Answer:
the trapping of the sun's warmth in a planet's lower atmosphere, due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet's surface.
Explanation:
I think it can be incorrect also so refer to Science teacher also. also.
D.
Theories always change. That's why science always changes
The lower the fossil the older it is.
So, if two fossils were in different layers of sedimentary rock, the lowest fossil is older.
The question is incomplete as it does not have the options which are:
A. The threefold change happened in one concentrated burst.
B. The change was not consistent in direction, but happened in multiple bursts concentrated at each speciation event.
C. There was consistent directional selection toward a larger brain all along the lineage between the two species.
D. None of the above.
Answer:
Option-B
Explanation:
The hominids evolved with time and the known hominid in modern time is the Homo sapiens or modern human.
The Homo sapiens like other species could have evolved from the older species through speciation and studies suggest that one of the major factors of human evolution is the size of the brain.
Two possibilities could explain the size of the brain that it could have evolved slowly with time called the gradual equilibrium or in bursts concentrated at each speciation event.
Since the punctuated equilibrium takes place in bursts until the species reach stasis is the most applicable condition for punctuated equilibrium to happen therefore Option-B is the correct answer.
I believe the process of fossilization still occurs today. The reason being why we find fossils is because of the overlaying of earth's substances over the fossil, and with the right combination, lead to fossils. It would still occur today, let's say you've buried a dog, and over time water, smelted rock, and a few other earth materials came over the dead dog's body. It would most likely be fossilized at the end of this process, but it would take years for it to happen. Fossilization does not happen in one day.
