Humans share around 99.9 percent of their DNA after all we all are humans and only a small amount is what makes you, you.
Chimpanzees are 97% similar to humans. Cats have 90% of homologous genes with humans, 82% with dogs, 80% with cows, 69% with rats and 75% of mouse genes have equivalents in humans. And about 60% of chicken genes correspond to a similar human genes

Is evidence to support the idea that two different species might have a common ancestor?
Yes, evidence supporting the common ancestry between two different species includes similarities in genetic sequences, anatomical structures, and developmental patterns. Additionally, the fossil record often reveals transitional forms that link different species together. Overall, these lines of evidence strongly support the theory of evolution and common ancestry among living organisms.
What does the biogeography or fossils support evolutionary theory?
Biogeography, which studies the distribution of species, supports evolutionary theory by showing patterns of species distribution that align with the idea of common ancestry and evolution. Fossils provide physical evidence of species that have existed in the past, showing transitional forms and demonstrating the gradual changes in organisms over time, supporting the concept of descent with modification proposed by evolutionary theory.
Does the existence of intermediate forms support or not support the theory of evolution?
The existence of intermediate forms supports the theory of evolution. These transitional forms provide evidence of how species have evolved over time through gradual changes and adaptations. They demonstrate the idea of common ancestry and the gradual development of new species from ancestral ones.
How do the lines of evidence support the theory of evolution?
The lines of evidence that support the theory of evolution include fossil records, comparative anatomy, molecular biology, and biogeography. Fossil records show a progression of life forms over time, while comparative anatomy reveals similarities in structures among different species. Molecular biology demonstrates common genetic sequences among organisms, and biogeography examines the distribution of species around the world, all of which provide evidence for the common ancestry and gradual change of species over time outlined in the theory of evolution.
What is the common ancestry theory?
The common ancestry theory proposes that all living organisms on Earth share a common ancestor. This idea is supported by evidence from evolutionary biology, genetics, and the fossil record, showing similarities in the genetic code and biological structures across different species. It underpins the understanding of evolutionary relationships between organisms and the diversity of life on our planet.

Additionally, the fossil record often reveals transitional forms that link different species together. Overall, these lines of evidence strongly support the theory of evolution and common ancestry among living organisms.
Which biologist first proposed that all organisms share a common ancestry?
Charles Darwin, in his seminal work "On the Origin of Species" published in 1859, proposed the theory of evolution by natural selection, suggesting that all life on Earth shares a common ancestry.

How does anatomy support the theory of evolution?
Compare the bones in your forearm with the bones in the foreleg of your cat or dog and know that you and all mammals share common ancestry.
What evidence support evolutionary theory?
Fossils depict gradual changes in species over geologic time. This was one primary bit of evidence for Darwin's theory. Another was the similarity in species separated by geography. Race circles are one example of this. Variations introduced by pigeon breeders demonstrated that variations resulted in inheritable traits. Today we also have DNA, which clearly demonstrates common ancestry between species.
What is the common ancestry theory?

How does comparing anatomy support the theory of evolution?
Compare the bones in your forearm with the bones in the foreleg of your cat or dog and know that you and all mammals share common ancestry.
How does embryology provide evidence in support of the theory of evolution?
Embryology provides evidence for evolution by showing similarities in the early stages of development among different species. This suggests a common ancestry and supports the idea that organisms have evolved from a shared ancestor over time.
What 2 biochemical compounds support the idea things evolved from common ancestors?
Two biochemical compounds that support the idea of evolution from common ancestors are cytochrome c and hemoglobin. These compounds exhibit significant sequence similarities across a wide range of species, suggesting a common ancestry. The variations in these compounds also align with the evolutionary relationships predicted by the theory of common descent.
What are 3 steps of biological evidence that provides the basis for the theory of evolution?
Fossil record: Shows a pattern of gradual change in species over time, supporting the idea of common ancestry and evolution. Comparative anatomy: Similarities in bone structure and body plans among different species suggest they share a common evolutionary history. DNA evidence: Genetic similarities between different species reveal evolutionary relationships and provide strong support for the theory of evolution.
