Answer: yes I do believe the break up of peagaea had to do with the mass extinctions of some dinosaurs in such as the environment had changed for some and they weren’t able to cope it, it can also be the lack of food sources and predators. However with the Pangea there were new species of dinosaurs that had evolved which gave them a better survival then the first generations of dinosaurs when peangea was just started to appear
Explanation:
It is assumed that the context of the hypothesis request is related to the origin of life, OoL, Volcanoes emit gases, dust and minerals at elevated temperatures that produce movement and chemical interaction of minerals, water, gases and compounds emitted. These minerals, water, and gas are considered important to produce the biochemical assembly of compounds into molecules for the OoL.The volcanic thermal energy release is a key ingredient in stimulating chemical reactions as well as dissipating the chemicals and gases, some of which was considered to have deposited in small ponds, based on Darwinian mythology in amounts and concentrations conducive to biochemical assembly capable of OoL production..
In the atmosphere volcanic emissions have been considered possibly viable to support the Oparin-Haldane theory, which proposed the emission of biochemically rich gases that utilized volcanic, solar and atmospheric energy sources to precipitate biochemical molecules that led to a prebiotic soup of compounds that eventually led to the OoL.
The main difference between mammalian and reptilian teeth is that reptiles are usually homodont while mammals are typically heterodont. This means that all reptiles’ teeth are the same shape and on the other hand, mammals have different types of teeth, like incisors, canines, premolars, and molars. The advantage of mammalian teeth is in those difference in size and shape of teeth which results in their different function. Thus, mammalians are more efficient and specialized for different types of feeding.
I believe your answer would be Echinoderms and Chordates. I hope this helps!
