Insects and bacteria are said to evolve faster than some more complex animals because they reproduce faster. Simply put the more offspring you can make, the faster they mature and make new offspring with selected genes, then the faster they can evolve.

∙ 11y agoEvery time an organism reproduces there is the chance that a mutation may result. Some of these mutations create an organism which is better suited to survive and reproduce. These "enhancing" mutations are therefore more likely to be passed on thereby "improving" the general gene pool of the species. Bacteria reproduce quickly and therefore have relatively more opportunity to mutate. Because of this fast reproductive rate, evolution can be seen to happen in a matter of weeks for bacteria but takes millennia for humans. Species don't just evolve for the sake of it however. Usually the emergence of a new or modified species is the result of a trigger or catalyst such as a change in environment which allows the better adapted to survive and reproduce while the less adapted die.
...Humans artificially allow the less well adapted to breed which has probably slowed our evolution even further.

Populations of insects and bacteria can evolve quickly because they usually have a short?
I haven't reviewed this in a while but shouldn't it be life spans? The shorter the lifespan, the more generations within a certain time frame there are.
In which organisms could evolution occur most rapidly?
Evolution depends upon genetic variations selected by natural selection each generation, so the species which reproduce the fastest generally evolve the fastest - those would be germs, viruses and other microscopic lifeforms. Cancer cells evolve pretty fast too, unfortunately. Luckily their adaptations are not cumulative, since they cannot reproduce outside of the patients' body and go on evolving for hundreds of years.
Can bacteria grow on hand sanitizer?
my microbiology teacher says it can...she has...and we will in class! alcohol evaporates quickly and the sticky residue that is the base of the sanitizer is actually food for bacteria
The most direct evidence that evolution has occurred comes from what?
Bacteria because they reproduce every 20 minuites which is fast enough so scientist can see them evolve over time. or Viruses, they evolve, that's why we have to constantly change are vacines.
Why can Bacteria are able to produce human proteins?
They reproduce quickly, so they often produce much of the desired protein in a short time.
What Species of bacteria can evolve more quickly than species of mammals because bacteria have?
Most bacteria evolve quickly (in relation to mammalian evolution) because their reproductive cycle is much shorter than "higher" life forms.
Are the bacteria from one colony geneticaly identical?
Bacteria within one colony are generally considered to be genetically identical since they arise from a single bacterial cell that undergoes binary fission to create a population of identical cells. However, mutations can occur that may lead to genetic variation among individuals within the colony over time.
What is the empirical evidence of evolution?
Bacteria, they reproduce so fast you see them evolve.
How do bacteria change and evolve?
how do bavteris change and evolve
Where did plants evolve from?
Bacteria.
Did eukaryotes evolve from bacteria?
No.
Which would evolve faster humans or bacteria?
Bacteria will evolve faster than humans .It is because it has less number of cells and less no. of genes .
Why do leaves rot so quickly in the rainforests?
Leaves rot very quickly in the rainforest because bacteria thrive here. Bacteria are responsible for decomposing organic material in the environment.
Does natural selection deal with only plants?
No, all life evolves. Bacteria evolve, viruses evolve, protists evolve, plants evolve, fungi evolve and animals evolve. Evolution is driven by Natural Selection. So, no. The evolution of all life on Earth is driven by Natural Selection: all bacteria, plants, animals, mammals, fish, insects, biochemical pathways, behaviours et cetera evolve by Natural Selection.
What are clusters of bacteria called?
Bacteria that multiply quickly and have no motility form colonies in a cluster. However, so bacteria that have motility do not form clusters.
When to evolve nidorino?
Oddly, you can evolve it quickly by exposing it to a Moon Stone.
Why are some bacterial diseaes becoming more difficult to treat?
as bacterium are very simple life forms, they are able to evolve very quickly. not really becoming more complex, but changing. this is the reason people catch colds every winter. if the bacteria didn't evolve, we would become immune to it. this means developing a new vaccine every year.some bacteria and viruses evolve slower than others, so some vaccines last years, whilst others last months
