|Name two creatures that macroevolutionists claim are intermediate links and why they are not really intermediate links.||Archeopteryx and the Australopithecus Afarensis, because they are just a ape and a bird.|
What was the main idea that Sir Charles Lyell’s work have to Darwin?
What was the main idea that Sir Charles Lyell’s work gave to Darwin? LYELL came up with the idea that the PRESENT IS THE KEY TO THE PAST. HE THOUGHT THAT THE ENTIRE GEOLOGICAL GEOLOGICAL COLUMN could be explained by referring to the same processes that we see happening today.
Which protein would you expect to be the most similar to a protein with the following subset of amino acids?
Which protein would you expect to be the most similar to protein with the following subset of amino acids? The protein in c. is most similar.
Where did Darwin do most of the work?
Where did darwin do most of the work which led to his hypothesis of evolution? He did it in the Galapagos Islands on the HMS Beagle ship.
What is the Cambrian Explosion Why is this a problem for evolution quizlet?
Why is the Cambrian explosion a problem for evolution? The sequence of intermediates that evolution says should exist between simple Precambrian organisms and complex Cambrian organisms does not exist. Mutations are most often harmful not helpful to organisms.
What is the principal means by which oxygen is taken from the air?
What is the principal means by which oxygen is taken from the air? oxygen is taken from the air principally by respiration and oxygen is restored principally by photosynthesis.
Which amino acid is a good buffer at physiological pH?
The only amino acids with R-groups that have buffering capacity in the physiological pH range are histidine (imidazole; pK′=6.0) and cysteine (sulfhydryl; pK′=8.3).
What makes an amino acid a good buffer?
An amino acid can act as a buffer because it can react with added acids and bases to keep the pH nearly constant. ( NH2 ), it can act as both an acid and a base. In very acidic media, the NH2 group is in the protonated form, and in very basic media, the COOH group is in the deprotonated form.
Why was the Cambrian explosion an important event in the evolution of life on the earth quizlet?
The Cambrian Period marks an important point in the history of life on Earth; it is the time when most of the major groups of animals first appear in the fossil record. This event is sometimes called the “Cambrian Explosion,” because of the relatively short time over which this diversity of forms appears.
How does punctuated equilibrium explain the absence of intermediate forms?
Fossils seem to appear suddenly throughout history. Punctuated equilibrium tries to explain these fossil ‘gaps’ or the absence of intermediate forms, by stating that they exist for very short periods of time when speciation occurs intensely in an isolated population.
What are the criticisms of punctuated equilibrium theory?
The criticism of punctuated equilibrium focuses on the possibility that fossil records may simply be incomplete. Intermediate forms may be found in regions where fossils are abundant and well-preserved. In addition, critics point to the fact that there is no evidence that an external homogenizing influence keeps interbreeding populations in stasis.
Are there intermediate links in the fossil record?
The fossil record: Against; There are no clear intermediate links in the fossil record. Structural homology: Against; The similar structures are not a result of inheritance from a common ancestor, because the similar structures are determined by quite different genes.
Where can I find support for punctuated equilibrium?
Support for punctuated equilibrium is seen in fossil records. The impact of reproductive isolation has been observed by biologists, systematists, and taxonomists across the world. Given the fact that this is a theory of evolution, its predictions cannot be directly tested.
