Answer:

scientist can learn how the rat has evolved based on where they live. it also helps find what the common ancestor was and all the common traits they have, for example rats in Norway may be used to the cold. and the rats in africa need to adapt to the heat and the constant threat of them being eaten.

It certainly is possible that the North American population has to carry different mutations than a population of Norway rats in Africa. Genetic mutation is a random event, and the alleles resulting from mutation may rise in frequency and be fixed within the population if they provide a benefit to the fitness of the individuals with that allele. One random mutation could occur in the North American population and not be found in the African population because the occurrence of this mutation is random. It is also possible that the two populations carry the same mutations. This would be the case if the mutation occurred either if the mutation occurred in a common ancestor, or if the mutation occurred prior to the 2 populations becoming allopatric. By studying the genomes of each population scientists will be able to determine when certain mutations occurred. Mutations found in one population and not the other occurred more recently, while mutations found in both populations occurred further back in evolutionary time, and may have originated in a common ancestor.

Which hypothesis suggests that ancestral vertebrates may have evolved from urochordate larvae?.
Anastaziya [24]

Garstang's Auricularia hypothesis suggests that ancestral vertebrates may have evolved from urochordate larvae.

What is Garstang's Auricularia?

The auricularia hypothesis, proposed by Garstang was an attempt to explain how the chordate body plan originated from a deuterostome common ancestor by emphasizing the significance of changes in larval forms. According to the Garstang Hypothesis, development of sexual maturity in a non-metamorphosing lineage of tunicates might provide the immediate proto-chordate ancestors of more typical chordates.

Which type of mutation affects the largest number of genes
SashulF [63]

Answer:

Chromosomal Mutation

Explanation:

The development and function of an organism is in large part controlled by genes. Mutations can lead to changes in the structure of an encoded protein or to a decrease or complete loss in its expression. Because a change in the DNA sequence affects all copies of the encoded protein, mutations can be particularly damaging to a cell or organism. In contrast, any alterations in the sequences of RNA or protein molecules that occur during their synthesis are less serious because many copies of each RNA and protein are synthesized.

Geneticists often distinguish between the genotype and phenotype of an organism. Strictly speaking, the entire set of genes carried by an individual is its genotype, whereas the function and physical appearance of an individual is referred to as its phenotype. However, the two terms commonly are used in a more restricted sense: genotype usually denotes whether an individual carries mutations in a single gene (or a small number of genes), and phenotype denotes the physical and functional consequences of that genotype.
