6.2.0.2 Evidence for evolution pt2

Multiple Select

Evidence for evolution comes from studying living and ancient evidence of life. Previously we looked at

• fossils

• anatomical similarities

• animal adaptations

• birth rates

Multiple Choice

based on the given information vestigial means

• no longer used

• useless

• non functional

• unimportant

Examples of low functioning organs: Pelvic bone is used for walking, whales don't walk. The appendix helped digest cellulose, which it no longer does.

Multiple Choice

Embryology is evidence of evolution because it appears embryos

• form only the organism traits

• form traits of different unrelated species that then change into the species being born

• form traits of unrelated species

• appear to form traits of ancestral species which then change into current species traits

Multiple Choice

Features from ancestors show up occasionally in the modern species because they are

• coded for in the DNA

• useful to the organism

• forming a new species

As an infant develops it has features such as gills, which are not useful to a human. The gills later change into something useful with similar function in the embryo.

DNA of individuals is unique. Mapping an entire genome of organisms shows similarities between organisms, DNA coding and organization in the Chromosomes is the same to a certain extent. This example shows the code for the selected genes match in the crime scene and suspect 2, suggesting that individual was at the crime.

Here hemoglobin molecules are analyzed showing which proteins make them up. It can be expected that since proteins are coded for by DNA that those with the same make up have the same DNA coding.

If there are few differences, those organisms' DNA are more similar.

Multiple Choice

According to the Amino Acids coded for in humans and Gorillas, these two organisms are

• genetically similar and therefore have a common ancestor

• genetically similar and therefore have no related ancestors

• no genetic similarities
