Taphonomists study
a. undersea life
b. how bone assemblages come to be buried
c. the classification of fossil species
d. plate tectonics

The correct answer is option b.

Explanation:

The study of the procedures by which the organic traces and remains are included in the fossil record is known as taphonomy. It is the subdiscipline of archaeology and paleontology and is primarily concerned with the features and context of fossil remains. Taphonomist refers to an individual who studies taphonomy. Hence, the option that is the study of how bone assemblages come to be buried is studied by a taphonomist.

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.
