A heritable trait is one that
Is determined at least in part by genes past from parents to offspring
What does it mean that organisms have a nearly universal genetic code?
A specific DNA sequence and codes, the same information in one species as it would in nearly any other
A biologist observed that a particular plant species is found in a forest, but not in a nearby meadow she hypothesizes that the plants could grow in the meadow, but are not found there because their seats have yet to land in the meadow, which of the following would be the most appropriate way to scientifically evaluate this hypothesis
Scattering seeds in several areas of the meadow and observing whether they start to grow
An adaptation is _____
A trait that gives an organism, a reproductive advantage in the current environment
Charles Darwin______
Propose natural selection as the mechanism of evolution
From his observations of organisms in the Galápagos Islands Darwin reason that_____
Organisms had adapted to new environments, giving rise to new species
Which of the following observations led to Darwin‘s major inferences
-although organisms can produce huge numbers of offspring, many of these offspring do not survive
-Members of the population Vary in their heritable traits
Which one of the following researchers developed a theory of evolution that was very similar to Charles Darwin
Wallace
The diagram is reminiscent of Darwin sketch showing the branching of evolution. The horizontal axis of the diagram is a timeline that extends from 100,000 years go to the present. The vertical access represents nothing in particular. What does each fork represent in the diagram?
The most recent common ancestor of the subsequent branches
Darwin use the phrase descent with modification to explain which of the following ideas
The unity and diversity of life arose from adaptive successes of the past ancestors
Which of the following statements best describes evolution
Population has changed genetically from one generation to the next
Currently two living elephant species X and Y Our classified in the genus loxodonta And the third species Z is placed in the genius Elphas. The switch of the following Statements would be accurate
Species X and Y share a greater number of homologies with each other than either does with species Z
Currently two of the living elephant species X and Y Are placed in the genus loxodonta And the third surviving species Z is placed in the genus elphas Assuming this classification reflects evolutionary relatedness, which of the following is the most accurate evolutionary tree
The tree where X and Y are in the same branch and Z is isolated on its own
What is the meaning of Darwin’s expression descent with modification?
Decent with Modification refers to evolutionary change over time
