Adaptation has a different meaning in the context of evolution than in everyday use. Is the following statement correct or incorrect in the scientific sense? "When an individual fiddler crab moves from water onto land, it changes its posture to a more upright stance to adapt to the increased weight of its body on land."

The statement is correct in scientific sense.

Explanation:

Adaptation refers to the traits or characteristics posses by living organisms which enable the organisms to be better fitted to survive, and reproduce in it's environment.

Adaptation is an evolutionary process I.e. features are evolved by the organisms to be better suited in it's environment.

From the statement, an individual crab develop characteristics that enable it to change its position which enable it upright stance to further adapt to life in land.

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.
