Which statement provides evidence that evolution is still occurring at the present time?

There is no reason to think the same forces that shaped species in ages past are not still at operation. These forces are genetic drift and natural selection. And we find them still in operation, gradually modifying the phenotype of species. US sparrows, descended from European sparrows, have accumulated slight differences over just a few centuries. Drug resistance in various pathogenic bacteria is another example.
Replication is inexact--every individual is slightly different from its parents, and these changes accumulate.

∙ 13y agoThe simple definition of evolution. Evolution is the change in allele frequency over time in a population of organisms. This violates the Hardy-Weinberg strictures and thus evolution is occurring.

How cytochrome c provides evidence of evolution?

What provides evidence for evolution?
The fossil record, although not complete, provides a lot of evidence. There is also supporting evidence from geological studies, and the extensive human and nonhuman genome studies that are currently being done.
What provides evidence that evolution has led to the development of modern species?
This question can not be answered without more information.
What study provides evidence of evolution?
Paleontology, genetics, molecular Biology, taxonomy, evolutionary development and comparative anatomy, just to name a few.
Do Introns represent a genome scrap yard that provides DNA segments for genome evolution and a variety of small RNA molecules?
yes

What evidence does evolution provide?
The change in allele frequency over time in populations of organisms. An observed and observable fact, especially since gene sequencing has come into it's own. More to the point, evolution provides us with the evidence for evolutionary theory.

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.
A Foucault pendulum provides evidence of Earth's?
it provides evidence of the EARTH's rotation.
Do you agree that mission statement provides a substantive guidance and a vision statement provides inspirational guidance?
Yes, I agree.
What evidence of evolution can be found in the geographic distribution of living animals?
All organisms are adapted to their environment to a greater or lesser extent. If the abiotic and biotic factors within a habitat are capable of supporting a particular species in one geographic area, then one might assume that the same species would be found in a similar habitat in a similar geographic area, e.g. in Africa and South America. This is not the case. Plant and animal species are discontinuously distributed throughout the world
Why the statement of cash flows provides useful information that goes beyond income statement and balance sheet data?
statement of cash flows provides useful information that goes beyond income statement and balance sheet data because provides information to security analysts and stockholders
Similarity of structure of the forelimb of a bird and a mammal is an example of what evidence?
Homologous structures - the forelimb structures are anatomically similar and were derived from a common ancestor; however, they have evolved completely different uses. This provides evidence for divergent evolution or adaptive radiation.
Which statement provides evidence that the seafloor is spreading out from both sides of the Mid-Atlantic Ridge?
parrell strips of igneous rocks on each side of the ridge show matching reversal of magnetic polity
