2. \"the present is the key to the past.\" this statement rephrases the (1 point). principle of cross-cutting relationships. law of gravity. principle of uniformitarianism. principle of original horizontality. 3. why would a worm stand a poor chance of being fossilized? (1 point). worms did not exist in the geologic past.. worms have been rare during the geologic past.. worms have no hard parts.. all of the above

1. principle of uniformitarianism, 2. worms have no hard parts

The principle of uniformitarianism suggests that the geological processes occurring in the past were in the same manner and with the same intensity that as they occur in the present. Therefore, the phrase "The present is the key to the past" rephrases the principle of uniformitarianism.

A worm cannot be fossilized because it does not possess hard parts like bones, shells, teeth as other organisms exhibit. They have tube like body with soft tissues, which gets completely decomposed by microbes after death.  

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.
