While orangutans and gorillas are in the great ape family, humans are most closely related to two other species in the family: bonobos and chimpanzees.

According to given tree, rodents and primates share most common recent ancestor as these branches are evolved from a common node and so, they are most closely related organisms.

The similarity in the DNA of two species is the best evidence to tell us how closely related the two species are. Another significant source of evidence is the similarities in the amino acid sequence of the proteins of the two species.

The existence of extremely similar species may cause local and global species diversity to be underestimated. The recognition of similar-but-distinct species is important for disease and pest control and in conservation biology although the drawing of dividing lines between species can be inherently difficult.

Ursus maritimus (polar bear) and ursus americanus (black bear) are closely related.

Why is the standard taxonomic system important to the scientific community?

Why is taxonomy so important? Well, it helps us categorize organisms so we can more easily communicate biological information. Taxonomy uses hierarchical classification as a way to help scientists understand and organize the diversity of life on our planet.

What are the limitations of the Linnaean classification system?

The major limitation of the Linnaean classification system is that it is based on physical traits.

What are two problems with the five Kingdom system of classification?

Disadvantages of Five Kingdom Classification Unicellular algae are kept in kingdom Protista, whereas algae like multicelluar organisms are ketp in kingdom Plantae. But similar organisms must be put together. There is diversity in kingdom Protista. Dissimilar organisms must not be kept in same group.

What are the advantages and disadvantages of classification?

Also, what are advantages of classification? The advantages of classifying organisms are as follows: (i) Classification facilitates the identification of organisms. (ii) helps to establish the relationship among various groups of organisms. (iii) helps to study the phylogeny and evolutionary history of organisms.

What are the two advantages of classification?

What are the advantages of classifications of organisms?

  • It makes us aware of and gives us information regarding the diversity of plants and animals.
  • It makes the study of different kinds of organisms much easier.
  • It tells us about the inter-relationship among the various organisms.
  • It helps to understand the evolution of organisms.

What are the advantages and disadvantages of two kingdom classification?

1) Plants and animals were divided into two kingdoms not abruptly but based upon specific characters. 2) It initiated systematic methods to classify the living organisms. More and more characters were, later, taken into consideration for development of better methods.

What are the four main merits of classification?

what are the merits of classification of data

  • Simplification.
  • Briefness.
  • Utility.
  • Comparability.
  • Attractive and Effective.
  • Scientific Arrangement.

What are the advantages of natural classification?

This is opposed to an artificial classification in which the members of a group only resemble each other in the defining characters; they show no similarities for non-defining characters The advantage of natural classification is that it is possible to predict the distribution of other characters from the …

What is a natural classification?

Natural classification involves grouping organisms based on similarities first and then identifying shared characteristics. According to a natural classification system, all members of a particular group would have shared a common ancestor.

What is the basis of natural classification?

The natural system of classification of organisms is according to a relationship based on descent from a common ancestor. In this classification, the organism is classified on the basis of their vegetative characters which are permanent and do not change with the environment.

What are the two types of classification?

Classification by Attributes or Qualitative classification Classification according to attributes is of two kinds: simple classification and manifold classification.

Who proposed natural system of classification?

Bentham and Hooker

Who gave the natural system of classification?

G. Bentham

Who is called as father of taxonomy?

Carolus Linnaeus

Who proposed five kingdom classification?


What was the four Kingdom system of classification?

By 1959, Robert Whittaker proposed that fungi, which were formerly classified as plants, be given their own kingdom. Therefore, he divided life into four kingdoms such as: Protista, (or unicellular organisms); Plantae, (or multicellular plants);

What advantages does the five kingdom classification have over the two kingdom classification?

Five kingdom classification is better and more natural than two kingdom classification. It places the unicellular and multicellular organisms separately. It places the autotrophs and heterotrophs separately. It places the fungi in a separate group (kingdom Fungi) as it has a different mode of nutrition.

On what basis is the Six Kingdom classification?

Woese found that the six kingdoms naturally cluster into three main categories, based on the sequence of 16s ribosomal RNA genes. He called these categories as domains of life. These domains are Bacteria, Archaea, and Eukarya. He also believed that these domains have originated from common ancestors called Progenote.
