Where did evolution occur?
The only known instance of evolution occurring is here, on Earth. Logic dictates, however, that evolution occurs wherever there is life.
What is evolution and why does it happen?
Evolution is when a species develops and diversifies at the genetic level to better fit it's environment . Evolution is natural , and occurs so species can survive . Scientifically speaking , when the earth was created , there were only single-cell bacteria around . If they hadn't evolved , they probably wouldn't have survived the ice age , etc .
How the gradualism model of evolution differs from the punctuated equilibrium model of evolution?
The gradualism model of evolution states that change occurs gradually over time. On the other hand, the punctuated equilibrium model states that change occurs suddenly or rapidly.
What is it called when the evolution occurs slowly but steadily?
This is the concept of gradualism.
The smallest biological until that can evolve over time is?
the smallest unit of evolution is population.
The smallest unit in which evolution occurs is?
The smallest unit in which evolution occurs is a population.
Does convergent evolution result in speciation?
All evolution that results in increasing genetic divergence between subpopulations may result in speciation. That includes convergent evolution: convergence occurs at the phenotypical level, not at the genetic level.
What are some examples of divergent evolution?
All reproductively isolated populations diverge genetically. Even in cases where convergent evolution occurs, this is only at the behavioural and morphological level. At the molecular and the genetic level, even these instances still diverge at the genetic level.
Which Pokemon does Totodile evolve into?
AnswerTotodile evolves into Croconaw. This evolution occurs around level 18 (although it can be as early as levels 14 or 16 if you are its Original Trainer). Croconaw then evolves into Feraligatr around level 30 (although level 33 is also an acceptable evolution level in different versions).
What is the smallest level on which evolution can occur?
Natural selection acts upon the individual organism, whilst evolution occurs at the population level. The environment selects for organisms best adapted for highest survival and reproductive success. Natural selection requires three key things - variation, inheritable traits, and differential survival/reproduction. Species will produce more offspring than the environment can support(carrying capacity), and the population tends to be fairly stable until resources are limited. A struggle for existence is created, and natural selection ensures that weaker traits die out while stronger traits live on. Organisms show variation in characteristics, and that variation is heritable. Survival depends on inherited traits, and unequal survival/reproduction leads to adaptation and evolution. Therefore, while the individual organism can adapt, the population is what actually evolves.
What is evolution on the smallest scale?
A POPULATION
According to evolution evolution generally occurs when?
Evolution occurs when life forms reproduce with genetic variation of inherited traits, within an environment with a limited carrying capacity (which is basically all environments). In other words, evolution happens where life as we know it exists.
What three items do evolutionists disagree about?
One is that evolution occurs gradually and consistently.The other is that evolution occurs as a result of competition for 'niches'
What is the smallest group of organisms in which evolution can take place?
The smallest group of organisms wherein evolution can take place is a population. This is because all methods of evolution require chromosomes from more than one organism.
Is evolution closely related to DNA?
Yes; changes in DNA are the vehicle by which evolution occurs.
Occurs when species that were similar become increasingly distinct?
Divergent evolution:)
Does evolution occur in individuals or in population?
Evolution occurs in population not in an individual.
