Chapter 24: Q24-7TYU (page 522)

Explain the biological basis for assigning all human populations to a single species. Can you think of a scenario by which a second human species could originate in the future?

Short Answer

Expert verified

In accordance with the scenario, a second human species can originate a new individual in the future. However, this complete process will take a lot of time. Also, the individual formed will possess its features without similarity.

Step by step solution

01

Evolution

Evolution is explained as the phenomenon through which the life form originated billions of years ago, modified and diversified into different groups inhabiting today's world. Darwin proposed the theory associated with evolution.

02

Human species

Human beings fall under the category of culture-bearing primates. Its genus is demarcated as Homo, while the species is described as sapiens. It is acknowledged that human beings are physically alike and connected to the great apes.

However, humans possess a highly advanced brain and a subsequent capability for lucid speech.

03

Step 3: Origination of human species in the future

The species can be described as reproducing inhabitants that yield fertile offspring. The human population possesses this quality, therefore, leading to it all being a similar species.

Two diverse groups of humans would have to come from two different clusters that have no aspects in terms of each other. They would require to grow as their individual without similarity as the other one.

They would possess the necessity to acclimatize to their own diverse environment.This could not occur for a while, though, as the species would require colossal time to develop its own and have no resemblances to the other.

Human beings fall under the category of culture-bearing primates. Two diverse groups of humans would have to come from two different clusters and will take a lot of time to develop the individuals that possess their own characteristics features.

Calculate the value of the reproductive isolation index if (a) allof the matings within a population were successful, but noneof the matings between populations was successful; (b) salamanders are equally successful in mating with members of their own population and members of another population.

In this chapter, you read that bread wheat (Triticum aestivum) is an allohexaploid, containing two sets of chromosomes from each of three different parent species. Genetic analysis suggests that the three species pictured following this question each contributed chromosome sets to T. aestivum. (The capital letters here represent sets of chromosomes rather than individual genes, and the diploid chromosome number for each species is shown in parentheses.) Evidence also indicates that the first polyploidy event was a spontaneous hybridization of the early cultivated wheat species T. monococcum and a wild Triticum grass species. Based on this information, draw a diagram of one possible chain of events that could have produced the allohexaploid T. aestivum.

Suppose two bird species live in a forest and are not known to interbreed. One species feeds and mates in the treetops and the other on the ground. But in captivity, the birds can interbreed and produce viable, fertile offspring. What type of reproductive barrier most likely keeps these species separate in nature? Explain.

Bird guides once listed the myrtle warbler and Audubon's warbler as distinct species. Recently, these birds have been classified as eastern and western forms of a single species, the yellow-rumped warbler. Which of the following pieces of evidence, if true, would be cause for this reclassification?

(A) The two forms interbreed often in nature, and their offspring survive and reproduce well.

(B) The two forms live in similar habitats and have similar food requirements.

(C) The two forms have many genes in common.

(D) The two forms are very similar in appearance.

Which of the following factors would not contribute to allopatric speciation?

(A) The separated population is small, and genetic drift occurs.

(B) The isolated population is exposed to different selection pressures than the ancestral population.

(C) Different mutations begin to distinguish the gene pools of the separated populations.

(D) Gene flow between the two populations is extensive.
