How does the fossil record provide evidence of common ancestry?
Age and structure of fossils can suggest that multiple species were descended from a common ancestor.
The fossils found in the deepest levels of rock depict the youngest organisms of that species.
Common ancestry can be proven by measuring the decay of the carbon 14 isotope in organic matter.
Descent from a common ancestor is suggested by the comparison of rock samples found with fossils.

14) whenever diploid populations are in hardy-weinberg equilibrium at a particular locus a) the allele's frequency should not change from one generation to the next, but its representation in homozygous and heterozygous genotypes may change. b) natural selection, gene flow, and genetic drift are acting equally to change an allele's frequency. c) this means that, at this locus, two alleles are present in equal proportions. d) the population itself is not evolving, but individuals within the population may be evolving.
