What kind of features can convergent evolution lead to?

What are the two stages of human evolution?
1) The Life Cycle-- tracing the development of a baby from the fetus stage to old-age adulthood. 2) The genetic "evolution" of human natural selection that gives rises to the different "races" of people, which is really variations (with the emphasis on phenotypical variations) within human kind. There is nothing beyond this, as ameobas to man type of macro-evolution is not only a philosophical story, it is also not well supported scientifically. This belief is, therefore largely assumption and less scientific.
Why are missing link fossils a powerful evidence for Creation and not for evolution?
Some people who reject the biblical account of Creation think that living things went though gradual changes (biological evolution) from one kind to another. In order to support their beliefs, they find fossils that, when lined up, seem to show a continuous change from simpler organisms to a much larger and more complex one. But fossils for the most part do not show gradual changes from one kind to another. They are clearly one kind or another not something in between. For example; fossils of mice exist and fossils of bats exist, but no fossils of half-winged, mouse like creatures have been found.
What does evolve means?
It means came into being over time by the processes of evolution, as set out by Charles Darwin.
Can Evolution proceed even if there is no genetic variability?
Not biological evolution in the standard sense. No variation, genetic variability, and there is nothing for natural selection to select from.

What kind of behavior changes as a result of environmental changes in Bangladesh?

Did planets have evolution?
Planets form, and they undergo changes as they age. This process of change might be termed 'geological evolution', but this should not be confused with biological evolution, which is an entirely different kind of process.
What rate does evolution occur?
there are two different rates that evolution could occur at. the first kind is gradual, which is small changes over time. the other kind is fast and it occurs when there is a big change the environment.
Why do many vertebrates have the kind of bones arranged a little differently?
They are the result of slight changes in the genetic information that produces them.Due basically to their common ancestry. Evolution just builds on the past and does not innovate when it can tinker, So, the closer the ancestry is the closer the skeletal arrangement will be.
A kind of change in matter that produces a new substance?
Nuclear and Chemical changes result in new substances.
How may changes to genes that is mutation result in harmful beneficial or neutral effects to the organism?
Mutations are random changes so there is no way to predict what kind of effect they will have.
An example for evolution?
My favourite example of evolution is the development of multicellular organisms (this has also been observed). A kind of eukaryotic cell once started to bind to its fellow cells in order to make it more difficult for predators to kill them. This is an example of evolution as a result of predation, a selective agent.
When heat and presure are applied to a rock what kind of rock results?
Exposure to intense heat and/or pressure can result in changes to a rock's mineralogy, crystal structure, and mineral alignment. Such changes can create a metamorphic rock.
How much natural selection leads to evolution?
All natural selection results in evolution. But natural selection is not necessarily the only mechanism leading to evolution. There are processes at work on a molecular level, such as intragenomic conflict-type processes, that also result in differential reproductive success, but aren't exactly related to the kind of processes Darwin first described.
