Archaean: Single-celled prokaryotic organisms Proterozoic: Multicellular organisms like algae and simple animals Paleozoic: Early vertebrates, ferns, and insects Mesozoic: Dinosaurs, flowering plants, and early mammals Cenozoic: Modern mammal species, birds, and angiosperms
Some organisms might have evolved features that are well-suited to their environment, allowing them to remain relatively unchanged over geological time. They may also have found a stable niche where their adaptations are successful, reducing the pressure to change. Additionally, the rate of environmental change and selection pressures in their habitat may be relatively low, limiting the need for significant evolutionary changes.
No, that isn't a statement made about evolution. The theory of evolution concerns how organisms have changed over periods of time. Everything has to have come from something! However, all living organisms alive today have evolved from predecessors, or have not really evolved much at all, e.g. Gingko bilboa and several species of sea animals.
Binomial nomenclature and phylogeny both have to do with organisms. The former refers to the modern scientist's system for naming organisms. The latter is about how an organism evolved over time.
Geological time is typically divided into units based on types of rock layers, fossils, and major events in Earth's history. The primary units of geological time are eons, eras, periods, epochs, and ages. These divisions help scientists organize and study the Earth's long history.
The answer is fossil. Fossils are the preserved remains or traces of animals, plants, and other organisms from past geological ages, which are found in rocks and sediment. Fossils provide valuable information about the history of life on Earth and how organisms have evolved over time.

Geological time provides a framework for understanding the timeline of evolution on Earth, allowing scientists to study how species have changed over millions of years. By dating fossils and rock layers, researchers can determine when specific organisms lived and how they evolved over time. This helps to build a more comprehensive picture of the history of life on Earth and the mechanisms driving evolutionary change.

Organisms on Earth have evolved and changed significantly over time.
Unanswerable.
That's correct! The theory of evolution states that organisms have evolved over time from common ancestors through the process of natural selection. This gradual change in species over generations is driven by factors such as genetic variation and environmental pressures.

No, it has changed over time. Ex) There was no oxygen when the first organisms evolved.
They evolved over time from older species.
eff the time in wich life first evolved on earth!!
