What is the Cambrian explosion why is it important to the history of life on earth?
During the Cambrian Explosion. life took a great step forward to a world called life. A great number of organisms were evolving all over the world.
During which period in the geologic time scale was there a great increase in the variety of life forms on earth?
Cambrian perod
What is mirco evolution?
micro evolution refers as evolution occurred during biochemical synthesis in primitive earth as for evolution of essential micro and bio molecules.
Where did evolution occur?
The only known instance of evolution occurring is here, on Earth. Logic dictates, however, that evolution occurs wherever there is life.
How long have invertebrates been on earth?
If you include bacteria, then about 4 billion years. (The earliest KNOWN life is 3,5 billion years old, but it had probably been around longer). If you want multicellular organisms , then about 1.2 billion years. Cambrian time period.
What is the sudden appearance of life in the fossil record called?
The sudden appearance of complex life forms in the fossil record is called the Cambrian Explosion. It refers to a relatively short period in Earth's history, around 540 million years ago, when there was a rapid diversification and emergence of diverse animal species. The Cambrian Explosion marks a significant milestone in the evolution of complex life on our planet.
What is Cambrian's Big bang?
I assume you are referring to the Cambrian Explosion... It was a period on Earth many millions of years ago after heavy bombardment from asteroids. A huge "explosion" of species and life came to form on Earth.
Whatever its ultimate cause the Cambrian explosion is a prime example of?
The sudden and very dramatic increase in life forms on earth (especially in the oceans) that took place during the Cambrian period of earth's evolution. Note that in this context "sudden" means "just a few million years".
Which era did the most animal phyla evolve?
The Cambrian era saw the rapid evolution and diversification of many animal phyla, known as the Cambrian Explosion. This era, approximately 541 to 485 million years ago, was a pivotal time in the evolution of life on Earth, leading to the emergence of a wide variety of body plans and organisms.
What is the Cambrian explosion why is it important to the history of life on earth?
During the Cambrian Explosion. life took a great step forward to a world called life. A great number of organisms were evolving all over the world.
Which event may be associated in time with the end of the period known as snowball Earth?
Cambrian Explosion
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.
When was the Cambrian period according to our geologic time scale?
People think "explosion that must have happened in a second." It didn't. The Cambrian Explosion started approximately 542 million years ago, triggered by an suddenly-oxygen-rich atmosphere and the end of glaciation, and lasted for about 12 million years. This is VERY long.
What was the earth like in the Cambrian era?
there were germs growing
What came first the ice age or Cambrian explosion?
The so-called "Cambrian Explosion" was more than 500 million years ago. About 700 million years ago there was possibly a very big ice age which covered most of the earth for a very long time. The latest ice age is the one we are in now which started only about 2.6 million years ago and has been composed of periodic glaciations interspersed with warmer times such as now. The last glaciation ended about 10,000 years ago depending on where on earth you live.
What is the name of the earth evoulution of Eevee?
there is no earth evolution of eevee retards there is no earth evolution of eevee retards there is no earth evolution of eevee retards there is no earth evolution of eevee retards there is no earth evolution of eevee retards there is no earth evolution of eevee retards
According to the fossil record how many years ago did life first seem to appear on Earth?
The Cambrian Explosion, a period between about 540 and 530 million years ago when many major animal groups appeared in the fossil record. This is when animals first developed hard shells and skeletons, so they became much more easily fossilised. Nobody is quite sure what caused the Cambrian Explosion, but increased oxygen levels in the air after the melting of a huge ice age around 600 million years ago may have led to an increase in the size of animals in the oceans; in turn they developed skeletons and shells to support their larger bodies. The evolution of predators may have inspired prey animals to develop shells, as well. We do have fossils before the Cambrian Explosion, but these are simple, soft-bodied, small and rare, so the origins of animals are still shrouded in mystery.
