What is adaptative radiation?
Adaptive radiation is the evolution of a new species in a relatively short period of time. When many species share a single ancestor. burst of diversification of a group of organisms into an array of niches. ADAPTIVE CAUSES: • After mass extinction: - Reptile radiation after P-Tr - Mammal radiation after K-T • Novel environment: - Sweepstakes routes • Evolutionary transition: - Conquest of land, air • Removal of a barrier - Return of more oxygenated conditions • Key Innovation - Examples: Flight, pharyngeal jaws
When two or more species sharing a common ancestor become more different over time is called?
When two or more species sharing a common ancestor become more different over time, it is called divergent evolution. This process occurs as populations adapt to different environments or ecological niches, leading to variations in traits and behaviors. Divergent evolution can result in the formation of new species as these differences accumulate over generations.
What is the process of biological change by which descendants come to differ from their ancestor?
its evolution.check on evolution for more information
How is coevolution similar to divergent evolution?
Coevolution and divergent evolution both involve the process of species evolving in response to changes in their environment or interactions with other species. However, coevolution specifically refers to the reciprocal evolution of two or more species in response to each other, often resulting in a close relationship between the species. Divergent evolution, on the other hand, occurs when two or more related species evolve different traits and adaptations due to different environmental pressures, eventually leading to their divergence from a common ancestor.
Which statement is more accurate to scientist the evolution of a single individual organism or the evolution of a whole species?
Single individuals are naturally selected, but populations ( can be whole species ) evolve. Any mutation happening in the germ line of an individual will die with him. Only his progeny can inherit said mutation and evolve. Evolution is the change in allele frequency over time in a population of organisms.
What does common ancestor mean?
AnswerA common ancestor means that two of more animlas are descended from the same individual. You and your second cousin have a common ancestor in one of your great grandparents; you and your sister have a common ancestor in you mother. AnswerIt means that the species involved evolved from the same ancestor. Contrary to popular belief, evolution does not follow a single path. It is more like a tree branching off in different directions. For example, the pterodactyl and modern birds both have a common ancestor in the archaeopteryx. Whereas each came from a pteranodon, they both evolved into different niches in the environment and thus developed differently.
What is the significance of divergent evolution?
Divergent evolution occurs when two or more species that originated from a common ancestor evolve and accumulate differences over time, resulting in them becoming more dissimilar. This process leads to the formation of new species and contributes to biodiversity by allowing organisms to adapt to different environments and niches.
How does comparing physiological similarities of living species provide evidence of?
Physiological similarities suggest the species evolved from the same ancestor.
What is speciation ?
the formation of species
The relationship between evolutionary time and the similarity of genes in two species?
The longer the evolutionary time between two species, the more dissimilar their genes are likely to be due to accumulating mutations. Conversely, species that share a more recent common ancestor are expected to have more similar genes because they have had less time to diverge through evolution.
A species from which two or more species diverged?
A common ancestor is a species from which two or more descendant species have evolved through the process of speciation. The descendant species can exhibit different traits and characteristics due to adaptation to different environments or selection pressures over time.
How is adaptive radiation different from divergent evolution?
I think it is Puncuated Equilibrium. I am not sure.No Punctuated Evolution is a period of stasis where no changes occur followed by sudden rapid change.It is Divergent
