Friday: Evolution Quiz

What does 'DISRUPTIVE' selection refer to?

• A type of natural selection that favors extreme values of a trait over intermediate values.

• A process where organisms with traits on one end of the spectrum are favored.

• A selection that maintains the status quo and favors average individuals.

• A selection that occurs randomly without any specific pattern.

The distribution of species across geographic space provides strong evidence for evolution by demonstrating how species evolve and adapt to their environments, and how their distributions are shaped by geological events and isolation. E.g. Darwin's finches on the Galapagos Islands, with their diverse beak shapes adapted to different food sources.

• Paleontology

• Biogeography

• Genetic Drift

• Natural Selection

Predation is defined as:

• The act of one organism hunting and consuming another organism.

• The process of photosynthesis in plants.

• The mutual relationship between two species.

• The process of decomposition of organic matter.

Define 'EMBRYOLOGY'.

• The study of plants

• The study of animal behavior

• The study of embryos and their development

• The study of ecosystems

During the Industrial Revolution, soot-covered trees provided camouflage for darker-colored moths, while lighter-colored moths became more visible to predators, leading to a shift towards darker coloration in the population. What type of selection is this?

• disruptive

• sexual

• stabilizing

• directional

Type of evidence for evolution where species may share similar physical features because they share a common ancestor.

• homologous structures

• analogous structures

• vestigial structures

• convergent evolution

________ structures are body parts or behaviors that were once useful to an organism's ancestors but are no longer necessary or have diminished in function in the current species. E.g. human appendix, tailbone.

• Vestigial

• Functional

• Essential

• Primary

In a scientific context, what does 'MOLECULAR' mean?

• Relating to atoms

• Relating to molecules, like DNA

• Relating to cells

• Relating to organisms

What is meant by 'BEHAVIORAL' in biology?

• A type of cell structure

• A type of genetic mutation

• A type of organism's response to stimuli

• A type of ecological interaction

Comparing DNA and protein sequences reveals shared ancestry and evolutionary relationships, demonstrating that all life on Earth is related through a common ancestor. This is ________ evidence.

• genetic drift

• random mutation

• molecular

• natural selection
