The lines of evidence are multitudinous and in order to find some of the answers you will need to study long and hard at length and in depth, as so many have done since before Darwin. Take a university degree course and be enlightened. http://en.wikipedia.org/wiki/Evidence_of_common_descent
There is ample evidence of a common ancestor for all life on Earth, known as the Last Universal Common Ancestor (LUCA). This is supported by various lines of evidence, including genetic similarities, shared biochemical pathways, and the universal presence of certain biomolecules across diverse species.
Yes, evidence supporting the common ancestry between two different species includes similarities in genetic sequences, anatomical structures, and developmental patterns. Additionally, the fossil record often reveals transitional forms that link different species together. Overall, these lines of evidence strongly support the theory of evolution and common ancestry among living organisms.
the fossil record, comparative anatomy, molecular biology, and biogeography. These lines of evidence all point towards a shared ancestry among different species, providing support for Darwin's theory of evolution by natural selection.
A common ancestor that gives rise to two or more distinct lines of descent is known as a "common ancestor" or "ancestor of divergence." This individual represents the point in the family tree where two or more branches split off and evolve independently over time.
The lines of evidence that support the theory of evolution include fossil records, comparative anatomy, molecular biology, and biogeography. Fossil records show a progression of life forms over time, while comparative anatomy reveals similarities in structures among different species. Molecular biology demonstrates common genetic sequences among organisms, and biogeography examines the distribution of species around the world, all of which provide evidence for the common ancestry and gradual change of species over time outlined in the theory of evolution.
Evidence for evolution includes the fossil record, comparative anatomy, molecular biology, and observed instances of natural selection. These different lines of evidence all support the concept of biological evolution occurring over time.
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.
The evidence for evolution is extensive and multi-layered, too much for me to cover comprehensively. The Wikipedia article 'Evidence of common descent' has many subcategories. these are: Evidence from genetics Evidence from palaeontology Evidence from comparative anatomy Evidence from geographical distribution Evidence from comparative physiology and biochemistry Evidence from antibiotic and pesticide resistance Evidence from complex iteration Evidence from observed speciation and adaptation Evidence from intraspecies modifications I would recommend the Wikipeidia article and I am sure there are a large number of YouTube videos dedicated to the subject.
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
Evolution is the change in allele frequency over time in a population of organisms. Sequence the genomes of enough organisms in that population at two varying points and you will see the fact of evolution.
Evolution is a fact. The theory of evolution by natural selection is what you are trying to talk about. When someone says " evolution is just a theory " they are using the vulgar, common sense of the word theory. They mean guess, hunch and the like. The theory of evolution by natural selection is in the scientific sense of the word theory, which means a body of explanatory work supported by myriad lines of converging evidence that has been tested rigouusly and replicated often. Any good dictionary uses this scientific meaning of theory as the primary meaning of the word.
Numerous scientific disciplines, such as genetics, paleontology, and comparative anatomy, provide evidence supporting Darwin's theory of evolution. Fossil records show transitional forms between species, genetic studies demonstrate shared ancestry through common DNA sequences, and observations of natural selection in action support the idea of species evolving over time. These various lines of evidence collectively contribute to the scientific consensus on the validity of Darwin's theory of evolution.
