Concept explainers
To determine: Whether the problem of divergent opinions on deducing history and correct interpretation of diversity patterns among taxa is resolved.
Introduction: The exact history of the events and correct order of diversity patterns which led to the current biological diversity and habitat are very difficult to determine. The ecological niche conditions are very different from the current time. Hence, there were many hypotheses for history and patterns of diversification. The diversification rate of different species increases when members of that species come in contact with a new geography.

Check out a sample textbook solution- Phylogeny refers to the evolutionary descent of taxa. It refers to the relationship between ancestors and descendants and relationships among descendant taxa. It shows the lineage of taxa which can be summarized in a branching diagram called a phylogenetic tree.1. Express some basic evolutionary relationships among groups of microorganisms, plants, and animals; 2. Illustrate the relationship of organisms with their environment; and 3. Analyze environmental factors contributing to biodiversity richness and lossarrow_forwardStudy the diagrams below. The diagrams represent four possible phylogenetic trees showing the relationship between the four species: M, L, S, and R. B A M LS R M LR +d \t R SML RM S tota -444 What is the plausible explanation for the appearance of autapomorphic character c in species L and S of tree A although they do not share a most recent common ancestor?arrow_forwardPlease associate the explanation with the correct de-extinction methods, some of which are still only possible in theory. Genes from extinct species are cut and pasted into the genome of a relative species using the molecular tool CRISPR. Relatives of the extinct species are hybridized or selected of specific traits with the goal of creating morphologically similar species that can perform the same ecological function as the extinct relative. The nucleus of an intact cell from an extinct species is inserted into the egg of a living relative. 1. Back-breeding 2. Cloning 3. Genomic reconstructionarrow_forward
- n which situation would it make sense to use the morphological species concept? When you are able to collect data about how individuals in your study use their habitat, but you are unable to determine if they interbreed When working with fossils from extinct organisms When you only have genetic data about each organism in your study When you are not able to collect data about how individuals in your study use their habitat, but you are able to collect reproductive dataarrow_forwardPhylogeny refers to the evolutionary descent of taxa. It refers to the relationship between ancestors and descendants and relationships among descendant taxa. It shows the lineage of taxa which can be summarized in a branching diagram called a phylogenetic tree.a. express some basic evolutionary relationships among groups of microorganisms, plants, and animals; b. illustrate the relationship of organisms with their environment; and c. analyze environmental factors contributing to biodiversity richness and lossarrow_forward1) How have scientists created the "tree of life"? Do you think that variations exist between these created trees? 2) What are the pros and cons to creating a "tree of life"? 3) When constructing this tree of life we can see many dead ends or organisms that we are unsure of their exact placement. Why is this? 4) Choose one species (either alive today or extinct) and describe its taxonomic classification. What traits or characteristics were used to classify this species into its current taxonomic classification? What other organisms are considered to be its closest relatives?arrow_forward
- The biological species concept depends on the existence of barriers to reproduction. What are they? Does this species concept apply in all situations? Think of an example from nature where the biological species concept would NOT be that applicable. Which species concept would be better in this example? How does speciation occur? What environmental factors might contribute to speciation? Can an individual speciate? Use terminology for the two kinds of speciation we have learned about. What is “gene flow”? What does it mean if there is NO gene flow? Two groups of individuals are separated by either side of a canyon. One researcher found that they do not cross the canyon at any point. The group on the north side have fluffy tails and thicker coats, and they do not eat moss. The south side individuals eat moss almost exclusively, have a thin coat and tail, but otherwise are generally identical. When in the lab they mated successfully, and the offspring of that mating also mated…arrow_forwardBelow are phylogenetic trees depicting the relationships among four species, A, B, C, and D. Which of the following statements is correct? ABCD ADCB DCBA D CAB (1) (2) (3) (4) Tree (1) and Tree (2) are the same tree. Tree (2) and Tree (4) are the same tree. Tree (2) and Tree (3) are the same tree. All four trees are in fact the same tree. All four trees are in fact different trees.arrow_forwardPlease compare these phylogenetic trees and choose the most accurate statement about whether they are the same tree or not. A a Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. b с DCBE d E A They are not the same because the overall shape looks different. They are not the same because they show different relationships among species. Nodes have been rotated but the species relationships are the same. They are the same because they have the same species at their tips. D C Barrow_forward
- Examine the following phylogenetic tree illustrated in Figure shown in the first picture. In general, what does a phylogenetic tree illustrate? How do you compare the relationships of organisms BB, CC, and DD? Given the following organisms in the Table in the second picture, number them in terms of which is relatively closest and distant. Number 1 refers to closest.arrow_forwardMany pairs of sister taxa differ markedly in their numbers of extant species. In this chapter we saw huge disparities—for example, between lepidopterans and their sister group, caddisflies. What factors (both general and specific) might account for differences among taxa in their numbers of extant species? Suggest methods for determining which factor might actually account for an observed difference.arrow_forwardStep 1: select two different species (one eukaryotic and another prokaryotic and dothe taxonomy. Step 2: Classify each one based on modern taxonomy, and write their scientific namein three different ways based on Linnaeus. Step 3:Describe their dichotomous key and show how far they are in their taxonomyfrom each other and describe how they interact together in the ecosystem basedon what you studied.
