POB2 Lecture 10-13 Review

When using maximum parsimony to infer a phylogeny, we choose and avoid the trees that

Rock flow is caused by a cycle of cooling and heating via convection cells

The X axis of a phylogenetic Tree can represent

What is disruptive selection (select all that apply)?

What is an example of postzygotic barrier

The earliest signs of life in rocks were from Microbial mats and stromatolites

Groups that include the last common ancestor and most of its descendants are known as

If a group has phenotypic variation,heritable,and the variation is correlated to the rate of reproduction,the results

Sister groups are

The first prokaryotes were risen during the Archaen Era

Rock Flow

Speciation that results when an ancestral population is split into two isolated populations by new mountain ranges

Evidence for late Precambrian snowball earth include ancient ice deposits

The origin of the Earth and Solar System occured in which era

Alu elements make up more than 10% of the typical human genome because

Which statement about prezygotic isolation is false?

Single Eukaryotic cells arose estimately around the

If a phylogeny is represented as C((D, B,)(A,E)), what can infer about taxon C and Taxon A ?

A drift is an uniform random sampling selection ( biased random sampling)

According to the Breeder’s Equation, the response to selection is the selection differential times the

The conditions for natural selection to occur are

The theory behind Ernst Haeckel's Phylogenetic tree is most relevant to towards how we view phylogenic trees today

If we measure dN/dS ratio = 0.4 for a protein-coding gene two butterfly species, what can we infer about how that gene?

Prezygotic Isolation Include

The first sight of visible life (I.e. animals , humansm colonization of land) occured in the

The moon is somewhat chemically similar to the earth

Genetic exchange among bacteria that involves obtaining DNA from the environment via engulfment is

Orthologs are

What is the parentheses equation of the tree on the left

The results from the famous 1950s Stanley Miller "chemical soup" experiment concluded that:

The Red Queen phenomenon involves

Based on the phylogentic tree what is the sistergroup to Oppusoms

Photosynthetic prokaryotes are responsible for banded iron formations because they

The rate of beneficial mutations are higher than deleterious mutations

Polyphyletic groups are species grouped via ancestors

Under the neutral theory of molecular evolution, the rate of evolution of a DNA sequence that doesn’t affect fitness is

Stable Isotope Geochemistry involves

Populations can become allopatric actively through dispersal events

Which is the earliest subunit in the Phanerozoic Era?
