Vidence of common descent<span> of </span>living organisms<span> has been discovered by scientists researching in a variety of disciplines over many decades, demonstrating the </span>common descent<span> of all </span>life on Earth<span> developing from a </span>last universal ancestor<span>. This evidence constructs the theoretical framework on which evolutionary theory rests, demonstrates that </span>evolution<span> does occur, and is able to show the natural processes that led to the emergence of Earth's </span>biodiversity<span>. Additionally, this evidence supports the </span>modern evolutionary synthesis<span>—the current </span>scientific theory<span> that explains how and why life changes over time. Evolutionary biologists document evidence of common descent by developing testable predictions, testing hypotheses, and constructing theories that illustrate and describe its causes.

Answer:
In a fruit fly experiment, grey body, normal winged (homozygous dominant) fruit flies were mated with black body, short winged (homozygous recessive) fruit flies. The F1 dihybrid females were then used in a test cross. If the genes are always linked and no crossing over occurs, what would be the predicted ratio in the F2 generation?
GG x bb = Gb, Gb, Gb and Gb F1 generation
grey body heterozygous offspring 4:0
Gb x Gb= GG, Gb, Gb, and bb F2 generation
3:1 three grey body fly and one black body fly
Explanation:
Answer:
The fossil of the dinosaur looked like it was a combination of two different types of extinct organisms: the meat-eating Tyrannosaurus rex and the Brontosaurus, which was an herbivore. Frankenstein was the name of a monster in a popular story about a scientist who built a monster in a lab. However, this species of dinosaurs evolved naturally. So, calling this species “Frankenstein” wouldn’t be completely accurate.
