Which Best Explains the Genetic Similarities Between Species

Each population of the same species also contain different genetic compositions. B The DNA becomes more complex as we move from lamprey to human.

Genetic Similarities Wilson Sarich Sibley And Ahlquist Understanding Evolution

Some molecular data place the giant panda in the bear family Ursidae but place the lesser panda in the raccoon family Procyonidae.

. Similarities between even widely disparate types of organism exist at every level from. Vestigial traits are those that no longer function in an organism. C possession of analogous structures.

Some studies reveal only a 12 difference in the DNA. After Darwin proposed this theory the process of classifying species was modified to show the relationships among different species. Genetic analysis reveals that humans are most closely related to chimpanzees and bonobos.

It can also be seen as a powerful argument for a master designer. The basic unit of life on earth is the gene. Embryology The evolutionary relationship between pigs and humans is supported by observations showing similar stages of prenatal before birth development in these organisms.

This variation is best appreciated by focusing on three particularly thorough analyses all in Drosophila. A 99 genetic similarity between chimps and humans is not a knock down argument for evolution. The theory of evolution accounts for the diversity of life but it also explains the fundamental similarities between different species.

Line of evidence 3 the fossil record is a line of evidence that provides information on transitional species. The less genetic difference there is between chimps and humans or the less reworking it takes to. Line of evidence 2 genetic material is the comparison of genetic and biochemical similarities to indicate evolutionary relationships.

The individuals of each species comprise their own specific genetic composition. Charles Darwin proposed the theory of evolution which stated that all species developed by inheriting useful variations of their ancestors and gradually new species were formed. The morphological species concept groups species according to morphological similarities and ignores other differences such as DNA or inability to reproduce between individuals.

More closely related species will have more similarities in dna D. There is no link between the relationships of species and their dna. More closely related species will have identical dna B.

The traditional naive model in which commonalities between species are ignored implicitly takes all similarities between distinct species to be zero. The evidence for evolution shows how the similarities between living creatures can be understood in terms of evolution. A The DNA sequences vary for each type of vertebrate.

Investigators are trying to determine the degree of evolutionary relatedness among four different prokaryotic organisms. Competition for limited food resources led to selection for different traits. The morphological species concept stems from the morphology which is the study of the physical aspects of an organism and their arrangement.

Humans chimpanzees and orangutans have a GULO pseudogene and are unable to produce ascorbic acid. Over time an abundance of seeds for food led to increased similarities between the species. The base sequences are found in the table above.

Click hereto get an answer to your question After comparing DNA sequences of several mammals the lesser panda and the giant panda were reclassified as belonging to different taxonomic families with the giant panda staying classified in the family of Ursidae bears and the lesser panda now being classified in the family of Procyonidae raccoonsWhich of the. When two species share a large number of homologous traits it is evidence that they share a recent common ancestor. More closely related species will have fewer dna similarities C.

D There are no genetic similarities among the vertebrates in the cladogram. Line of evidence 1 anatomical evidence is the comparison of physical structures between species. However primates that live in other places 09.

Response to artificial selection within species often involves many genes 7 the most striking feature of the between-species data shown in Table1 is its lack of consistency. There is a mix of results ranging from one to many genes. The irony is that this shows that our starting premise was kind to the evolutionist.

Human activity on Madagascar including poaching drove the other primates into extinction on the island. Of similarity will lead to a measure of genetic diversity a functional notion of similarity will lead to a measure of functional diversity and so on. The correct answer was given.

Click hereto get an answer to your question After comparing DNA sequences of several mammals the lesser panda and the giant panda were reclassified as belonging to different taxonomic families with the giant panda staying classified in the family of Ursidae bears and the lesser panda now being classified in the family of Procyonidae raccoonsWhich of the. Gene is responsible for all of the characteristics both the similarities and the differences between organisms. Which of the following best explains the genetic variation among primate species.

This leads to a naive measure of diversity. They study the DNA base sequence of a gene called RS1 that is similar in all four species. Which of the species are MOST closely related.

Consequently the morphological similarities of these two species are probably due to A inheritance of acquired characteristics. Over time an abundance of seeds for food led to increased differences between the species. Which concept do biologists frequently use to explain the similarities between different species in early embryonic development.

The presence of vestigial traits can also help determine relationships between species that possess homologous traits that still function. The correct answer would be that more closely related species will have more similarities in DNA. C Both DNA sequences and amino acid sequences vary among the vertebrates.

Which statement BEST explains the genetics represented by the cladogram. The DNA stores the genetic information of organisms and contains a set. Which best explains the genetic similarities between species.
