What else can I help you with?
What are traces or remains of organisms that lived in the past?
Fossils are proof of organisms that lived long ago
What are the preserved remains of living organisms arranged by age?
Fossils are the preserved remains of living organisms arranged by age in the Earth's layers. They provide evidence of past life forms and help scientists understand the history of life on Earth through the process of fossilization. By studying fossils, researchers can reconstruct the evolutionary relationships and environmental conditions of ancient organisms.
What is the theme in biology that helps understand how organisms are related to other living organisms and to organisms that are close in the past?
evolution
Were there living things on mars?
There is no definitive evidence of current life on Mars. However, scientists have found evidence that suggests Mars may have had conditions conducive to supporting microbial life in the past. Ongoing research and exploration continue to search for signs of past or present life on Mars.
Which cell organelles provide strong evidence for endosymbiotic origination?
Chloroplasts and mitochondria provide strong evidence for endosymbiotic origination. Both have their own DNA, double membranes, and replicate independently of the cell, indicating they were once free-living prokaryotic organisms that were engulfed by a host cell in the past.
How do fossils provide evidence that species alive today have evolved from simpler organisms?
Fossils provide evidence of evolution by showing a record of past life forms, demonstrating the gradual changes in species over time. By examining the fossil record, scientists can trace the lineage of modern species back to simpler, ancestral forms. Transitional fossils, which exhibit characteristics of both older and newer species, further support the idea of evolution by showing the gradual changes that occurred over generations. Overall, fossils provide tangible evidence of the process of evolution and the interconnectedness of all living organisms.
What kind of evidence from evolution best supports all the others?
The evidence from the fossil record is considered the strongest support for other forms of evidence in evolution. Fossils provide a physical record of past organisms, showing changes over time and the relationships between different species. This evidence complements genetic, anatomical, and embryological evidence to provide a comprehensive understanding of evolutionary processes.
Fossils tell how earths land blank blank and living things have changed over time fill in the blank.?
Fossils tell how Earth's landforms, climate, and ecosystems have changed over time. They provide valuable clues about the past by preserving evidence of ancient organisms and environments.
Preserved remains or traces of living things?
Fossils are preserved remains or traces of living things that provide evidence of past life on Earth. These can include bones, teeth, shells, tracks, and imprints of organisms from millions of years ago. Studying fossils helps scientists understand the history of life and how species have evolved over time.
Evidence of the activity of organisms in the past is called a?
Fossil. Fossils are the preserved remains or traces of ancient organisms that lived in the past, providing valuable insights into the history of life on Earth.
What was the preserved remains of ancient organisms called?
The preserved remains of animals of evidence of their existence are Fossils Fosssils that provide evidence about the past are called trace fossils.
Is the fossil record valid evidence for evolution?
Yes, the fossil record is considered a valid and significant piece of evidence for evolution. Fossils provide a record of past life forms and show a progression of species over time, supporting the idea that organisms have changed and diversified through evolutionary processes. Additionally, the discovery of transitional fossils helps to fill in gaps and provide connections between different groups of organisms.
