because their presence allows exons to be shuffled.
Introns were copied and then removed from the RNA sequence because they were placeholders.
Introns are the non-coding parts of the gene. If you didn't remove introns, the wrong protein may be produced because they allow more than one protein to be produced from a single gene.
Mutations in introns are less likely to affect phenotype because introns are not translated into protein, unlike exons which contain coding regions for proteins. Introns are involved in regulation of gene expression through processes such as alternative splicing, but mutations within introns typically have a more subtle impact on gene expression compared to mutations in coding regions (exons).
Prokaryotes do not have introns in their DNA because they lack a nucleus and have a simpler genetic organization compared to eukaryotes. Their genes are typically continuous sequences without interruptions, unlike eukaryotic genes which can have introns that need to be spliced out during gene expression.
Look at the sheer amount of DNA that is contained into a eukaryotic gene (eukaryotes have more DNA to code for and so they can leave some of the DNA out, also look at the way the DNA is formed i.e. Eukaryotic genes are double stranded helixes and prokayrotic genes are a single strand of circular dna.

Yes, cultural evolution can occur much faster than biological evolution because cultural traits can be rapidly spread and adopted among populations through communication, imitation, and technology, whereas biological evolution relies on genetic changes that accumulate over generations through the process of natural selection. This allows cultural adaptations to occur more rapidly in response to changing environments or social needs.

Fossils are evidence of biological evolution because they provide a record of past life forms, showing the progression of species over time. By studying fossils, scientists can trace the development and diversity of organisms, providing insight into how species have evolved and adapted to changing environments.
Eukaryotes have introns in their genetic material because they allow for alternative splicing, which enables a single gene to code for multiple proteins, increasing genetic diversity and complexity.
Introns are removed before cloning a gene because they do not code for proteins and their presence would result in inconsistencies in the protein sequence. Removing introns ensures that the cloned gene only contains the coding regions (exons) necessary for protein production. This process is known as splicing.
Darwin study the Islands of the Galapagos off the coast of Ecuador. These Islands had a large amount of biodiversity which was very astonishing because of there size and remoteness. Each island had its own species of the same animal which is why it was a great place to study the effects of evolution.
because it determines whether a species will evolve to keep up with its predator or prey
No. The introns must be cut out of RNA before transcription. This is because a ribosome cannot read introns, and can only read axons. They are cut out and the axons are attached together to go through ribosome.
