Which term refers to the process by which organisms that are better adapted to their environment survive and breed?
Natural selection is a process where organisms that are better adapted to an environment will survive and reproduce. This means that the advantageous alleles of this variant organism are passed on to offspring. Over many generations, the process of natural selection leads to evolution occurring.
What is the process by which organisms that are better adapted to their environment?
Natural selection is the process by which individuals that have favorable variations and are better adapted to their environment survive and reproduce more successfully than less well adapted individuals do.
Which of the following is the process in which an organism adapts to the environment to survive and produce offspring?
A characteristic that improves an individual’s ability to survive and reproduce in a particular environment. A group of organisms that are closely related and can mate to produce fertile offspring.
What term best demonstrates when an organism is better adapted to the environment that they live in and are more likely to survive and reproduce?
Key terms
| Term | Meaning |
|---|---|
| Common ancestor | An ancestor shared by two or more descendant species |
| Natural selection | Evolutionary mechanism in which individuals that are better suited to their environment survive and reproduce most successfully |
| Variation | Difference between traits in individuals of the same species |
What are the similarities between Darwin and Lamarck?
Darwin and Lamarck’s theories were very different but they were also very similar. They both thought that organisms changed. They thought these changes could be very useful and could help them survive. The changes could then get passed down to the young.
When the environment changes which type of organism is most likely to survive?
According to Charles Darwin’s theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.
Why is Lamarck’s Theory of evolution not accepted?
Lamarck’s theory cannot account for all the observations made about life on Earth. For instance, his theory implies that all organisms would gradually become complex, and simple organisms disappear.
Which is the best definition of an adaptation?
An adaptation is a trait that helps an organism… a) fight better b) overproduce variations c) survive and reproduce d) become larger and stronger 13. An adaptation is a trait that helps an organism… a) fight better b) overproduce variations d) become larger and stronger 14.
Which is true about the evolution of two species?
The evolution of one species into two or more species as a result of different populations becoming reproductively isolated from each other is: 10. The evolution of one species into two or more species as a result of different populations becoming reproductively isolated from each other is: 11.
Who is responsible for the theory of evolution?
The theory of evolution by natural selection was independently developed by: Charles Lyell and Charles Darwin Charles Darwin and Alfred Wallace Erasmus Darwin and Lamarck Charles Lyell and James Hutton 7. The theory of evolution by natural selection was independently developed by:
