To review:
The given blank space in the given statement, “a species is a group of ______ that evolves _______. The biological species concept identifies species on the basis of their ______. The biological concept cannot be applied to species that reproduce ______.”
Answer to Problem 1FTB
Introduction:
Population comprises all the organisms of the same group or species, living in a specific geographical area. The adaptation process provides the support to the organism to live in that particular environment and thus helps in their reproduction. Organisms involved in a population of a specific area are able to interbreed, thereby supports the process of sexual reproduction.
Explanation of Solution
Species: The largest group of organisms which have the potential to interbreed with the individual of the same group within a geographical area, is known as species. The niche of these individuals is known as their habitat.
Population: The individuals of the same group or species, that are capable to interbreed in a particular geographical area, are known as population. They are thus able to exchange their gametes in order to produce fertile offsprings. The main attribute of a population is recognized by the phenotypic characters of the individuals who are involved in it. These phenotypic characters are governed by alleles. Any change in the allelic frequencies over the years results in the evolution of the individual. Thus the population evolves independently.
Reproductive isolation: The species that are able to breed in their groups in a particular given area are reproductively isolated. This mechanism ensures that an offspring produced from different species of the different geographical area should be infertile in nature. This is a biological phenomenon, which results in speciation.
A sexual reproduction: This is a type of reproduction in which off springs arise from a single parent. This process does not involve the fusion of gametes, thus the information inherited by the offspring is from only one parent. This type of reproduction does not establish genetic diversity into the environment, thus no biological concept can be applied to them.
A species is a group of the population that evolves independently. The biological species concept identifies species on the basis of their reproductive isolation. The biological concept cannot be applied to species that reproduce asexually.

- What criteria are used in the biological species concept to define a species? Choose all that apply.- live in same habitat - have same niche - produce viable offspring - have similar genetics - look similar - produce fertile offspring - have similar ancestryarrow_forwardThe Abert and the Kaibab species of squirrels live on opposite ends of the Grand Canyon. Physically they are very similar to each other, which leads scientist to think that when the Grand Canyon was shallower (millions of years ago) the populations use to have genetic contact (sexual reproduction). In present day, they are completely isolated from each other. When tested the Abert and Kaibab squirrels cannot produce a fertile offspring. This is an example of ___ speciation.
