What factor is necessary for the formation of new species?
For speciation to occur, two new populations must be formed from one original population; they must evolve in such a way that it becomes impossible for individuals from the two new populations to interbreed.
Which of the following will form new species?
The correct answer is b. Variation. According to Darwin’s theory of evolution, variations, when accumulated over a long period of time lead to the origin of a new species. Regards.
Which concept is not included in the modern theory of evolution?
Biology Final Review
| Question | Answer |
|---|---|
| Which concept is NOT included in the modern theory of evolution | transmission of acquired characteristics |
| Which phrase best defines evolution by natural selection | a process of change in species over time |
| Examples of fossils include preserved | -eggs -footprints -body parts |
What are 5 ways species can become isolated and form new species?
There are five isolation processes that prevent two species from interbreeding: ecological, temporal, behavioral, mechanical/chemical and geographical.
What is the difference between inbreeding and interbreeding?
The main difference between inbreeding and interbreeding is that inbreeding is a breeding of genetically similar parents whereas interbreeding is a breeding between two different species the same genus. Inbreeding is mostly used to preserve desirable characteristics in a stock.
How does differential reproduction fit in with natural selection?
If individuals exhibiting variation A of a trait are demonstrated to reach reproductive age more often and produce more offspring than individuals with variation B of the same trait, the differential reproductive success rate allows you to infer that natural selection is at work and that variation A is advantageous—at …
Which of the following would be the most effective management in slowing biodiversity loss?
Environmental Chapter 10 Test
| A | B |
|---|---|
| What is the most effective way to slow the loss of biodiversity? | creating large parks/preserves in biodiversity hotspots |
| In what part of the world are the greatest number of extinctions occurring? | tropical rainforest |
Which of the following statements describes how the development of roads Homes buildings canals and fences most directly threatens wildlife?
Which of the following statements describes how the development of roads, homes, buildings, canals, and fences most directly threatens wildlife? The development destroys wildlife habitats. Which of the following organisms is an exotic species in the United States?
Is the formation of a new species from an existing species Brainly?
formation of new species due to gradual change in the course of evolution from the existing species is known as speciation. Explanation: The new species is formed due to a large amount of change in the genetic sequence of the chromosomes of the individual.
Why do some regions have more species than others?
Hint: Regions that are highly subdivided by geographic barriers such as archipelagos typically have more species than do regions with fewer barriers. The barriers lead to reproductive isolation between populations, initiating allopatric speciation. a. By chance, different species will colonize different islands in a chain. b.
What does population mean in terms of speciation?
population A group of individuals of the same species that live in the same area and interact with one another is a speciation The process that gives rise to new species is called reproductive barrier is anything that prevents successful interbreeding between species.
Why are hybrid zones important to the study of speciation?
Sympatric speciation is _____. Hint: It is due to a radical change in the genome. b. Hybrid zones provide an opportunity to investigate _____. Hint: A hybrid zone allows researchers to see what happens when closely related species come together. Reproductive barriers may be strengthened or weakened, depending on environmental and genetic factors
When does an organism go into allopatric speciation?
Hint: Allopatric speciation occurs when a population of organisms is geographically separated long enough for significant changes to occur. After a period of time, the populations may no longer be able to interbreed. e.
