Background

When Charles Darwin first proposed the idea that all new species descend from an ancestor, he performed an
exhaustive amount of research to provide as much evidence as possible. Today, the major pieces of evidence for this
theory can be broken down into the fossil record, embryology, comparative anatomy, and molecular biology.

There are 4 areas of evidence for evolution.

Fossil
Anatomical
Molecular
Embryological
You can remember this as F.A.M.E

The statements you've provided about tigers and lions could relate to different areas of evidence for evolution. Here's how they could be categorized:

  1. Tigers and lions evolved at different times: This could relate to the Fossil evidence, as studying the fossil record can show how species evolved and diverged over time.

  2. Tigers and lions are products of artificial selection: This statement relates more to Anatomical evidence within the context of artificial selection by humans, as selective breeding has altered certain traits in domesticated animals and some wild counterparts.

  3. Tigers and lions are distinct species: This relates to Molecular evidence (such as genetic differences) that can demonstrate how species are defined based on genetic divergence and reproductive isolation.

  4. Tigers and lions adapted to different environments: This relates to Embryological evidence and also anatomical features that show adaptations, as different environments can drive the evolutionary changes in species.

These associations help understand how different lines of evidence contribute to the theory of evolution.

just pick one of the 4 options i gave you pls

Sure! The most relevant option to the evidence for evolution is:

Tigers and lions adapted to different environments.

Fossils

Scientist use fossils to find similarities among ancient organisms and between organisms that live today.

The fossil organisms and modern organisms have identical body sizes.
The fossil organisms and modern organisms have identical body sizes.

The fossil organisms and modern organisms have homologous body structures.
The fossil organisms and modern organisms have homologous body structures.

The fossil organisms are hundreds of thousands of years old, and modern organisms have been around for hundreds of years.
The fossil organisms are hundreds of thousands of years old, and modern organisms have been around for hundreds of years.

The fossil organisms are found in many different rock layers, and modern organisms live in many different habitats.

The statement that best relates to the use of fossils in finding similarities among ancient organisms and modern organisms is:

The fossil organisms and modern organisms have homologous body structures.

Anatomy

There are 3 different types of evidence in Anatomy that help us understand evolutionary relationships between different organisms.

Please match the description with the functions.

Vestigial Structures Analogous structures Homologous structures



Structures like the human tailbone, appendix, and whale pelvis structures.

Evolution has reduced their size because the structures are no longer used.

It is a tiny remnant of a once-larger organ.

Here’s the correct matching of descriptions with the types of anatomical evidence:

  1. Vestigial Structures:

    • Structures like the human tailbone, appendix, and whale pelvis structures.
    • Evolution has reduced their size because the structures are no longer used.
    • It is a tiny remnant of a once-larger organ.

  2. Analogous structures:

    • (These typically describe structures that serve similar functions but are not derived from a common ancestor, such as wings of birds and insects.)

  3. Homologous structures:

    • (These typically describe structures that are similar in form or function due to shared ancestry, such as the forelimbs of humans, whales, and bats.)

Based on your descriptions, all of them relate to Vestigial Structures. If you need explicit matches for the other types (Analogous and Homologous), please clarify.

Molecular similarities provide evidence for the shared ancestry of life. DNA sequences comparisons can show how closely species are related.

Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved.
