What is common descent with modification?
In short: Evolution. It means that a common ancestor is shared, but through small modifications over long periods of time, there is a large diversity.
How does comparative anatomy not support evolution?
The comparisons between the anatomies of various organisms show common ancestry which supports evolution.
How are vertebrate embryos evidence of evolution?
All vertebrate embryos look roughly the same, showing that they come from a common ancestor.
How did Charles Darwin discovered evolution?
Charles Darwin expanded a common theory of evolution by noting the course of natural selection. He was able to study the categorization of plants and animals species and the beginning of genetics.
What was Charles Darwin's contributions to society?
Charles Darwin theorized that all species come from one common ancestor through evolution.
What is common descent with modification?

What is the current theory of evolution?
That is a very hard question to answer as the "Theory of Evolution" is really an umbrella term for several theories based on the fact that allele frequencies of populations change over time, and the assumption that they have done so for the entirety of life on earth, as well as continuing on into the future. Evolution does NOT claim that there is no God. It makes NO STATEMENT whatsoever about spiritual matters. In fact, statistically speaking, the majority of the people who accept evolution are christians. It also does NOT include big-bang cosmology, does not require a multi-billion year-old earth, and does NOT address the origin of life at all, only its' variety. Current evolutionary theory can be traced to the moment when Darwin proposed his theory on the mechanics of evolution which overturned the previously held view proposed by LaMarck. LaMarcks theory of evolution proposed that an animal gains a trait in its' lifetime and then passes it on. Darwins theory replaced LaMarcks theory by proposing that changes were inherited, but not acquired during the lifetime of the individual. He attributed these changes to random mutations present from birth. Darwin did not stop with a mechanism for these changes, he also divised the "theory of Natural Selection" as a mechanism to favor beneficial mutations. Later, he proposed his "theory of Common Descent" as an explanation of the current variety we see in life. This theory proposes that at some point in the distant past, all living things share a common ancestor. Darwins three ideas have been confirmed through genetics, phylogenics, taxonomy, and paleontology, as well as being supported by every branch of science which can address biology. Through more discoveries, other scientists have developed even more specific theories based on evolution such as, "punctuated equilibrium", "evo-devo", and even the "Out of Africa" theory of human origins. The more we understand about the history of life, the more theories will be developed, but they are all part of evolutionary theory.
Is it true that similarities between seemingly unrelated organisms can be explained by Darwins theory that organisms come from common ancestors?
True
What is the relationship between the fossil record and the scientific theory of evolution?
The fossil record independently confirms the general hypothesis of common descent, and allows palaeontologists and evolutionary biologists to confirm specific proposed phylogenies as well as specific hypotheses about the evolutionary past of various lineages.
What common factor was involved in all of the hypotheses to explain the collapse of Easter Island society?
Deforestation
What are 2 hypotheses of evolution?
I believe you are referring to microevolution and macroevolution. These theories both support evolution, but each in their own way. Microevolution is the most common belief today. This states that evolution is happening so rapidly that we don't even notice it. The mutations needed for evolution happen so quickly and on such a small scale that we never realize it's happening until afterwards. Macroevolution is exactly the opposite. This states that the mutations take so long that we never notice it. Both theories, in fact, were proposed because people were asking why, if evolution actually did take place, we could never see it happening.
Is similarities an early development not evidence for evolution?
It does hint at common ancestry so it is "evidence" of evolution.
Is evolution a noun?
Yes, the word evolution is a noun, a common, abstract noun; a word for a process, a thing.
What does History and Science have in common?
one part is evolution
The most common basis for grouping organisms?
Evolution
What does natural selection evolution and adapation have in common?
say hhi It does not It does not
Do humanists believe in evolution?
Humanism is a broad philosophy which focuses around human welfare. Evolution and humanism have little in common.
