Did Charles Darwin have evidence to prove evolution?
No, of course not. Evidence does not prove evolution - it validates the theory.Evidence which Darwin had included limited fossils, and observed apparent speciation in birds.
Why did Charles Darwin started the theiry of evolution?
To explain the species problem, " that mystery of mysteries " which was the natural history problem of the day. From his observations and experiments Darwin proposed his theory of evolution by natural selection, which provided a mechanism for the observed fact of evolution.
What animals eyes don't reflect?
All animals, even humans have some degree of light reflection. This is often apparent in animals that are often observed by humans, such as dogs and cats.
What is used as evidentiary support for evolution by scientists?
Evolution is the change in allele frequency over time in a population of organisms. By sequencing genes one can see this happen. Also just observing the morphological and behavioral changes in populations over time can lead to evidence supporting evolution. Check Lenski and his E. coli experiments. Over 20 years evolution was observed in these microorganisms. Fairly easy Google.
What have Darwin observed during his voyage on the HMS Beagle?
He saw birds of striking different form and structure to those of Europe and went further to establish that it was due to evolution.
Have humans ever observed evolution happening?
Evolution is routinely observed both in nature and in the lab. Even several speciation "events" are on record.
Has evolution been observed?
Yes. Evolution is routinely observed in both labs and in nature.
Why is evolution not an observed fact?
A:Evolution of species is the process by which each species developed from earlier species. Some people believe that, because it requires a great many generations and noticeable changes normally take place over periods far longer than the human lifetime, evolution can not be observed directly and can only be imputed indirectly from fossil finds and DNA evidence. However, bacteria have extremely short lifespans and evolution can indeed be observed in them. The evidence of evolution is clearly seen in numerous fossils and in DNA. Even if not observed in real time, this evidence is regarded as conclusive.
What changes have been observed during the evolution of heart and brain?
None have been directly observed. Our ability to analyse in detail the structures of the human anatomy is fairly new. In the short time since we've been able to map neural structures and neurochemical patterns, no significant evolution can be expected to have occurred.
Why are adaptations evidence of evolution?
Because adaptations are an observed effect of evolution. They could not happen if evolution did not occur.
How does observed evolutionary change support the scientific theory of evolution?
The theory predicts that evolution will happen and in certain ways. The observed evolution makes this prediction correct. It also defines evolution as happening, and as such is perfect evidence in support of it.
Why can't dark matter be directly observed?
If it could be directly observed then it would not be called dark matter!
Is a quark the same as an energy level?
No, Higgs Boson is a theoretical particle yet to be observed directly or indirectly by humans. Quarks on the other hand have been observed directly and indirectly. Also, the Higgs boson is responsible for a field, however quarks are responsible for matter, and are the basic constituents of the nuclei in atoms.
Scientists have observed evolution on a rapid time scale in what organism?
Bacteria
Scientists have observed evolution in a rapid time scale in what organism?
Bacteria
Why is evolution not a pseudoscience?
Evolution, the change in allele frequency over time in a population of organisms, is an observed and observable fact. That's why.
What did the theory of human evolution say?
There is no separate theory of evolution for humans. Human evolution is the theory of evolution applied to humans. Evolutionary theory states that modern lifeforms, including humans, derive from common ancestors through a process of reproductive variation and natural selection.
