Tues 12.10 Cladogram Assessment

Front

What is a cladogram?

Back

A cladogram is a diagram that shows the evolutionary relationships among various biological species based on similarities and differences in their physical or genetic characteristics.

Front

What does it mean if two organisms have similar DNA sequences?

Back

It suggests that the organisms are closely related and may have a common ancestor.

Front

What type of evidence is used to determine evolutionary relationships?

Back

Evidence can be molecular (DNA), anatomical (body structures), embryological (developmental stages), or fossil records.

Front

What is the significance of homologous structures?

Back

Homologous structures indicate that different species have evolved from a common ancestor, as they share similar anatomical features.

Front

What is natural selection?

Back

Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring.

Front

How does predation affect population dynamics?

Back

Predation can lead to changes in population sizes, often favoring the survival of certain traits over others, such as coloration in beetles.

Front

What is the role of embryological evidence in evolution?

Back

Embryological evidence shows similarities in the early developmental stages of different organisms, suggesting common ancestry.

Front

What does a greater number of differences in DNA base pairs indicate?

Back

It indicates that the organisms are more distantly related.

Front

What is the importance of fossil evidence in understanding evolution?

Back

Fossil evidence provides a historical record of past life forms and their evolutionary changes over time.

Front

What are analogous structures?

Back

Analogous structures are body parts in different species that have similar functions but do not share a common evolutionary origin.
