The morphological evidence which is shown in fossils to modern animals supports evolution because some dinosaurs, for instance, had feathers and we can obviously see that trait today in birds. The biochemical evidence, which comes in the form of DNA comparison and amino acid similarities, shows that we related closely to monkeys and pigs, which suggests that we have close ancestors to these animals.

Examples of biochemical evidence of evolution?
Physiological similarities suggest the species evolved from the same ancestor.
What is basis for evolution by natural selection?
The basis for all science, be it evolution or the study of how squeaky noises annoy people, is evidence. Darwin's primary evidence for evolution by natural selection was morphological homology; physical similarities between species. Modern evidence for evolution by natural selection is vast and includes a rich fossil record, well understood geologic evidence, radioisotopic evidence, as well as a host of genetic evidence from protein homologies to complex molecular systematics. All evidence for evolution converges on the singular observation that all organisms can be organized in a nested hierarchy much like a family tree; a Tree of Life.
What aspect of DNA is considered the strongest supporting evidence for the theory of evolution?
It's mutability and it's heritability. It changes and these changes, in the germ line, are inherited by your progeny, The change in allele frequency over time in a population of organisms; evolution.
You do not want to change though you believe in evolution?
I do not ' believe ' in evolution, but I am convinced by the evidence.
How many people believe in the theory of evolution?
When the evolutionary theory was first proposed, people didn't believe it. Often, religion and evolution contradict themselves and even today, there are many people who favor creationism over evolution.
What biochemical evidence is there supporting evolution?
One key piece of biochemical evidence supporting evolution is the similarity of genetic material across different species. For example, DNA analysis shows a high degree of similarity in the genes of humans and other primates, supporting the idea of a common ancestor. Additionally, the presence of vestigial structures and genes in organisms further supports the idea of evolution, as these features are remnants from ancestral forms.
What is the biochemical evidence that supports evolution?
DNA
What are three types of evidence of theory of evolution?
Morphological evidence.Genetic and genomic evidence.Geographical evidence.
What are the five evidence of evolution are?
biochemical evidence anatomical evidence fossils vestigial structure embryological evidence
Why is biochemical evidence of evolution considered to be indirect?
Biochemical evidence of evolution is considered indirect because it does not provide direct evidence of specific evolutionary events or transitions in the fossil record. Instead, it demonstrates similarities in molecular structures or sequences across different species, which support the idea of a common ancestor but do not directly show the process of evolution occurring.
Why do phylogenetic trees provide strong evidence of evolution?
Phylogenetic trees show how different species are related through shared ancestry, providing a visual representation of evolutionary relationships. The branching patterns in phylogenetic trees reflect the process of evolution, where species diverge from common ancestors over time. By comparing the similarities and differences in genetic and morphological traits among species, phylogenetic trees offer strong evidence supporting the theory of evolution.
Is the ancient astronaut theory true?
There is no evidence supporting it, and all the more evidence supporting the less controversial models of human evolution, based on evolutionary theory.
What is used as evidentiary support for evolution by scientists?
Evolution is the change in allele frequency over time in a population of organisms. By sequencing genes one can see this happen. Also just observing the morphological and behavioral changes in populations over time can lead to evidence supporting evolution. Check Lenski and his E. coli experiments. Over 20 years evolution was observed in these microorganisms. Fairly easy Google.
Why is biochemical evidence of evolution considered to be ibdirect?
Biochemical evidence of evolution is considered indirect because it does not provide direct observation of evolutionary changes happening over time. Instead, it relies on comparing similarities and differences in biochemistry, such as DNA sequences or protein structures, to infer evolutionary relationships among organisms.
How is the biochemical evidence of protein comparisons used in determining evolotionary history?
When the protein structure changes there has been evolution in the organism
Why are vestigial structures evidence of evolution?
Because of the morphological homologies they display with similar structures in other extant and extinct lifeforms, following, like virtually every other morphological or anatomical feature of life, the nested hierarchies of biology.
What are the four lines of evidence supporting evolution?
Genetic studies, including comparative genomics. Morphological assays in comparative morphology. Developmental studies in embryology. Palaeontology, which includes studies of the morphology of extinct species. Note that one could just as easily identify ten distinct lines of evidence, or a hundred, depending on how one classifies these lines.
