Evolution pt 2 (Embryology & Fossil Record)

Front

What is comparative anatomy?

Back

Comparative anatomy is the study of the similarities and differences in the anatomy of different species, which provides evidence of common ancestry.

Front

What is the geological time scale?

Back

The geological time scale is a system that organizes Earth's history into different time intervals, including Eons, Eras, Periods, Epochs, and Ages.

Front

Why is quick burial important for fossilization?

Back

Quick burial protects remains from environmental factors and scavengers, increasing the chances of fossilization.

Front

What are the different types of fossils?

Back

The main types of fossils include body fossils, cast fossils, and trace fossils. 'Mask' is not a recognized type of fossil.

Front

What are vestigial structures?

Back

Vestigial structures are body parts that have lost their original function through evolution, such as the human appendix.

Front

What is embryology in the context of evolution?

Back

Embryology is the study of the development of embryos, which can show similarities between different species, indicating common ancestry.

Front

What are homologous structures?

Back

Homologous structures are anatomical features in different species that share a common ancestry, even if they have different functions.

Front

What are analogous structures?

Back

Analogous structures are body parts in different species that serve similar functions but do not share a common ancestry.

Front

What is natural selection?

Back

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

Front

What is a fossil?

Back

A fossil is the preserved remains or traces of ancient organisms, providing evidence of past life on Earth.
