Explain how goal of today’s classification system differs from earlier systems

Biology

gladu [14]3 years ago

Classification systems previously were having very different goals than modern classification systems. If we look at old eras, scientists like Aristotle  and Theophrastus  tried to classify organisms on the basis of apparent characteristics, habitat and simple other traits.

Old classification systems had alot of errors and flaws. For example they classified fish and whale in one group because they lived in water, now we know fish is amphibian while whale is mammal.

So we can say that the goal o earlier classification system were just to make groups of organisms on the basis of External features.

Goal of modern classification system:

Modern classification approach was started by Linnaeus. It focuses more on biological delimitation and evolutionary histories than mere external characteristics. It organizes organisms in groups in such a way that grouping reflects their evolutionary relatedness. It is not just specie level but also focuses on sub-specie and population level classification.


Thus modern goal is better in many terms and is more reliable than old classification goals.

Radda [10]

Answer:

This can actually cause a major problem if the number of grasshoppers were to increase out of control. They eat plants and the number of plants,which are the basis of the food chain, could severely decrease which would impact all of the levels operating above this trophic level.

nalin [4]
Answer - C. Reproduction

Reasoning - This was answered before within the community. Here's a reasoning why I chose the answer. - Just like a hydra they are abundant since they can reproduce asexually without having to reproduce with a mate, which means they the ecosystem can eat they and keep the active food chains going.

4. What information would allow you to distinguish between homologous vs. analogous (AKA homoplastic) traits, or to decide wheth
aleksandr82 [10.1K]

Answer:

Homologies - phenotypic and genetic similarities due to shared ancestry

Analogies (homoplastic) - similarities between two species due to convergent evolution instead of descent from a common ancestor with the same trait

In general, organisms that share very similar morphologies or similar DNA sequences are likely to be more closely related than organisms with vastly different structures or sequences. In some cases, however, the morphological divergence between related species can be great and their genetic divergence small (or vice versa).

(plants very different, bc diverged 50 mil years ago)

If internal anatomy, physiology, and reproductive systems are very dissimilar, probably analogous.

The more elements that are similar in two complex structures, the more likely it is that the structures evolved from a common ancestor. If genes in two organisms share many portions of their nucleotide sequences, it is likely that the genes are homologous.:
