur dioxide could cause the very extinction.
The text lasting insists that an asteroid's colliding with the earth could be the source of this extinction because when asteroids hit the earth's surface, much debris will spread into the atmosphere all of which affects the amount of sunlight so that plants die and following many species starve. Nonetheless, the professor in the lecture opposes this theory by declaring that there is not any sign of crater back to Triassic period, so it cannot be a convincible theory.
