The finches that Peter and Rosemary Grant chose to study the Finches in the Galapagos because they are hybrid.
Research on Galapagos finches by Peter and Rosemary Grant showed type of natural selection is called what?
Directional Selection

Why did Peter and Rosemary Grant choose to study the Finches in the Galapagos.. What is so special about the finches?
Peter and Rosemary Grant chose to study the Finches in the Galapagos because they were hybrid.
Describe the study conducted by Peter and Rosemary Grant?
They were studying the finches on the Galapagos Island. They were also collaborating to band and measure the finches...
Research on Galapagos finches by Peter and Rosemary Grant showed type of natural selection is called what?
Directional Selection
What evidence did the work of Rosemary and Peter Grant provide that strengthened Darwin's hypothesis about the finches of the Galapagos islands?
The couple spent years observing and documenting environmental conditions of Galapagos finches and how it related to beak structure. They discovered that environmental changes favored certain individuals who in turn, passed those favored traits on to their offspring. This occured more rapidly than previously supposed.
Which 2 scientist demonstrated that natural selection is still at work in the evolution of finches?
Rosemary and Peter Grant.
In Rosemary and Peter Grant's study of the Galapsgos finches what process was encouraged by ecological competition during the dry season?
Directional selection
What environmental variable caused the beaks in Galapagos finches to evolve?
Changes in the weather led to changes in the food supply available. Sometimes there would be hard nuts, and the finches with tough beaks would survive. However, if, on that same island, the weather changed and longer beaks would be advantageous, the tough-beaked finches would die out and slender beaks would dominate. This is proven by the extensive research carried out by Peter and Rosemary Grant from 1973 to the present.
What is a Brief goal of what peter grant study?
Peter Grant studied the finches of the Galapagos Islands to understand how natural selection and adaptive radiation contribute to the evolution of new species. His goal was to investigate how environmental factors drive changes in beak morphology and behavior among different finch populations.
What has the author Peter R Grant written?
Peter R. Grant has written: 'Ecology and Evolution of Darwin's Finches' -- subject(s): Ecology, Evolution, Finches 'Evolution on Islands' 'The evolution of Darwin's finches, mockingbirds and flies' -- subject(s): Finches, Evolution (Biology), Evolution, Flies, Mockingbirds
What did peter rosemary grant study?
they study animals and nature
What did Charle Darwin compare on the bird and what caused the difference?
He didn't do the study of the Galapagos Finches. The people who studied these birds were biologist Peter Grant and Rosemary Grant. They looked at beak size and shape. The finches are commonly called Darwin's finches, however, they really were not studied by him. They used to finches to study Darwin's Theory of Evolution by Natural Selection. In order for NS to occur there must be variation in a population, variations must be heritable, the species must be reproductively successful, and the survival and reproduction of an individual must be nonrandom. The Grants came up with 4 postulates based on the NS model. 1. Is the finch population variable? 2. Is some off the variation among individuals heritable? 3.Do individuals vary in their reproductive success? 4. Are survival and reproduction nonrandom? The overall conclusion that they made was that: when all four of Darwin's postulates are true in a population, the population will evolve; and that evolution an occur over a short period of time.
