Dogs (Canis lupus familiaris) and gray wolves (Canis lupus) can interbreed to produce viable, fertile offspring. These species s

hared a common ancestor recently (in geologic time) and have a high degree of genetic similarity, although their anatomies vary widely. Judging from this evidence, which two species concepts are most likely to place dogs and wolves together into a single species?

Answer:

1. Biological Species Concept

2. Phylogenetic Species Concept

Explanation:

Ernst Mayr defined the species on the basis of the biological species concept. Accordingly, the organisms that are capable of interbreeding to produce fertile progeny belong to the same species.  

Since dogs and gray wolves are able to produce fertile progeny, they belong to the same species as per the biological species concept.  

According to the phylogenetic species concept, two organisms that share a recent common ancestor and exhibit certain derived traits, belong to the same species.

According to the given information, dogs and gray wolves are descended from a common ancestor and hence, belong to the same species according to the phylogenetic species concept.

Answer:

Microevolution refers to evolution at or below the species level.

Explanation:

  • If the change occurs in the short period span of time within the specific species then this type of change is refereed to as the micro evolution.
  • Micro evolution is occurred in between small group of animals or species.
  • If the evolution is expanded to community or large population it is not considered as a microevolution.
  • Microevolution may be caused due to mutation, selection, gene flow and genetic drift.

After watching the video, how would you define the term ecological relationship? Are they always beneficial to organisms involve
dangina [55]

Answer:

There is no video but ecological relationship will be defined on a general note and it is not always beneficial to organisms.

Explanation:

In an ecosystem, organisms of the same or different species tend to interact with one another. This interaction is referred to as ECOLOGICAL RELATIONSHIP between the involved organisms. An ecological relationship can be of different types depending on the effect.

SYMBIOSIS is an ecological relationship between two organisms that interact together. SYMBIOSIS can either be mutualistic (both organisms benefit), parasitic (one organism loses and one gains), or commensalistic (one organism benefits and one neither benefits or loses). Another ecological relationship is PREDATION, where one organism called the PREDATOR feeds on part or all of another organism called PREY in order to obtain energy.

As stated above, some of the organisms involved in an ecological relationship benefits while others lose. Hence, it is not always a beneficial relationship to organisms.
