All life is an example of evolution. It is the slow change of a species.
The giraffe needed to reach the juicy leaves on the tops of the trees, over a long period of time the trees probably got taller, as did the giraffe
no because animal dose not have to do with giraffe yaeh
Natural selection is where an animal changes over a period of time to adapt to it's environment. For example a giraffe might not have a long enough neck to reach the top leaves on a tree so over many generations the neck becomes longer and longer until it can reach those leaves. This ties in with evolution because the giraffe is evolving to cope with it's environment.
yes
example of an micro-evolution in an organism?
He said that as giraffe stretching out their necks get longer and longer
A giraffe.
To turn giraffe into a singular possessive noun, add an apostrophe and an S, for example: "The giraffe's tongue was very long".
Actually, it was Lamarck who earlier introduced the giraffe as an example for evolution - Lamarckian evolution, to be sure. Lamarck proposed that there was some mechanism by which the short-necked ancestors of giraffes could acquire a change such that their offspring would have necks better suited to their needs. Darwin applied natural selection to the same example mainly because it had already been discussed in such detail.
an example of commensalism in the grasslands is.. a Giraffe and a tree the giraffe is benefiting because he is getting a meal but the tree is harmed or benefiting.
As per the theory of evolution, it took generations for Giraffes to come to present form. Same may be true to any other animal if it want to change like giraffe.
The development of resistance to antibiotics by bacteria is a real world example of evolution.
