The comparisons between the anatomies of various organisms show common ancestry which supports evolution.
The evidence for animal and human evolution is so overwhelming that it is not possible to list it all within the scope of a short .Following decades of research, Charles Darwin published his book, The Evolution of Species in 1859. This contains copious evidence for evolution by natural selection, yet Darwin barely touched on the wealth of detail that we now have on evolution.Darwin, writing at a time when the known fossil record was scanty, barely touched on what we now know. We now have an extensive fossil record of the evolution of numerous species, with intermediate forms showing how one species or genus has gradually evolved into others.A good scientific theory should be able to predict facts that we do not yet know. The discoverers of Tiktaalik Roseaebelieved that the Theory of Evolution predicted that a species intermediate between fish and amphibians should be discovered in specific rock layers of a proposed search area, went there and soon found what they were looking for.Recent advances in our knowledge of DNA now mean that we have another scientific basis for animal evolution. For example, scientists can use DNA evidence to ascertain that our human ancestors diverged from the ancestors of the chimpanzee some seven million years ago. That this seems consistent with the dossil record should not be regarded as a mere coincidence.
Comparative anatomy and evolutionary development have shown the connection between species; both the near and far connections. Look at the bones in your arm and then at the foreleg bones of your cat or dog and see how evolutionarily close the both of you are. The HOX genes between you and fruit flies, the control genes for making bodies, show that you and flies share common ancestry as suggested by evolution.
Individuals in a species show variation, which is a key concept in Darwin's theory of evolution. This variation can arise from genetic differences or environmental influences, and it provides the raw material for natural selection to act upon, leading to the evolution of species over time.
Inference (deduction) is the process of determining a conclusion based on given evidence. Since we often can't know precisely what a prehistoric animal or plant looked like (unless it was completely preserved, as is the case with ice or amber), we have to take what bones, casts, molds, etc. that exist, and infer something about the plant or animal based on the structure and surroundings. For example, based on what we know about structure and function of various anatomies of existing animals, we can infer things about dinosaurs based on the bone structures found in their fossils. We can also determine whether they were predators or prey, whether they hunted or traveled in herds, in what class of animal we can group them, and so forth.
== == Homologous provide evidence for evolution because it shows the similarities and how we evolved from the same ancestors
Homologous structures in evolution refer to features that have a similar underlying structure, indicating a shared ancestry despite potentially different functions in different species. These structures are thought to have evolved from a common ancestor and provide important evidence for the theory of evolution. Examples include the pentadactyl limb structure in vertebrates and the similar bone structure in the wings of birds and the limbs of mammals.
They show similarities between organisms structure. if the similarities are large then it shows that those organisms share a common ancestor.
The fossil record shows transitional forms that link present-day species with their ancestors, providing evidence of evolutionary change over time. Geographic distribution can reveal patterns of related species in different regions due to their common ancestry and evolution in separate environments. Homologous structures across different species share a common anatomical origin, indicating a shared evolutionary history. Vestigial structures are remnants of once-functional traits that have lost their original purpose, reflecting an ancestral trait retained through evolution. Embryology can show similarities in the early stages of development among diverse species, reflecting their shared ancestry and evolutionary relationships.
The presence of homologous structures (for example, the bone structure in chimpanzee arms, human arms, and whale flippers) indicates that the species sharing that homologous structure share a common ancestor.
Morphological divergence refers to how different species evolve distinct physical characteristics over time. Homologous structures are similar traits found in different species due to a common ancestor. In essence, morphological divergence can lead to differences in body structures, while homologous structures show similarities in body parts across species.
DNA can provide evidence of evolution through the presence of homologous genes, which are genes shared among different species that originated from a common ancestor. Additionally, the similarity of DNA sequences between related species can show how closely they are related evolutionarily. Mutations in DNA can also accumulate over time, leading to genetic variation that drives evolutionary change.
The panda's thumb does not show evidence of design, good or bad. It shows evidence of evolution.
Oh, dude, like, you can compare the DNA of different organisms to see how similar they are genetically, which can show their evolutionary relationships. And, like, you can also look at their physical characteristics and see how they're similar or different, which can also give clues about their shared ancestry. It's basically like playing a genetic detective game, but with, like, way less action and more lab coats.
Fossils can be used as evidence for evolution because they can show the development of a species over a long period of time.
homologous structures- same structure/different functions in common ancestors analogous structures-same functions/differnt structures not in common ancestors vestigial-show evolutionary history/structures that arent used anymore (i.e. human appendix/human tailbone)
Evidence for evolution includes the fossil record showing transitional forms, comparative anatomy showing similarities in structures among different species, genetic similarities among different species, and observed instances of natural selection leading to changes in populations over time.
