Mutation. Giraffes got longer necks then, say, elephants, because some giraffes had slightly longer necks than others. These got more food, so survived, and had long necked children. Eventually they ended up like moodern giraffes

Which term best describes the result of a new species envolving from an existing species?

Speciation is the best term to describe a new species developing from an existing one.


Why do species often form on new islands?

Islands are relatively isolated environments, so there it is less likely that an existing species will move in and outcompete a developing one, and also easier for an existing species to die out since there aren't external populations to replace them. This instability means that the environment can change more quickly, and therefore species must adapt more quickly, compared to the relatively stable environment on the mainland.


Did Charles Darwin make an enormous number of species inhabit earth?

No, he recognised that species evolve into new species.


What is sympatric speciation?

Sympatric speciation is the process by which new species evolve from a single ancestral species in the same geographical area, without physical isolation. It typically involves changes in behavior, diet, or habitat preferences that lead to reproductive isolation between different groups within a population, eventually leading to the formation of distinct species.


How is a new species or group of species represented in the scientists model?

In the scientist's model, a new species or group of species is typically represented by adding new data points, characteristics, or parameters that differentiate it from other existing species. This can involve incorporating genetic, morphological, ecological, or behavioral traits that define the new species within the model. The goal is to accurately depict the unique features and relationships of the newly identified species within the broader scientific framework.

Does biological evolution answer the question of the beginning of species?

Yes, evolutionary theory explains how new species emerge from existing species.

Is necessary for the process of speciation?

Speciation is the process by which new species evolve from existing species. It is necessary for creating and maintaining biodiversity in ecosystems. Without speciation, organisms would not be able to adapt to changing environments and ultimately survive.


What term is used to describe the process for a new species developing from an existing species?

The term used to describe the process for a new species developing from an existing species is "speciation." This process occurs when a population becomes reproductively isolated from the original species, leading to the accumulation of differences over time that eventually result in the formation of a distinct new species.


What do you call the process of change that produces new species from existing species?

evolution


What might happen if one organism disappears from a ecosystem?

if it leaves an environmental niche, then another, already existing, species might take that niche; or a new one might evolve to fill it.

What is the role of time in classifying organisms?

Over time species evolve into new species.


How can you use the word speciation in a sentence?

Specation can be used in many ways.


How does genetic variation create new species over time?

New species evolve from a previous existing species. As challenges arrive in the environment of the old species over many many generations body features are lost and/or gained. Eventually the old species will either eventually die out or change habitats. So basic evolution.
