Because that is how evolution works. If one species adapts, it can eventually become so different as to be unrecognisable for what it was (given enough time).

What type of evolution is a slow change of one species to another?

Isolation of population and impact of climate change creates speciation. It is the method of slow change of one species to another.

What is co-evolution?

Two species evolving alongside one another, each one adapting according to selection pressures from the other one; a good example of coevolution is between a parasite and host species, and between predator and prey. If a prey species develops a way to better escape a predator species, that predator species, in response, will have to develop a better way to capture the prey.

What is the difference between macro evolution and micro evolution?

The difference is one of scale and scope. This is best explained using a single species and its descendants as an example:Every change that happens to the species up to the point of speciation would be classified as "micro-evolution". But after speciation, divergence would not stop: the two new species would continue to diverge from one another, possibly resulting in yet more branching events, more new species. The scope would increase to include all of those as well. At this scale, we're talking about "macro-evolution". When we zoom in on one of those newly emerged species, we can see that the resulting "macro-evolution" is still being generated by the cumulative effects of "micro-evolution" within each individual population.

What are the definitions of Darwin's theory of evolution?

Darwin only had one theory of evolution, and he defined it in his book On The Origin of Species.

Which of these is an example of macroevelution?

macroevolution is the evolution of one species to another.

What is exhibit parallel and divergent and convergent evolution?

Parallel evolution: two (or more) species or genera that evolve in similar ways over time. Divergent evolution: two or more closely related species or genera that evolve to become quite different from one another. Convergent evolution: two or more unrelated and dissimilar species or genera that evolve to become similar to one another, for example penguins (birds that used to fly), dolphins (mammals that used to walk on land) and fish (animals that were always swimming)

What is mimicry in terms of evolution?

It is when one species copies the behavior or appearance of another, un-related species, to fool predators.

What type of evolution is a slow change of one species to another?

Isolation of population and impact of climate change creates speciation. It is the method of slow change of one species to another.

How does devolution work in biology?

"Devolution" is a misunderstanding. Species evolve over time, as mutations appear and spread and individuals reproduce and die. Evolution tends to produce species that are fairly well adapted to their environment, but they cannot be said to be "better" than any other species. "Devolution" is the idea that species may somehow regress or become more primitive, but any such change is simply another example of regular evolution. Evolution is not graded, so one species cannot be said to be more evolved than another.

What evolution starts with one species and due to different environmental conditions the organisms separate and become more different?

Allopatric speciation.

The process where one species evolves into many different species?


When does one species of organisms become two species?

Through evolution. There are two main kinds of evolution which are gradualism and punctuated equilibrium. In gradualism, natural selection slowly removes unfavorable traits for the environment that the species is living in. After many years the different habitats will result in two species. This same theory is true for punctuated equilibrium except that in p.e. there is a sudden burst of change followed by a dormant state of evolution for the species.

What is the process where one species splits into two different species?

converged evolution

Does sexual reproduction help or hinder the evolution of a species?

Sexual reproduction helps evolution because it allows for changes to take place over generations. Without any reproduction, no evolution would occur because the species only sees change over time and generations, it cannot be seen in one lifetime. Plus, without reproduction, the species will become extinct.

Why is coevolution important?

Because it is one species evolution effecting that of another, this creates an interdependence. It is important to our understanding of biology as well as natural selection.
