Evolution Answers

15.The following are the pieces of evidence of evolution that may be used to infer the evolutionary relationship between organisms EXCEPT:

a. Comparative Anatomy

c. Molecular Bonds

b. Fossil record

d. Embryology

16.Identify what evidence of evolution is used: vertebrate animals such as humans, chickens and fish have gill slits and tails during their embryonic stage.

a. Fossil record

c. Molecular Biology

b. Comparative Anatomy

d. Embryology

10. How will you differentiate analogous structures from homologous structures as evidence of evolution?

a. Analogous structures indicate common ancestry while homologous structures suggest evolution because of same environmental factors.

b. Analogous structures are structures which indicates that organisms might developed structures with same function as needs arise while homologous structures showed pattern of common descent from different body structures of closely related specie.

c. Both analogous and homologous structures are body structures used by researchers to study the evolutionary development of organisms while vestigial organisms showed different result.

d. B and C

11. What evidence of evolution is portrayed by the unique species on islands which are usually isolated from another mainland?

a. Fossil record

c. Embryology

b. Comparative Anatomy

d. Biogeography

8. This is the study of body structures of organisms to compare and infer evolutionary links. a. Fossil record c. Embryology b. Comparative Anatomy d. Biogeography9. Which among the following best explain the fossil records as an evidence of evolution? a. Recorded events from the past indicates that the Earth was once filled with water. b. Fossils suggest that the Earth is not the same as it is today, for instance there were once a huge massive interconnected land termed as Pangaea. c. Fossils recorded the history of life on Earth and indicates that ancient life forms were different from modern day species. d. Recorded activities of animals from prehistoric times suggest that people came from monkeys.

 6. These body structures indicate that organisms descended from a close common ancestor. a. Analogous structures c. Embryonic structures b. Homologous structures d. Vestigial structures7. Fox and polar bears which are distant relatives both developed white colored fur to adapt to the snowy environment where they habituate. These body structures are identified as: a. Analogous structures c. Embryonic structures b. Homologous structures d. Vestigial structures

There are five individuals in population 1 all with genotype BB. There are 50 individuals in population 2 all with genotype bb. These populations (members of the same species) are widely separated geographically and have similar environmental conditions. What is a likely cause of their genetic variation and why?

I know that animals become extinct. Are "new" animals coming into being? Any examples? Thanks!

There are two alleles in the population of 7500 individuals: the wild-type allele A and the mutation allele a with frequencies of 0.98 and 0.02.

If  population is in Hardy-Weinberg equilibrium, how many individuals would you see with the disease if it was fully recessive?

Evidences of Evolution

if a tiger has stripes in order to blend in with native grasses will that be camouflage or mimicry?

2. What is the movement of genes into and out of a gene pool called?

F. random mating                       H- gene flow

G. nonrandom mating                    J. direct evolution
