Concept explainers
To determine: Whether the biological species definition is likely to work for the classification of insects in amber.
Introduction: The word “species” is derived from Latin, which means kind. The efforts to classify species on different bases started from very ancient time. In the ancient times, various plants and animals were defined by their external features like morphology and structure.
To determine: Whether the biological species definition is likely to classify asexually reproducing plants.

- The biological species concept defines a species by its morphology. In other words all members of the same species look alike? True or false?arrow_forwardThe 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_forwardWhile there are many criteria to describe the difference between two species, the biological definition of a species is based on being part of?arrow_forward
- Which of the following concepts applies to both sexual and asexual species? Select all that apply. Question 29 options: Linnean species concept Phylogenetic species concept Fossil species concept Biological species concept Morphological species conceparrow_forwardn which situation would it make sense to use the phylogenetic species concept? When you are not able to collect data about how individuals in your study use their habitat, but you are able to collect reproductive data 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 you only have genetic data about each organism in your study When working with fossils from extinct organismsarrow_forwardYou 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? * Pre-zygotic barriers have forced them to be separate species. They are in Hardy-Weinberg equilibrium. Microevolution is occurring in both variations. They are two separate species. Two species of toads are reproductively isolated due to the fact that one species mates in early summer and one in late summer. Both species of toads evolved from a common ancestor. What type of speciation occurred?* OAllopatricarrow_forward
- What notion is common to morphological, phylogenetic and biological species concepts?arrow_forwardWhat type of species concept would you use to classify extinct species that only exist in fossils? Biological species concept Phylogenetic species concept Ecological species concept Morphological species concept Interactive species conceptarrow_forwardThe monarch butterfly (Danas plexippus) and the viceroy butterfly (Limenitis archippus) look almost identical. Which species concept might have led taxonomists to incorrectly classify them as the same species? VICEROY MONARCH binomial species concept phylogenetic species concept Linnaean species concept morphological species concept biological species conceptarrow_forward
- Two biologists are arguing at a conference. One says that the Biological Species Concept (BSC) is superior. Her colleague argues that a different species concept is needed. Which of the following claims of the biologist are true and which are false? 1. The BSC potentially would work for all multicellular organisms. 2. A Morphological Species Concept would work better for cryptic species than the BSC. 3. If two populations of snails are separated by a huge distance, they cannot mate. This means the BSC cannot apply to them.arrow_forwardWhat 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_forwardObserve the three species of fruit fly and their evolutionary relationships in the tree below: Fly species 1 MRCA of fly species 1 & 2 Fly species 2 Note that the three fly species have the following characteristics: Fly species 1: white eyes, lots of leg bristles, striped wings Fly species 2: red eyes, lots of leg bristles, striped wings Distant relative: white eyes, lots of leg bristles, plain wings Distant relative Q3. What are the most likely characteristics of the most recent common ancestor (MRCA) of fly species 1 and fly species 2, labeled in the diagram above? Lots of leg bristles; can't tell on the other two traits Lots of leg bristles, striped wings; can't tell on eye color Lots of leg bristles, striped wings, red eyes Lots of leg bristles, striped wings, white eyesarrow_forward
