Which model of evolution shows change over a relatively short period of time

fossil evidence is when scientist study fossils to figure out how the animal died how it evoled
There is plenty of fossil records and observable speciation to provide evidence for Evolution. Within the scientific community there is little to no debate on whether evolution is wrong. No concrete evidence has been provided by anyone to dispute the claims of evolution since its formulation by Darwin, otherwise it would have been discarded through the scientific method.--------------------------------------------------------------------------------------------While the above is right, observation and scientific studies provide evidence and arguments to the theory.
Structures which are apparently different and performing different functions but their basic structure is similar are called homologous structures and indicate common ancestry eg. fore limbs of bat , whale , horse dog and man apparently different but are made up of humerus , radius , ulna , carpel , metacarpals and phalanges .
Since the wings of insects and birds have different structures (or different designs) but perform similar functions, they are analogous organs. Now, since the analogous organs have different basic design, so they do not indicate a common ancestor for the organism. The analogous organs provide evidence for the evolution in another way. The presence of analogous organs indicates that even the organisms having organs with different structures can adapt to perform similar functions for their survival under hostile environmental conditions. Thus, the presence of analogous organs in different animals provide evidence for evolution by telling us that though they are not derived from common ancestors, they can still evolve to perform similar functions to survive, flourish and keep on evolving in the prevailing environment. The analogous organs actually provide a mechanism for evolution.
Vestigial structures are considered critical evidence of evolution because they are remnants of organs or structures that have lost their original function through the process of evolution. These structures provide insights into an organism's evolutionary history and support the idea that species have changed over time. The presence of vestigial structures suggests that organisms have inherited traits from their ancestors, even if those traits are no longer useful.

Vestigial structures are anatomical features that have lost their original function in an organism but are still present. These structures often have similarities to functional structures in related organisms, suggesting a shared evolutionary history. By studying these vestigial structures, scientists can infer how organisms have changed over time through the process of evolution.
The existence of vestigial structures is significant to the study of evolution because they provide evidence of an organism's ancestral lineage and indicate how species have adapted over time. These structures, which have lost their original function, suggest that evolutionary processes lead to changes in anatomy and functionality in response to environmental pressures. By studying these remnants, scientists can trace evolutionary paths and better understand the mechanisms of natural selection and adaptation. Overall, vestigial structures highlight the dynamic nature of evolution and the relationship between different species.
Vestigial structures are remnants of organs or features that were functional in an organism's ancestors but have reduced or lost their original function over time. The presence of these structures suggests that present-day organisms have undergone evolutionary changes from their ancient ancestors. These structures provide evidence for common ancestry and support the theory of evolution.
Fossil records, comparative anatomy, molecular biology, and observed natural selection in various species all provide evidence supporting the theory of evolution. Additionally, geographical distribution of species and the occurrence of vestigial structures in organisms offer further insights into evolutionary processes.
Vestigial structures are remnants of organs or traits that were functional in ancestral species but are reduced or non-functional in present-day organisms. These structures provide evidence of evolution because they suggest that organisms have evolved from ancestors with different adaptations, and over time, structures that are no longer useful have become reduced or lost. This supports the idea that organisms have changed over time to adapt to their environment through the process of evolution.
Embryonic development can show similarities among different species, which suggest a shared ancestry and evolution from a common ancestor. The presence of vestigial structures in embryos, such as gill slits in human embryos, can also provide evidence of evolutionary history. Additionally, comparisons of the timing and sequence of embryonic development in different species can provide insights into their evolutionary relationships.
Homologous structures among animals are similar body parts that suggest a common ancestry. These structures provide evidence for evolution because they indicate that different species share a common evolutionary history and have evolved from a common ancestor.
The study of comparative anatomy and embryology can provide evidence of evolution by showing similarities in structures across different species, suggesting a common ancestry. Fossil records and molecular genetics can also provide evidence by tracing the evolution of species over time and showing genetic relatedness between different organisms.
The theory of evolution is supported by various forms of evidence, such as fossil records showing gradual changes in species over time, similarities in DNA between different species indicating common ancestry, observed speciation events, and the presence of vestigial structures in organisms. These lines of evidence provide a robust foundation for the theory of evolution as a fundamental concept in biological science.
