Where are the oldest organisms located in the rock layer?
The oldest organisms can generally be found in the lower layers of rock, as these layers were formed earlier than the upper layers. By examining the relative positions of different rock layers, scientists can determine the ages of the organisms found within them.
How does the position of fossils in layers show evolutionary changes?
Assuming the layers aren't deformed, the lowest deposition layers are the earliest. Later deposition layers accumulate on top of the earlier layers. Thus, the lowest layers have the earliest fossils, and the highest layers have newer fossils. By comparing the features of early and late fossils of a species, you can determine some of its evolutionary changes. Of course, not all features survive in a fossil - soft tissues, for example.
What is the term best describes data that were originally collected at the earlier time by a different person for a different purpose?
secondary data
How are the organisms on a branching tree diagram grouped?
Branching tree diagrams (or cladograms) attempt to show the ancestral relationships between species. The groupings indicate relatedness - closely grouped organisms will be more closely related (sharing a more recent common ancestor) than organisms which descend from earlier divisions, which will be further away on the cladogram.
How does anatomy and circulation differ among amniotes?
Amniotes differ from earlier vertebrates in that they can complete their life cycle on land rather than in water. Earlier vertebrates had to have water to lay eggs at the minimum. Amniotes developed eggs with amnios which allowed the eggs to be laid on land or carried by the mother.
Is evolution an abstract word?
No, evolution is not an abstract word. It refers to the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms.
What is evoluotion?
the prosses in whichdifferent types of living organisums are thought to have developed and diversified from earlier forms during the time before we existed
What physical structures were fully developed and functional in an earlier group of organisms but are reduced and unused in later species?
because they did
The branch of biology that explains both the diversity and unity of life?
The branch of biology that explains both the diversity and the unity of life is called evolution. It refers to the process by which different kinds of living organisms developed and diversified from earlier forms.
How did Christian humanism different from the earlier form of humanism that developed in Italy?
it differed from the difference just like how cool i am
What did the modern computer developed from?
Earlier computers.
How was ptolemy's different from the earlier Greek model?
Ptolemy's model is different from the earlier Greek model because Ptolemy developed a compllex geocentric model of the universe and his model seemed to explain motions until the 1500s.The early Greek astronomers believed that Earth was the center of the universe.

What is evolution definition?
Evolution is the process by which organisms change over time through genetic variations and adaptations. It involves the gradual development of new species from existing ones through natural selection and other mechanisms.
What theory states that most of Earth's current species developed from distinctly different species which existed earlier in time?
biological evolution ...........studyisland
