What modern cells do scientists believe to be close relatives of the Earth's first cells?
Scientists believe that modern cells called archaea are close relatives of Earth's first cells. Archaea are single-celled organisms that share similarities with the ancient cells that existed billions of years ago. Their ability to thrive in extreme environments suggests they may have characteristics similar to those of early life forms on Earth.

Where do many scientists believe modern humans appeared?
Many scientists believe that modern humans first appeared in Africa, specifically in the region of the Great Rift Valley. This is supported by fossil and genetic evidence that suggests an African origin for our species.
When do scientists believe that modern humans appeared?
Scientists believe that modern humans, or Homo sapiens, appeared in Africa around 200,000 years ago. This is based on genetic and fossil evidence that indicates the origin and migration patterns of early human populations.
What do scientists call modern humans?
Homo sapiens
What are three things modern scientists study when they classify organisms?
Modern scientists study morphology (physical characteristics), genetics (DNA and hereditary factors), and behavior when classifying organisms. These factors help determine the evolutionary relationships and taxonomic classification of different species.
That scientists still believe the cell theory today explaine why?
Scientists still believe in the cell theory because it is supported by extensive research and evidence from various fields such as cell biology, genetics, and biochemistry. The theory has been consistently validated through observations and experiments, demonstrating that all living organisms are composed of cells and that cells are the basic unit of structure and function in living beings. This foundational principle continues to shape our understanding of biology and is fundamental to many aspects of modern scientific knowledge.
Scientists believe that modern humans appeared during which epoch?
pleistocene
Scientists believe that modern humans appeared during the blank epoch?
pliocene
What do modern day scientists believe about geologic change?
It all happens suddenly
Most scientists believe modern human beings originated on which continent?
Africa
How do scientists determine the living relatives of a fossil?
Scientists use various techniques such as analyzing DNA, studying anatomical similarities, and examining geographical distributions to determine the living relatives of a fossil. By comparing these factors, scientists can infer relationships between the fossil and modern organisms to identify potential living relatives.
Where do many scientists believe modern humans appeared?
Many scientists believe that modern humans first appeared in Africa, specifically in the region of the Great Rift Valley. This is supported by fossil and genetic evidence that suggests an African origin for our species.
What continent scientists believe early modern humans came from?
Scientists believe early modern humans originated in Africa. This theory is supported by fossil and genetic evidence that suggests humans evolved in Africa before migrating to other continents.
What Scientists who agree that modern humans evolved from a single population believe that humans came from the continent of?
Africa.
During what epoch do scientists believe that modern humans appeared?
Dick
Scientists who argue that modern humans evolved from a single population believe that humans came from the continent of?
Africa.
Where were the first human reported?
If you mean where did human originate, scientists believe modern humans evolved in Africa and migrated elsewhere.
When do scientists believe that modern humans appeared?
Scientists believe that modern humans, or Homo sapiens, appeared in Africa around 200,000 years ago. This is based on genetic and fossil evidence that indicates the origin and migration patterns of early human populations.
