What else can I help you with?
What era is in the First ancient life?
The Archean.
What is the first era in geologic time?
The earliest era is the Cryptic era (an informal designation) for the earliest part of the Hadean eon which is not technically seperated into era. The first formal era is the Eoarchaean.
What the era of the middle life?
The Mesozoic Era.
Era of middle life?
The Mesozoic Era.
What was the era prior to the colonial era?
The Colonial Era started with the first European Colonists to the Americas. Before that time there was very little contact between Europe and the Americas. The American continents were occupied by the Native American population.
What Era is Cambrian?
It is the era which occurred about 550 million years ago when animal life exploded onto the scene, here on planet Earth.
Life exploded for the first time?
The Big Bang theory suggests that the universe began as an extremely hot and dense state around 13.8 billion years ago. Over time, matter and energy expanded and cooled, eventually giving rise to the formation of galaxies, stars, and eventually planets where life could potentially emerge.
The first era in geologic time?
The first era in geologic time is the Precambrian era, spanning from about 4.6 billion years ago to 541 million years ago. It is characterized by the formation of the Earth, the origin of life, and the development of early single-celled organisms. This era laid the foundation for the subsequent evolution of more complex life forms.
What were the life forms in the precambrian era?
The Precambrian Era was the first emergence of complex, multicellular life forms on earth. Jellyfish and segmented worms were discovered to have lived during this time.
What era is in the First ancient life?
The Archean.
During what era did marine life become diverse?
The Paleozoic Era, because rich fossil evidence displays that early life in the time of the Paleozoic Era, there existed a dicersity of marine life.
What is the first era in geologic time?
The earliest era is the Cryptic era (an informal designation) for the earliest part of the Hadean eon which is not technically seperated into era. The first formal era is the Eoarchaean.
What era did first life appear?
Pre-Cambrian. It's when bacteria first came about.
What plants were in the Cenozoic time era?
the trees first was there
What is an fact about the paleozoic era?
There are so many facts about the Paleozoic era. This was the time when the explosion of different forms of life. New species of organisms were formed during this era which started over 500 million years ago.
Which era of geologic history marks a time when life rapidly became more complex when marine life became more diverse and plants first emerged on Earth?
The era that marks a significant increase in the complexity of life, particularly with the diversification of marine life and the emergence of plants on Earth, is the Paleozoic Era. This era began around 541 million years ago with the Cambrian Period, known for the "Cambrian Explosion," when many phyla of marine organisms rapidly evolved. The Paleozoic also saw the first land plants appear, contributing to the complexity of ecosystems.
Precombrian era what was kiving at this time?
During the Precambrian era, living organisms such as simple bacteria and algae were the primary life forms. These organisms lived in the oceans and played a crucial role in shaping the early Earth's environment. The Precambrian era is also when the first eukaryotic cells evolved, marking a significant milestone in the history of life on Earth.
