What question did Charles Darwin ask?
Charles Darwin's main question of inquiry was "How do new species arise and evolve over time?" This led him to develop his theory of natural selection as an explanation for the diversity of life on Earth.
How many types of evolution are there?
well, you get many types like:australopithecus afarensisaustralopithecus africanushomo erectushomo habilishomo sapienhomo sapien sapien
Who theorized that organisms evolve by passing on advantageous traits to their offspring?
Lamarck did. Neodarwinism theorises that species evolve when gene frequencies change, not individual organisms. Larmarkism is true for epigenetic inheritance, favourable and unfavourable characteristics alike.
How does mass extinction affect surviving species?
Extreme radiation events of the organisms that survive the mass extinctions as they evolve to occupy the niches abandoned by the organisms going extinct.
Is unit of evolution species or population?
Population is the unit of evolution. A population is defined as a group of organisms of a particular species that inhabits a particular area. Natural selection acts on traits within that population that are beneficial in the particular area. Another population of the same species may be under different selective pressures (as it is found in a different location), and natural selection may therefore act on different traits within that second population. The two populations, thus, may evolve differently. Therefore, the unit of evolution is the population, not species.
Must population of finches be separated in order to evolve into different species?

When members of a species become separated by geography and loose the ability to interbreed how would scientists classify them?
Scientists would classify these separated members as different species, based on the biological species concept which defines a species as a group of organisms that can interbreed and produce fertile offspring. When geographic isolation prevents interbreeding, the populations may evolve independently and accumulate enough genetic differences to be classified as separate species.
The biological species concept assumes that organisms regularly?
evolve
What is the role of time in classifying organisms?
Over time species evolve into new species.
Why do petals of flower differ in different species?
Different organisms evolve different features because they do not have exactly the same ecological niche, or purely through random chance.
Why do different biomes have different charasteristic organisms?
Different biomes have unique characteristics, such as climate, soil type, and vegetation, that create specific ecological niches. Organisms evolve and adapt to these niches over time, resulting in a diverse array of species in each biome. This specialization allows organisms to thrive in their specific environment, leading to the distinct composition of species in each biome.
How is divergence an evidence of evolution?
Divergence, where organisms evolve different traits over time, is evidence of evolution because it shows that species can change and adapt to new environments. When two populations of the same species diverge and develop distinct traits, it is an indication that they have evolved separately and are on different evolutionary paths. This process highlights the ability of organisms to evolve and adapt to changing conditions, which is a fundamental concept in evolutionary theory.
Do groups or individuals evolve?
Groups of organisms separated from other populations can evolve to form different species over many generations. As bacteria can produce many generations in 24 hours they tend to evolve rapidly. Birds separated by land or water barriers need perhaps one or two hundred years to develop separate characteristics forced on the population by the environment. Individuals can not evolve, only species can evolve by passing on genetic material that enable their offspring to survive long enough to breed. If the environment acts against the offspring with certain characteristics eg a pale moth on a dark background, then those individuals are removed from the gene pool thus affecting the characteristics of the next generation.
When certain organisms evolve together it is considered which type of evolution?
When certain organisms evolve together, it is considered coevolution. This is a process where the evolution of one species is directly influenced by the evolution of another species, often resulting in mutual adaptations to each other.
Why is it necessary for organisms to evolve?
Organisms need to evolve in order to adapt to changes in their environment and improve their chances of survival and reproduction. Evolution allows organisms to develop beneficial traits that help them better compete with other species and overcome challenges in their surroundings. It is a natural process that enables species to gradually change over time in response to evolving conditions.
Why are all organisms different?
Organisms differ because their DNA differs from one species to another, and from one member of each species to another. Organisms differ because according to 'Darwinian science' creatures evolve to fill niches of ecological web. In other words, when species evolve it is to become better adapted to their environment, have a greater aptitude at surviving and then feed on what used to be its predators- who in turn adapt to survive. As this system progresses entropy increases causing an ever increasing diversity of life-forms.
