Admin What is the term used for traits evolved by organisms to help them survive?
An adaptation is any heritable trait that helps an organism, such as a plant or animal, survive and reproduce in its environment.
How can a human change the traits of an organism?
In artificial selection, humans have the capacity to influence certain characteristics of organisms by selective breeding. One can choose desired parental traits determined by genes, which are then passed on to offspring.
What is the process in which humans breed organisms for certain traits for the needs/wants amusement of humans not the environment?
Artificial selection, also called “selective breeding”, is where humans select for desirable traits in agricultural products or animals, rather than leaving the species to evolve and change gradually without human interference, like in natural selection.
When humans deliberately breed other organisms for certain characteristics?
Artificial selection occurs when humans deliberately breed for certain characteristics.
What are the characteristics of an organism?
A characteristic that improves an individual’s ability to survive and reproduce in a particular environment Adaptation A group of organisms that are closely related and can mate to produce fertile offspring Species The process in which inherited characteristics within a pop change over gens such that new species sometimes arise evolution
How do scientists study the mechanisms of heredity?
The first of these approaches, transmission genetics, involved crossing organisms and studying the offsprings’ traits to develop hypotheses about the mechanisms of inheritance. This work demonstrated that in some organisms at least, heredity seems to follow a few definite and rather simple rules.
What do you mean by natural selection?
The human practice of breeding animals or plants that have certain desired characteristics selective breeding The process by which individuals that are better adapted to their environment survive and reproduce more successfully than less well adapted individuals natural selection
What is the best source of information for studying human evolution?
At one time, data from physical anthropology (including information about skin color, body build, and facial traits) were the only source of information available to scholars interested in tracing human evolutionary history. Today, however, researchers have a wealth of genetic data, including molecular data, to call upon in their work.
