In which of the following ways have scientists been able to improve the classification system first devised by linnaeus in the early 1700s?

advances in gene and protein sequencing have led to a better understanding of the evolutionary relationships between species.
developing genetic engineering techniques has allowed us to add entire kingdoms to the original classification system.
improved tracking and mapping technology has provided better information on the geographical ranges of individual species.
knowing the complete sequence of an organism's dna allows us to name it more accurately.

Advances in gene and protein sequencing have led to a better understanding of the evolutionary relationships between species.

Explanation:

From Charles Darwin , we learned that animals do change over time. Therefore, species placement in Linnaean taxonomy has changed as well. As time passed, and knowledge increased, other scientists added to Linnaeus’ original system. Modern Linnaean taxonomy has a hierarchy of seven major taxa, or groupings of organisms.

a tetrad is the foursome during meiosis made by two homologous chromosomes that have each already replicated into a pair of sister chromatids.
