With the nested hierarchy of phylogenetic trees in front of you, showing in general relief the biochemical, physiological, behavioral relatedness extended from the forked nodes, and going along through time one sees evolution in action. Change over time.
DNA and protein sequence similarities among different species provide strong molecular evidence for evolution. Mutations in DNA that accumulate over time can be used to construct phylogenetic trees, showing the relatedness between different species. Comparative genomics also reveals shared genetic elements and patterns of gene expression that support the concept of common ancestry.
The primary evidence supporting evolution comes from a combination of fossil records, comparative anatomy, embryology, molecular biology, and observed genetic changes over time. These pieces of evidence collectively provide a strong foundation for the theory of evolution.
Evidence supporting the theory of evolution comes from various fields, including genetics (DNA similarities between species), paleontology (fossil record showing transitional species), embryology (similarities in early stages of development), and biogeography (distribution of species across different regions). These studies collectively provide strong evidence for the process of evolution by natural selection.
Molecular genetics
Yes, there is. That is why scientists refer to it as a theory, and not just a hypothesis.Various claims are made by critics of evolution; all of these are based on misapplied science and misinterpretation of facts, coupled with bad logic. Competing claims are made using "evidence" from the Bible, which as a religious document, has no application to biological study.

There is strong support for the theory of evolution due to fossils that have been found by archeologists. The fossil records show evidence of evolution over billions of years.
Yes, there is strong phylogenetic evidence suggesting that all dromaeosaurids possessed them. This evidence comes from phylogenetic bracketing, which allows paleontologists to infer traits that exist in a clade based on the existence of that trait in a more basal form. In other words, evidence of raptors having feathers has been found in the bones themselves as well as fossil prints.

Molecular genetics
Phylogenetic hypotheses are strongest when they are supported by multiple lines of evidence, such as morphology, genetics, and fossil data. Additionally, hypotheses that are consistent with principles of evolutionary theory and show high levels of statistical support are considered strong.

Scientists use various types of evidence to support evolution, including fossil records showing transitional forms, the distribution of species around the world, comparative anatomy and embryology, genetic similarities among organisms, and observed instances of natural selection. These different lines of evidence provide a strong basis for understanding the process of evolution.
Fossil evidence of evolution is not typically disproved, as fossils are considered crucial pieces of evidence in supporting the theory of evolution. However, the interpretation of fossil evidence can sometimes be open to debate or revision based on new discoveries or scientific understanding. Overall, the accumulation of diverse fossil evidence provides strong support for the concept of evolution and the relatedness of different species.
Fossil record shows a progression of organisms from simple to complex forms over time. Comparative anatomy reveals similarities in bone structure and development between different species, indicating a common evolutionary ancestry. Genetic similarity and shared sequences in DNA among different species provide strong evidence for common ancestry and evolution.
Paleontology, genetics, molecular Biology, taxonomy, evolutionary development and comparative anatomy, just to name a few.
