How did Darwin explain how organisms change over time?
That trough time, a specie of animal, plant, bacteria can change.When a life form reproduces, one of its"babies" may be different from its parents because of genetic mutation. Sometime, this mutation may give it an advantage over other individuals of its specie. (e.g.: A giraffe has a higher neck and can search food on high trees.) Because of this advantage, the life form that is different (we will call it A) can live longer and has better chances to reproduce. The life form that has not this advantage (we will call it B) will live less longer and will have less chances to reproduce. Because of that, the population of "A" will increase and the population of "B"will decrease. In the end, there will only be "A".
Is Darwin's theory justified?
Yes. There are numerous justifications both for and of Darwin's theory. It beautifully and simply explains the diversity of the tremendously complex biological world in which we find ourselves. Darwin's theory of evolution boils down to just two simple rules. These are that replication is imperfect (variety is introduced into an organism's offspring), and survival is preferential (changing environmental conditions discourage replication of "less fit" individuals). These two rules can be further summarized as: Random mutation plus natural selection. RM+NS. Evolution is the heart surrounding these initials, carved deep into the bark of the tree of life.
Why do you think some African Americans faced less discrimination in the West than they had experienced in the East?
Some African Americans faced less discrimination in the West due to factors like a shortage of labor, availability of land, and a more diverse population. The absence of established social hierarchies and the need for labor in the expanding Western frontier led to more opportunities and less rigid racial attitudes compared to the East.
What percentage of Christians vs Satanists are in the world?
Approximately 31% of the global population identifies as Christian, while the percentage of individuals who identify as Satanists is extremely small and not definitively quantifiable due to the diverse and decentralized nature of Satanism.
What was social drawinism?
Social Darwinism was a 19th-century belief that applied Charles Darwin's theory of natural selection to society, suggesting that the strong and successful should thrive, while the weak and less successful should perish. This ideology justified inequalities and exploitation in society, often used to support discriminatory practices and policies.
Are organisms more or less diverse?
they are less diverse
Are organisms today less diverse or more?
they are less diverse
What is the name of the process that Darwin describes?
The process that Darwin describes is called natural selection. It is the mechanism through which organisms better adapted to their environment tend to survive and reproduce more successfully than those that are less well adapted.
What did Darwin say about natural selection?
Darwin proposed the theory of natural selection, which states that organisms that are better adapted to their environment tend to survive and reproduce at a higher rate than those that are less well adapted. This process leads to the gradual evolution of species over time.
What is the definition of minor phyla?
Minor phyla are taxonomic categories in biology that represent groups of organisms that are less commonly studied or have fewer known species compared to major phyla. They typically include smaller or less diverse groups of organisms within the classification system.
Does the amount of rain that falls in an area determine which organisms live there?
Yes, the amount of rain in an area can greatly influence the types of organisms that can thrive there. Organisms have adapted to specific precipitation levels, so more rain can support more diverse species while less rain may limit the types of organisms able to survive.
How does the soil composition affect the number and types of organisms and environment can support?
I dont know :d
What was central to Darwin's organic evolution?
Central to Darwin's theory of organic evolution is the concept of natural selection, which refers to the process by which organisms better adapted to their environment tend to survive and reproduce more successfully than those less adapted. This process leads to the gradual change and diversification of species over time.
What is the travel time from Australia to India?
Around 12 hours - less if you are based in Darwin
How does having a diverse gene pool help a specie survive?
Species that lack a diverse gene pool are less able to adapt to changes in the environment and are less able to survive diseases.
What process did Darwin's book suggest that organisms evolve through?
These three ideas seem to run together, so it's important that you are able to distinguish among them. The theory that organisms change over time is evolution. The mechanism by which organisms evolve is natural selection. Survival of the fittest explains how natural selection works.Answer = Natural SelectionThe process of natural selection, of course.
How did Malthus theory influence Darwin's theory of evolution?
By writing a book that proposed human suffering and death from starvation because the population of humans went up exponentially but the supply of food goes up arithmetically. Darwin took this idea as an insight. He figured that populations of organisms produced far more progeny then the environment could supply with resources. So a selective process would be put in place. The fitter organisms would survive and reproduce while this much less fit would lose the struggle for existence.
