What is the most significant difference between the holdovers and animals in all other classes?
what's the most significant difference between the holdovers" and animals in all other classes. what's the answer.
What are the differences between the Cambrian and paleozoic fauna?
The Cambrian fauna, primarily characterized by the "Cambrian Explosion," featured a rapid diversification of life forms, including many primitive marine organisms like trilobites and early arthropods. In contrast, the Paleozoic fauna, which emerged later, included more complex and diverse life forms, such as fish, amphibians, and early reptiles, and was marked by significant evolutionary advancements. The Cambrian period laid the groundwork for the evolution of more advanced organisms seen in the subsequent Paleozoic era, which encompasses several geological periods and showcases a wider range of ecological niches. Overall, the Cambrian fauna was simpler and more primitive, while the Paleozoic fauna displayed greater complexity and ecological diversity.
Is there a difference between how the spots are located on a male or female fawn?
There is no significant difference in the pattern or location of spots between male and female fawns of the same species. Spots on fawns serve as camouflage and help them blend into their surroundings to avoid predators.
What is the difference between female and male anus?
There is no difference.
What is the difference between a male and female anus?
There is no difference.
What is the most significant difference between the precambrian and paleozoic life forms?
The Precambrian life forms were less developed than the Paleozoic life forms.
What was the biggest change in the Earth's atmosphere between the Precambrian and the Paleozoic eras?
The biggest change in the Earth's atmosphere between the Precambrian and Paleozoic eras was the increase in oxygen levels. During the Precambrian, oxygen levels were very low, but during the Paleozoic era, oxygen levels rose significantly due to the evolution of photosynthetic organisms. This increase in oxygen had a significant impact on the evolution and diversification of life on Earth.
What is the most significant difference between Precambrian and Paleozoic life-forms?
The Precambrian life forms were less developed than the Paleozoic life forms. The Precambrian life forms were just starting to develop because this was 544 million years ago. that meant that things still needed to grow. This time didn't last very long though, due to the morphic and erosional processes. The Paleozoic Era began when organisms began developing new hard parts. This made it easier for fossils to be preserved.
What is the Difference between Precambrian rocks and Paleozoic rocks?
Precambrian rocks are older than Paleozoic rocks, dating back to about 4.6 billion to 541 million years ago, while Paleozoic rocks were formed from 541 to 252 million years ago. Precambrian rocks lack fossils, while Paleozoic rocks contain abundant fossil evidence of early marine life. Additionally, Paleozoic rocks mark the beginning of complex life forms, whereas Precambrian rocks mainly consist of simpler organisms.
What was the biggest change in the earths atmosphere between the precambrian and the paleozoic eras?
The origin of free oxygen
Did scientists divide the time between Precambrian time and the present into four units or eras true or false?
False. Scientists divide the time between Precambrian time and the present into three major eras: the Paleozoic, Mesozoic, and Cenozoic eras. The Precambrian itself is a vast time period that precedes these eras and is often subdivided into eons.
When geologist divide the time between Precambrian Time and the present into three long units called?
Geologists divide the time between Precambrian Time and the present into three long units called eras: the Paleozoic, Mesozoic, and Cenozoic eras. Each era is characterized by significant geological, climatic, and biological events that shaped the Earth's history. The Paleozoic era is known for the development of early life forms, the Mesozoic era is often called the "Age of Reptiles," and the Cenozoic era is known for the rise of mammals and birds.
Why is the Canadian shield also known as the precambrian shield?
The Canadian Shield is known as the Precambrian Shield because it is made up of some of the oldest rock formations on Earth, dating back to the Precambrian Eon. These rocks were largely formed between 4.6 billion to 540 million years ago, before the Paleozoic era began.
What conspicuous difference is there between precambrian sedimentary rocks and those formed in later eras?
No fossils.
What was the first era in geological time?
The Paleozoic Era was the second in geological time. It was between 541 to 251 million years ago. Phyla, fish, arthropods reptiles and amphibians all evolved during the Paleozoic era. The end of the Paleozoic period ended with the largest mass extinction in history.
How long ago did the 'paleozoic' era begin?
That would be 251 million years ago. The end of the Paleozoic era marks the beginning of the Mesozoic. The last period of the Paleozoic era was the Permian, and the first period of the Mesozoic era was the Triassic; hence the extinction event (the biggest extinction event in the earth's history), the Permian-Triassic extinction, which defines the border between the eras.
What is a major significant difference between the sun and Jupiter?
