Weekly HW 18/Evidence of Evolution

The scientific theory of descent with modification, in which all organisms share a common ancestor; changes in the genetic material of a population over generations.

NGSS.HS-ESS1-2

The branch of embryology that compares and contrasts the developing embryos of various species to show how all animals are related and share a common ancestor.

• Artificial Selection

• Comparative Embryology

• Law of Superposition

• Phylogenetic Tree

NGSS.MS-LS4-3

A feature of an organism that was used by the organism’s ancestors, but no longer serves a purpose for the organism itself.

• Analogous Structure

• Intermediate Fossil

• Vestigial Structure

• Homologous Structure

Tags

NGSS.MS-LS4-2

Due to divergent evolution from a common ancestor, this is a shared characteristic that has a similar anatomy (form) but possibly differing physiologies (functions/ purposes) in different organisms.

• Analogous Structure

• Intermediate Fossil

• Vestigial Structure

• Homologous Structure

NGSS.MS-LS4-2

Due to convergent evolution, this is a shared characteristic that has a similar physiology (function/purpose) but possibly differing anatomies (forms) in different organisms.

• Analogous Structure

• Intermediate Fossil

• Vestigial Structure

• Homologous Structure

Organisms with the same ancestral origin develop into different species with different characteristics over time.

• Natural Selection

• Artificial Selection

• Divergent Evolution

• Convergent Evolution

Tags

NGSS.MS-LS4-2

Organisms with different ancestral origins develop similar characteristics over time due to living in a similar environment.

• Natural Selection

• Artificial Selection

• Divergent Evolution

• Convergent Evolution

Also known as transitional fossils, these are the remains of a species that show the progressive changes from the species’ ancestral form to its most recent descendant.

• Radiometric Dating

• Law of Superposition

• Index Fossil

• Intermediate Fossil

NGSS.MS-LS4-1

NGSS.MS-LS4-2

Any animal or plant remains preserved in the rock record of the Earth that is characteristic of a particular span of geologic time or environment.

• Radiometric Dating

• Law of Superposition
