The genetic information in human and chimpanzee DNA shows a high degree of similarity, as humans share about 96-99% of their DNA code with chimpanzees. What is an explanation for this similarity?
They evolved from each other.
They evolved at the same time.
Their evolution is nearly complete
They evolved from a common ancestor.
Green and brown algae share many common features. Both have pigments for trapping sunlight and use photosynthesis for energy. Both store their food as sugars. Both have cell walls and plant-like bodies. However, their DNA suggests that they are not even remotely related to one another. Green algae and brown algae show __________________ evolution, since they look similar, but are not close relatives.
convergent
divergent
homologous
vestigial
Which factor is NOT a strong piece of evidence for evolution?
Fossil records show intermediate forms between modern species.
Most species of bears share more than 99% of their DNA sequence
Many traits of modern birds resemble the fossils of winged dinosaurs.
Lobsters have shells made of chitin, while clams use minerals to make theirs.
Scientists routinely explore whether two different animal species have evolved from a recent common ancestor. _______________ is the LEAST useful technique to help with this determination.
Analysis of strands of DNA
Comparisons of bones and muscles
Comparisons of items eaten for food
Studies of embryos during development
The arm or forelimb of humans, horses, goats, and mice all exhibit the same three bone structures: humerus, ulna, and radius. Which statement BEST explains this common skeletal structure?
The limb bones are similar across these species because they share a common ancestor.
The limb bones are the same across these species because all of them move in a similar way.
The limbs are similar because of the recurring patterns of genetic mutation that are common in the Animal Kingdom.
The limbs are structurally similar due to convergent evolution--different organisms evolving to become structurally similar.
What conclusion would be MOST appropriate about the genetic variation between humans and the three apes as illustrated by the phylogenetic tree?
Genetic variation between all four organisms is non-existent.
The genetic variation between all four organisms is about the same.
The genetic variation between humans and orangutans is the greatest
Humans branched off from the other three animals due to great genetic variations.
The embryonic development of animals suggests an order of relation between humans and other animals; some animals being more closely related to humans than the others. Which of these options arranges the animals in a DESCENDING order of closeness of relation with humans?
I, III, II
II, III, I
III, II, I
II, I, III
In 2010, a new type of life form was found in California's Lake Mono. The microbe found has a variation in the structure of its DNA. DNA is known to consist of nucleotides. In the newly discovered bacteria, it was hypothesized that arsenic is substituted for phosphorus when phosphorus is not present. If true, by substituting arsenic for phosphorous, the microbe would have
a different sugar.
a different nucleotide.
a different phosphate.
a different nitrogen base.
In terms of brain size and overall intelligence, which of these best describes hominid evolution over the last few million years?
brain size and intelligence have increased
brain size and intelligence have decreased
brain size has decreased and intelligence increased
brain size has increased while intelligence has decreased
The fossil beds at the Falls of the Ohio, located between Louisville, Kentucky and Clarksville, Indiana, are world-renowned. There are 212 species of corals known found in these fossil beds. Consider the environmental conditions under which most coral lives. Which scenario MOST LIKELY describes the ancient environment of the Falls?
dry, hot, and near the equator
temperate, northern latitudes, underwater
tropical, near the equator, and underwater
tropical, at the boundary of two tectonic plates
The embryos of a fish, chicken and rabbit all contain a tail and pharyngeal pouches at some point during their early development. Although the fetus of all these species looks different from one another, the similarity between these organisms during their embryological development suggests an evolutionary relationship among all _________________________ species.
avian
invertebrate
mammalian
vertebrate
