Take The Quiz To Learn More About Adaptations Over Time

Evolution refers to the gradual change in species over a long period of time. It is a process driven by genetic variation and natural selection, resulting in the adaptation of organisms to their environment. Through evolution, species can acquire new traits and characteristics, leading to the development of new species over time.

A population that has the least amount of genetic diversity is most likely to go extinct easily because limited genetic diversity reduces the population's ability to adapt to changing environmental conditions. With less genetic variation, there is a higher chance that the population will lack individuals with traits that can survive and reproduce in new or challenging environments. This makes the population more vulnerable to diseases, predators, and other threats, ultimately increasing the risk of extinction.

Charles Darwin proposed the theory of the evolution of species. He is best known for his book "On the Origin of Species" published in 1859, where he presented evidence for natural selection as the mechanism for evolution. Darwin's theory revolutionized the field of biology and had a profound impact on our understanding of the diversity of life on Earth. His work laid the foundation for modern evolutionary biology.

DNA sequencing is the best determinant if two plant species share a recent common ancestor because it allows scientists to compare the genetic material of the two species. DNA sequencing provides a direct and accurate method to identify similarities and differences in the DNA sequences of different organisms. It can reveal genetic variations and mutations that have occurred over time, providing valuable information about the evolutionary relationships between species. Flowering times, morphological features, and stem length can be influenced by various factors and may not necessarily indicate a recent common ancestor.

The correct answer is "Inherited traits." Inherited traits are characteristics or features that are passed down from parents to their offspring through genes. These traits can include physical characteristics, such as eye color or height, as well as behavioral traits, such as learning abilities or instincts. Inherited traits play a crucial role in determining the genetic makeup and overall characteristics of an individual.

Variations refer to the noticeable differences within the members of the same species. These differences can be seen in physical characteristics, behaviors, or genetic traits. Variations are important in the process of evolution as they provide the raw material for natural selection to act upon. They allow individuals within a species to adapt to changing environments and increase their chances of survival and reproduction.

Natural selection is the process by which individuals that are better adapted to their environment have a higher chance of survival and reproduction. This leads to the passing on of beneficial traits to future generations, while individuals with less favorable traits are less likely to survive and reproduce. Over time, this process can result in the evolution of a population as the frequency of advantageous traits increases. Genetic variation is important for natural selection to occur, but it is not the process itself. Therefore, the correct answer is natural selection.

Having more offspring than that could survive is known as overpopulation. This occurs when a population exceeds the carrying capacity of its environment, resulting in limited resources and competition for survival.

Natural selection is the process by which certain traits or characteristics become more common in a population over time. This occurs because individuals with advantageous genetic variations are more likely to survive and reproduce, passing on these beneficial traits to their offspring. Over generations, these helpful genetic variations accumulate, leading to the evolution of the species. The process of natural selection does not involve the killing off of weak members or population explosions, but rather the gradual accumulation of advantageous traits in a population.
