The major animal phyla on Earth today primarily evolved during the Cambrian Period, which lasted from about 541 to 485 million years ago. This era is marked by the "Cambrian Explosion," a rapid diversification of life forms and the appearance of many complex organisms. Most of the major animal groups we see today emerged during this time, establishing the foundational body plans that characterize modern animals.
What else can I help you with?
All of animal phyla on Earth today evolved during what period?
All animal phyla on Earth today evolved during the Cambrian Explosion, which occurred around 541 million years ago. This period marked a rapid diversification of multicellular organisms and the emergence of most major animal groups that exist today.
Were the any major events in the precambrain period?
During the Precambrian period, Earth's atmosphere and oceans were forming, and the first simple life forms like single-celled organisms appeared. There were no major events like the complex life forms and multicellular organisms evolved later during the Paleozoic era.
Almost all of the major animal body plans seen today appeared in the fossil record over 500 million years ago at the beginning of the?
Cambrian explosion. This event marked a rapid diversification of life forms and the emergence of many major animal groups. It is considered a key period in the history of life on Earth.
Would rising temperatures on earth cause major changes in plant and animal communities?
Yes, rising temperatures on earth cause major changes in plant and animal communities due to many physical changes in the environment.
Is of the major animal body plans seen today appeared in the fossil record over 500 million years ago at the beginning of what period?
The major animal body plans seen today appeared in the fossil record over 500 million years ago at the beginning of the Cambrian Period. This period is known as the Cambrian Explosion, during which a wide variety of animal forms emerged and diversified rapidly.
What important evolutionary step did the Cambrian period bring to organisms?
The Cambrian period marked the diversification of multicellular life forms, leading to the development of many major animal groups known today. This period is often referred to as the "Cambrian explosion" due to the rapid evolution of diverse body plans and the emergence of complex organisms with hard parts.
What major planet in the solar system has the longest orbital period?
Neptune, at about 165 Earth years.
What is Cambrian?
The Cambrian is a period of time which comes after the vendian millions of years before dinosaurs it was hotter than the Sahara with no plants or animals on land only in the seas.Geologists name the different periods of the earth's development. Adam Sedgwick named the period within the Paleozoic era the Cambrian period. The Cambrian period occurred millions of years ago and represents the first geological period of this era. During this time, living organisms evolved to be more complex than the formerly known single cellular types.
From Kepler's third law a hypothetical planet that is twice as far from the sun as the earth should have a period of?
Kepler's third law states that the square of the orbital period of a planet is proportional to the cube of its semi-major axis. If a hypothetical planet is twice as far from the sun as Earth, its semi-major axis would be 2 times larger. Therefore, the period of this hypothetical planet would be √(2^3) = 2.83 times longer than Earth's period.
The Cambrian period is also called the?
The Cambrian period is also called the "Cambrian explosion" due to the sudden appearance and diversification of many major animal groups.
When was the major rise in population?
When homosapians evolved.
What were the three major time periods?
Eon, era, period. Our Earth Science teacher told us to remember it as MEEP: majors eon era period. MEEP.
