Darwin’s “Tree of Life” described the evolution of species as a tree that branched out with each branch
creating new species. It is currently believed that not only do species evolve from species branching off to
make new species, the “joining” of species has also been very important for the evolution of species. Please
explain how the “joining of species has been important for evolution. Your explanation need not be long
but should be specific. (6 pts)

Q1: Based on your tree, from which living species did polar
bears evolve from?
Q2: Using branch lengths, how much total evolution (along both
branches) has occurred since these two species diverged from a
common ancestor?
Q3: If this mitochondrial gene evolves at a rate of 0.01
substitutions per nucleotide site per million years, how long ago
did the American and Asiatic black bears diverge from a common
ancestor?
Ailuropoda melanoleuca 0.0494 Helarctos malayanus 0.0494 0.015 Ursus arctos 0.0344 0.015...

11. For this question, refer to FIG. 24.2 (p. 487) "The family tree of the lesser and great apes."This figure shows the derivation of "earlobes". Assume that evolution has not reversed this character state in any of the descendants of this ancestor which evolved earlobes. Given this, what do we know about earlobes? Orangutan Gibbon (14 species in 4 genera) Gorilla Bonobo Chimpanzee Human ebepodeny Robust canine teeth Prosimians: Bushbabies New World Old World and lemurs monkeys...
Can I get a summary of this article name "Evolution Is Happening Faster Than We Thought" By MENNO SCHILTHUIZEN? — A FRIEND recently invited me over to see the blackbird that had taken up residence in a potted plant on her balcony. Serenely incubating eggs in the inner city, this bird had little in common with its shy, reclusive ancestors that nested in Europe’s forests. Early in the 19th century, probably in Germany, blackbirds began settling in cities. By the...

1.Scientific progress requires that we clearly define the question we wish to answer. A clear, sharp definition of a scientific question is often the most difficult step in the process of discovery. Which of the following is the most accurate and complete description of the specific scientific question or problem we will address in this course? a. Humans have no individually unique properties; however, the specific combination of properties we have is not seen in other animals and these properties...

AUGUST 2019 SEPTEMBER 2019 OCTOBER 2019 21. A new disease has just been described with an average incubation period of 21 days, an average latent period of 5 days, and an average communicability period of 6 weeks if not treated.

Could someone please check my answers? 1. A researcher uncovers a fossil in South America that looks quite similar to a species that currently lives in Africa but does not resemble other South American species. The climate and vegetation in the two locations are very different. What is the MOST likely explanation? A. The fossil must have been transported across the ocean during storms. B. The species are probably not closely related due to convergent evolution. C. There was probably...
A cell's genome is its blueprint for life. However, what is the bare minimum number of genes needed to sustain a free-living cell? This is a question that microbiologists at the J. Craig Venter Institute (JCVI) have attempted to answer ever since they sequenced the genomes of several Mycoplasma species in the 1990s. Because Mycoplasma species are parasitic bacteria, their genomes are already reduced in size and hence provide an excellent foundation for creating a "minimal cell." However, little did...
PLEASE SUMMARIZE THE 4 (numbered 1-4) ARTICLES TO 4 SENTENCES FOR EACH NUMBER. THANKS. 1. Medications have to be safe for mothers-to-be and for their unborn children. Before the authorities will approve a new drug, it must be tested in animal trials on pregnant rodents and, as a rule, pregnant rabbits. Scientists in the Department of Biosystems Science and Engineering at ETH Zurich in Basel have now developed a test that allows them to examine a drug's embryotoxicity in cell...
