Are spiders and octopuses related through common ancestry?

Updated: 4/27/2024

Not closely: spiders are arachnids (a type of chelicerat), octopuses are cephalopods (a type of mollusk).

However it is believed that all living things do have an ultimate common ancestor, no matter how much they have diverged from each other.

Spiders and octopuses belong to different phyla: spiders are arachnids (part of the arthropod phylum) and octopuses are cephalopods (part of the mollusk phylum). While both groups are invertebrates, they are not closely related through common ancestry.

How is evolutionary classification different from Linnaeus's system of classification?

Evolutionary classification groups organisms based on their shared evolutionary history and genetic relationships, while Linnaeus's system of classification is based on observable physical features and similarities. Evolutionary classification reflects the understanding that all organisms are related through common ancestry, while Linnaeus's system focuses on organizing organisms into hierarchical categories based on shared physical characteristics.

Why does Darwin use a tree as a model for the evolution of animals?

Darwin used a tree as a model for the evolution of animals to represent the divergence of species from a common ancestor. Just as branches on a tree diverge from a common trunk, species evolve and diverge from a common ancestor through natural selection and adaptation. This visual representation helped illustrate the concept of common ancestry and the branching of species over time.

How can I get the 1897 Russian census to locate family records?

The 1897 Russian census records are available online through various genealogy websites and archives. You can try searching on platforms like FamilySearch, MyHeritage, or Ancestry to locate your family records from the 1897 census. Additionally, you may visit local archives or historical societies in Russia that may hold physical copies of the census records.

A database is made up of related?

tables that store structured data in rows and columns. Each table represents a specific entity or concept, and relationships between tables are established through keys that link them together. This allows for efficient storage, retrieval, and manipulation of data within the database.

Why are all the people on earth members of the same biological species?

All human beings share a common ancestor and have evolved over time through a process of natural selection. This has led to the development of one species, Homo sapiens, which includes all individuals living on Earth today. Despite variations in traits like skin color or hair texture, humans retain the ability to interbreed and produce fertile offspring, indicating shared ancestry and genetic compatibility.
