How do genetic disorders such as cystic fibrosis support the theory of evolution?
Wiki User
∙ 13y ago
Cystic fibrosis and other autosomal recessive diseases are not commonly put forward as strong evidential support for the theory of evolution, but being recessive, there is little negative selection pressure to remove the implicated mutations from the gene pool. Another factor to consider is that there are some indications of heterozygous advantage in the form of resistance to cholera, typhoid, diarrhea, and tuberculosis.

∙ 13y agoGenetic disorders such as CF support the theory of evolution because the CF allele is carried by roughly 1 person in 25 of European ancestry.

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.
How does genetic variation support Natural Selection?
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.
What evidence did Stephen Jay Gould use to support his theory?
The discontinuities in the fossil record that seemed to show that some species or taxons were in a state of non-evolution and then seemed to go through a burst of rapid evolutionary change. This is really only seen in the fossil record and does not have a lot of support in disciplines such as molecular genetic, which genetic divergence back through time in today's genomes.
How Does Homologous Structures Disapprove Evolution?
They don't, Homologous structures, such as the bones in your forearms and the bones in your cat's and dog's forelegs are that similar because you and your pets are mammals and closely related on the evolutionary tree. Before modern genetic showed this to be convincing the study of morphology was showing us pretty much the same thing; homologous structures support evolution.
How does Josiah Strong show that he supports the theory of evolution?
There is strong support for the theory of evolution due to fossils that have been found by archeologists. The fossil records show evidence of evolution over billions of years.
What are the types of evidence for evolution?
Evolution is the change in allele frequency over time in a population of organisms. This is an observed and observable fact.The molecular, genetic and fossil record all bear out evolutionary change and support one another by being cross correlated. Go here.talkorigins.org
Is evolutionary true?
Yes, the theory of evolution is widely accepted as a scientific fact. It explains the diversity of living organisms on Earth through the process of natural selection, genetic variation, and adaptation over time. Multiple lines of evidence from various scientific fields support the theory of evolution.
Do any qualified scientists support evolution?
The vast majority of scientists support evolution. There is no longer any debate in the scientific community about whether evolution occurs, only the mechanisms in which evolution acts upon is debated.
Do Americans support eating disorders?
No, not at all.
Does genetics support evolution?
Genetics is the study of genes, heredity and variation of living organisms in biology. Molecular genetics supports evolution as its processes work in combination with the environment and experiences of an organism to influence their development and behavior.
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.

What theory does the fossil record support?
It is generally thought to support the Theory of Evolution.
Does the existence of intermediate forms support or not support the theory of evolution?
Intermediate forms are predicted by evolutionary science in several ways. Their presence supports the theory of evolution.
Support for people with eating disorders?
People with eating disorders can find support in many different forms and places. Therapists, medical professionals, and trained professionals can offer support, especially in the form of recovery help. Kind support can also be found in friends and family. Groups and organizations are often set up for people recovering or for those who have recovered from eating disorders, too.
Do you believe that this evidence gives support to the theory of evolution?
I do not so much " believe it " as I an convinced by the myriad lines of converging evidences that support the theory of evolution by natural selection. talkorigins.org
