Geological evidence refers to physical evidence found in rocks, minerals, landforms, and fossils that provide insights into Earth's history, past environments, and processes. This evidence helps scientists understand how the Earth has evolved over time and provides clues about past climate, tectonic events, and life on Earth.
Two types of structural evidence are physical evidence (such as fibers, fingerprints, and DNA) and trace evidence (such as soil, glass fragments, and hair). These types of evidence can help investigators reconstruct events or link a suspect to a crime scene.
== == Homologous provide evidence for evolution because it shows the similarities and how we evolved from the same ancestors
Scientists believe birds evolved from dinosaurs because of several pieces of evidence, such as shared skeletal features, fossil records of "transitional" bird-like dinosaurs, and genetic similarities. These connections suggest that birds are the descendants of a group of small theropod dinosaurs.
One piece of evidence supporting the idea that poriferans evolved from protists is the similarity in genetic sequences between certain protists and sponges. Additionally, some protists share characteristics with poriferans, such as the presence of collar cells, which suggests a possible evolutionary relationship between the two groups. Studies of early fossil records also provide some evidence of a transitional form between protists and sponges.
The process of radiometric dating provides some of the best evidence that Earth has evolved over geologic time. By measuring the decay of radioactive isotopes in rocks and minerals, scientists can determine the absolute age of geological materials, helping to establish a timeline of Earth's history.
Embryology provides evidence for evolution by showing similarities in the early stages of development among different species, suggesting a common ancestry. This supports the idea that organisms have evolved from a shared ancestor over time.
DNA is used as evidence to support the theory of evolution by comparing the genetic similarities and differences between different species. By analyzing the DNA sequences of organisms, scientists can trace evolutionary relationships and determine how species have evolved over time. This genetic evidence provides strong support for the idea that all living things are related and have evolved from a common ancestor.

Scientists use fossil evidence to prove the existence of organisms that lived in the past, how life has evolved over time, the environmental conditions of ancient ecosystems, and the relationships between different species. Fossils provide valuable information about the history of life on Earth and help scientists reconstruct evolutionary pathways.
DNA evidence is crucial in modern evolutionary theory as it provides a molecular blueprint of how species are related. By comparing DNA sequences among different organisms, scientists can trace their evolutionary history, identify genetic variations, and infer how species have evolved over time. This evidence helps support the idea of common ancestry and provides insights into the mechanisms of evolution.
They evolved over time from older species.
Because humans and birds are two completely different organisms and they have evolved along different evolutionary pathways.
Segmentation is present in both groups.
Theory of evolution
Many scientists have said so based on the evidence they found.
Mitochondria and chloroplasts have their own DNA.
