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.
Why did modern ape not evolve?
When things evolve, the whole species doesn't change. Theres one member of the species that is born different (slightly) and if it does well then it passes on its genes. The old species doesn't go away unless for some reason it stops doing well and dies out (by "doing well" I mean finding enough food and reproducing.) So to answer your question in a more straight forward way, they DID evolve because they aren't the same as prehistoric apes. They just didn't evolve in the same way we did.
Did Charles Darwin make an enormous number of species inhabit earth?
No, he recognised that species evolve into new species.
Must population of finches be separated in order to evolve into different species?
bye
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.
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.
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.
Explain why it is incorrect to say that individual organisms evolve?
It is not correct to say that individuals evolved because it is not possible for an individual to change drastically over their own timelife. Species have the faculty to evolve as a whole not as individual organisms.
What does it mean when organisms evolve?
they change in ways or mutate in to a different form.
Do organisms evolve slowly over time and can two different organisms have a common ancestor?
Yes they evolve slowly over time and a panda and raccoon have common ancestors.
What event occured that allowed single celled organisms to evolve into more complex organisms at the end of the precambrian time?
the ozone layer began to develop shielding earth from ultraviolet rays, this was hypothesized that these changes allowed species of single celled organisms to evolve into more complexed organisms
