Concept explainers
(a)
To determine:
The species concept that could be applied to both sexual and asexual species
Introduction:
Species are the part of a population that shares similar traits with each other. They have the potential to interbreed and produce viable offsprings in turn. The four different types of species concept are: the typological species concept, the biological species concept, the evolutionary species concept, and the recognition species.
(b)
To determine:
The most useful concept for identifying species in the field.

- 8) What data would suggest that a species evolutionary history includes sexual selection as a mechanism that helped shape the species? A) If males and females are significantly different from each other (sexual dimporphism) B) If some males reproduce with multiple females while other males do not reproduce C) If males engage in "risky" behavior D) If males and females form different social groups (i.e. herds are formed from either males or females but not both)arrow_forwardWhich of the following sexual traits is LEAST likely to have evolved due to male-male competition for mates, also known as intraspecific sexual selection?a) Enlarged femurs that an insect uses to kick other malesb) Brushes on the tip of a dragonfly penis used to remove sperm of other malesc) Mate-guarding behavior of a warbler during the female’s fertile periodd) Elongated tails of the male swordtail fish used during courtshiparrow_forwardPlease use and cite any source(s) you can find to answer the following questions:1. List and describe the different ways in which species are defined.2. Explain how each of the following makes it difficult to clearly define a species: variation within aspecies, geographically isolated populations, asexual species, fossil organisms.3. List and describe the pre-zygotic barriers as well as the post-zygotic barriers.4. Explain why allopatric speciation would be less likely on an island close to a mainland than on a moreisolated island.arrow_forward
- We learned from hermaphroditic snails in New Zealand and C. elegans that populations that are undergo both sexual and asexual reproduction in the same population can alter the frequency of outcrossing resulting in changes in genetic diversity. Identify the statement that accurately reflects a real result. a. Sexual reproduction prevents the ability of snails and worms to coevolve with their parasites. b. Sexual reproduction frequency increases in the presence of a stressor, like pathogens and parasites. c. Asexual reproduction is favored when there are pathogens and parasites in the environment. d. Asexual reproduction enables the Red Queen hypothesis to play out and enable the pathogen to win.arrow_forwardgive one species that is classified or exhibit the following: sex-role reversal show a photograph of it with its sexual traits (body stuctures, behavior, etc) and how these traits help their reproduction. explainarrow_forwardHow can be Palawan bearcat commonly known as Palawan binturong or asian bearcats speciated?arrow_forward
- You are studying two variations of banana slugs. They have similar coloration and live in the same habitat. Although they are physically able to mate, there are no offspring that survive embryologic development. What can you conclude about the banana slugs? * O Pre-zygotic barriers have forced them to be separate species. They are in Hardy-Weinberg equilibrium. O Microevolution is occurring in both variations. O They are two separate species.arrow_forwardn 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_forwardIs sexual reproduction required to generate the variability in structures and behaviors that is necessary for natural selection?arrow_forward
- Based on the biological species concept, which of the following would lead biologists to conclude that different populations of lizards were actually a single species rather than two different species? A.) lizards from the two different populations mate rarely, and produce hyrbid offspring that are sterile B.) Lizards from the two differnt populations mate during different seasons C.) Lizards from the two different populations mate regularly and produce sterile offspring D.) Lizards from the two different populations matre regularly and produce viable offspring capable of reprodarrow_forwardInterspecific hybrids, if they survive, are (a) always sterile (b) always fertile (c) usually sterile (d) usually fertile (e) never sterilearrow_forwardIn at least some animal groups (for example, reptiles) asexual species tend to be over-represented on islands compared to mainlands, because it is easier for them to colonize. Offer two reasonable hypotheses why asexual species might be more likely to colonize islands than sexual species. Briefly describe your reasoning for each.arrow_forward
