About 3 million years ago, the Isthmus of Panama (a narrow strip of land connecting North and South America) formed, dividing marine organisms into Pacific and Caribbean populations. Researchers have examined species of snapping shrimp on both sides of the isthmus. Based on the morphological species concept, there appeared to be seven pairs of species, with one species of each pair in the Pacific and the other in the Caribbean. The different species pairs live at somewhat different depths in the ocean. Using mitochondrial DNA sequences, the researchers estimated phylogenies and found that each of these species pairs, separated by the isthmus were indeed each other's closest relatives. The researchers investigated mating in the lab and found that many species pairs were not very interested in courting with each other, and any that did mate almost never produced fertile offspring. Use the species concepts to explain how the sister populations on opposite sides of the isthmus are true…
The ancestor of cats was presumably homozygous for wild type at all of the described genes.
What was the phenotype of this ancestral cat at each of these loci?
1)Dark grey with black mackerel stripes
2)Light grey female with dark grey mackerel stripes
3)Light brown male with chocolate tips
4)Black female with large white patches
5)Cream male with small white patches and orange mackerel stripes
6)A uniformly colored black cat
The tiny frog Paedophryne amauensis was discovered by researchers purposefully searching for the source of an unusual sound, but sometimes similarity between two species can lead scientists to accidental discoveries. A previously unknown species of wild cat was inadvertently discovered by researchers who were sequencing the DNA of a house cat–sized South American wild cat called the tigrina. The DNA analysis revealed that many alleles found in the supposed tigrinas living in northeastern Brazil are not shared with other tigrinas. This finding suggested that the northeastern cats do not interbreed with other tigrinas and are therefore a different species. What prevents the two species from interbreeding?

- A group of researchers are trying to determine the relationship between various groups of organisms. The researchers analyze the amino acid sequence of the protein cytochrome c in various groups of organisms. Once they sequence cytochrome c in all organisms, they determine the number of amino acid substitutions in each group. The results can be seen in the graph below, which plots the data with respect to the time since the divergence of the members of paired groups from a common ancestor. A B mammals and reptiles с Number of Amino Acid Substitutions (per 100 amino acids) in Cytochrome, c D 60- 50+ 40+ 30- 20+ 10+ 0 0 O birds and reptiles A graph showing when various groups of organisms diverged from a common ancestor Based on the graph above, can you conclude which of the following organisms are most distantly related? 200 400 600 800 1,000 Time Since Divergence from a Common Ancestor (millions of years) fish and land vertebrates mammals and reptiles birds and mammals insects and…arrow_forwardSuppose species 1, 2, and 3 are endemic to a group of islands (such as the Galápagos) and are all descended from species 4 on the mainland (which will serve as an outgroup; its large population size means that no new mutations have become fixed in its population in the time since the islands were colonized). You sequence a gene and find ten nucleotide sites that differ among the four species (among many other loci that do not vary). The nucleotide bases at these sites are: Species 1: GCTGATGAGT Species 2: ATCAATGAGT Species 3: GTTGCAACGT Species 4: GTCAATGACA Estimate the phylogeny of these taxa by plotting the changes on each of the three possible unrooted trees and determining which tree requires the fewest evolutionary changes.arrow_forwardA fossil believed to be the most recent common ancestor between housecats and lions is radio-dated to about 11 million years ago (mya). An analysis of a neutral section of mitochondrial DNA in both species finds 15 DNA base pair differences between the two cats today. Meanwhile, an analysis of housecats and pumas shows 4 DNA base pair differences between them, which are believed to have diverged around 3 mya. Using this data, what is the best estimate of the time since divergence of housecats and lynx, which have 11 DNA base pair differences in this mitochondrial DNA region? 5 mya O6 mya O 7 mya O8 mya 9 myaarrow_forward
- Which of the following best explains the number of similarities between the amino acid sequences of the Drosophila Hedgehog protein and the Chicken Indian Hedgehog protein? O A. The Drosophila hedgehog gene evolved from hedgehogs, which are distantly related to birds. O B. Both genes evolved from a gene present in the last common ancestor of Drosphila and chickens, and the number of differences reflects the amount of time that has elapsed during the evolution of these two lineages. a During the evolution of Drosophila and chickens, a hedgehog like gene arose independently in each lineage, then the gene that arose in chickens diversified. A These genes are unrelated, and the fact that they are similar is only because the proteins need to have similar biochemical properties. They are unrelated because chickens don't have segments and Drosophila larvae don't have limb buds.arrow_forwardHumans carry a variety of non-functional genetic sequences, called processed pseudogenes, in their DNA. we can estimate how long ago these sequences first appeared in the genomes of our ancestors. In humans, processed pseudogenes include the three options below which would be the least widespread among other primate species a. alpha-enolase psi1 (11 million years old) b. AS PSI 7 (16 million years old) c. CALM II PSI3 (36 million years old)arrow_forwardThe platypus is one of a very small number of mammals that are venomous. Researchers compared the substances in the platypus venom to that of venomous reptiles. They found that the venom in platypus was derived from a protein called defensin, while that in many reptiles was based on a protein called crotamine. The protein structure of these molecules is remarkably similar, though they are controlled by unrelated genes in each taxa. Both molecules originated as non-toxic antimicrobial compounds. Part A: Venom in both platypus and reptiles is an example of: A. Homologous traits B. Analogous traits C. Adaptive radiation D. Genetic drift Part B: A trait matrix for the amniotes is below.

- 50. The polar bear (Ursus arctos maritimus) is thought to have evolved from the Siberian brown bear (Ursus arctos beringianus), in the Kamchatka peninsula of Russia during the Riss glacial period, about 150,000 years ago, when advancing glaciers isolated a subpopulation of brown bears in Kamchatka, preventing them from interbreeding with the ancestral brown bear population in mainland Asia. As the Kamchatka bears adapted to a tundra habitat (evolving into polar bears), they became distinct from the ancestral brown bears, who remained adapted to a boreal forest habitat. With the boundary between tundra and boreal forest persisting to the present, isolating modern brown bears from polar bears, the descendant species (tundra-dwelling polar bears) probably originated from the ancestral species (boreal forest-dwelling brown bears) by means of which of the following pre-zygotic mechanisms? A. speciation by F2 hybrid breakdown B. allopatric speciation by means of vicariance C. speciation by…arrow_forwardYou are studying two populations of pika. You find that the population inhabit in talus (broken rocks) are greyish. Another population live in coniferous forests have black fur. When individuals from each population are brought together in the lab, they produce offspring whose appearance is intermediate between the two parents. The offspring can breed and reproduce successfully with each other or pika of either parent population. You sequence three genes, Pigmentosa, Sparkly, and Zippy. For each of the three genes, the two populations differ from each other at a few nucleotides (<1%). Why is it hard to determine if these two pika populations belong to the same species or are two different species? In your answer/argument, refer to at least two pieces of evidence from the above scenario. Note, we are NOT asking you to determine if these are the same species or not.arrow_forwardA.
