Question

Natural selection acts existing genetic mutations and does not create new phenotypes in populations. True False QUESTION 3 Common descent with modification implies that all species can trace their ancestory back to a shared ancestral organism True O False QUESTION 4 Evolutionary theory proposes that all living things evolved from a common ancestor. What characteristics would the ancient common ancestor have in common with a human? Choose All That Apply DNA or other genetic material a diploid chromosome number ribosomes that make proteins a cell membrane composed primarily of phospholpds vestigial organs

Explanation / Answer

False. Natural selection causes change in allele frequency and even increases the fitness level of a species which leads to genetic evolution.

True. Phylogenetic tree depicts the evolutionary relationship where closely related species are kept together all linked by their common ancestory.

Going back in time to find a common ancestory would lead to cell membrane made of phospholipid which is the basic element in all the life forms.
