Darwin
What term refers to the process by which individuals that are better adapted to their environment are more likely to survive and reproduce?
What is natural selection?
A biology teacher asks students to give examples of genetic variations that support the idea that changes in a population’s environment affect genetic variation. Would changes in genetics in human populations be a very supportive example?
What is no
A bird that preys on moths is introduced to the habitat with moths and trees like the ones shown below. What will most likely happen to the population of moths in this habitat?
What is the population of light moths will increase due to a selective pressure?
What is the theory where evidence supports similarities in body structures, patterns of early development and fossils.
What is the theory of evolution?
Giraffes having increasingly longer necks over time is a classic example of what?
What is natural selection?
A Punnett square shows you all the ways in which ____ can combine.
What is alleles?
A student has written a paper about a deer population that was separated when a canyon developed between members of the group. In her paper, she showed that the two groups adapted differently and can no longer interbreed. What would be the best title for her paper?
What is speciation by geographical isolation?
Scientists combine evidence from fossils, body structures, early development, DNA, and protein structures to discover what?
What are evolutionary relationships?
Consider two male oryx that are physically fighting each other. What main point of Charles Darwin is being depicted?
What is organisms within a population compete with each other to survive?
What is the term for an organisms' physical appearance?
What is phenotype?
Jezelyn needs to create a project that shows geographic isolation in action and decides to make a video. If she created a video that shows a large river that has penguin populations on both sides, what type of speciation would her project show?
What is speciation by geographical isolation?
Which type of selection leads to increased phenotypic and genetic variation?
What is disruptive selection?
What did Darwin infer from his observations of organisms in South America and the Galápagos Islands?
What is a small number of different plant and animal species had come to the Galápagos Islands from the mainland?
What is the term for the sum of all genetic traits in a population’s individuals at a given time?
What is a gene pool?
A student has written a paper about a deer population that was separated when a canyon developed between members of the group. In her paper, she showed that the two groups adapted differently and can no longer interbreed. What would be the best title for her paper?
What is geographical isolation?
Henry was studying two populations of the same species of lizards. One population lived on an island and the other lived on the mainland. Both populations were affected by a hurricane that hit the island and the mainland with equal force. A year later, Henry was testing the gene frequency and saw a decrease in genetic variation in the island species, but not in the mainland species. What is a conclusion he might have reached?
What is how genetic drift greatly affects small populations, but large populations can recover.
Charles Darwin hypothesized that some individuals would be better equipped for survival than others, and that those that were less equipped would not survive. Darwin formulated this hypothesis based on the work of which scholar?
Who is Thomas Malthus, who studied population growth?
A population of chimpanzees was separated when the forest that they lived in had a section cut down and a town was built. After a long period of time, the chimpanzees came back into contact but were incapable of breeding. Which of the following best describes the process that occurred?
What is speciation?
Babies with very low or very high birth weight are less likely to survive. A graph that shows the percentage of babies born at different weights shows what type of selection if the average of their weights are favored?
What is stabilizing selection?
Bird droppings that contain seeds from a different location is an example of what?
What is gene flow?
