What is the most important concept in Darwin's theory of evolution by natural selection?
Charles Darwin's theory of natural selection differed from artificial selection in that rather then a conscious agent making the selection of what will be, as in all forms of animal and plant domestication, the selecting agent is the environment itself. Now environment might be thought of as context, and just as a word finds meaning in a given context, example a paragraph, so the forms of organisms are determined by fitting properly their context or environment. All other organisms also form part of that context or environment of a given organism, more directly when there is a predator prey relationship between organisms. This predator prey relationship itself plays a selecting role, as predators tend to weed out the weak or injured in a population of prey organisms. Remember these predators are part of the organisms environmental context.
What is model organism?
Scientists select model organisms to understand that particular life form, and its interactions with other life forms and with the environment. They choose particular organisms as models, because of the hopefully wider applicability of the scientific findings. Scientists think that what they learn from the particular model organism will help them understand other organisms. The basic idea comes from Charles Darwin's On the origin of Species, and The descent of man. According to that idea, all living organisms track back to the same ancestor, or the same ancestral gene pool. In particular, model organisms are selected, to understand human disease. Often, it is considered unethical to use people to sort out possible causes of and treatments for disease. So, for example, causes of and treatments for cancer have been studied through the use of mice in laboratories.
What idea of Darwins based on fossils and the modern organisms he found basically says that genetic changes are inherited by later generations?
decent with modification
What did Darwin assert in his book On The Origin of Species as the mechanism of evolution?
Due to genes and mutations, organisms show variation within a species. Changes in the environment can put a selective pressure on the species - certain mutations may be more beneficial, therefore more individuals with that mutation will exist, as they survive and breed. This process is called Natural Selection.
A group of independent organisms in a particular environment?
population
What is a word for the definition of a group of organisms and their environment?
The word for a group of organisms and their environment is "ecosystem." It refers to all living organisms in a particular area, as well as the physical environment they interact with.
What is known as a group of independent organisms in a particular environment?
population
What is an adaptation and what it used?
Adaptation is when a change in an organisms that makes it suited to a particular environment. It responds to their environment
Many groups species of organisms interacting in a particular environment are an example of a?
Community.
What is it called when the environment affects which organisms will live or die?
That is known as natural selection, a key mechanism in the theory of evolution. Organisms that are better adapted to their environment are more likely to survive and reproduce, passing on their advantageous traits to future generations.
What is the maximum number of organisms of a particular species that can be supported by an environment calles?
population density
What are the unique traits developed by organisms to help them survive thrive and reproduce in their particular environment?
Adaptations.
What is a living factor of an ecosystem?
Is a biological environment consisting of all the organisms living in a particular area.
What are unique traits developed by organisms to help them survive thrive and reproduce in their particular environment.?
Adaptations.
What collects all organisms that live in a particular place together with their nonliving environment?
The ecosystem is a collection of all the organisms that live in a particular place, together with their nonliving environment. Something like mineral soil would be an example of a nonliving component.
What common idea about organisms did these scientists share?
These scientists shared the idea that organisms change over time through the process of evolution. They believed that organisms are adapted to their environment through natural selection, a mechanism proposed by Charles Darwin.
