Question
Chapter 26.3, Problem 2CC
Summary Introduction
To find: Accuracy of parsimonious tree and its occurrences.
Introduction:
Parsimony is the science depicting simple scientific notion with proper evidence. Here, tree building makes other aspects equal while best hypothesis needs minute evolutionary fluctuation.

The most parsimonious tree of evolutionary relationshipscan be inaccurate. How can this occur?
n which situation would it make sense to use the phylogenetic species concept?
When you are not able to collect data about how individuals in your study use their habitat, but you are able to collect reproductive data
When you are able to collect data about how individuals in your study use their habitat, but you are unable to determine if they interbreed
When you only have genetic data about each organism in your study
When working with fossils from extinct organisms
Phylogenetic trees are constructed based on parsimony the idea that the simplest answer is the misy likely. Explain why a parsimonious tree is a likely but not the only possible answer when depicting evolutionary relationships.

- A phylogenetic tree is different from a cladogram in that ... Group of answer choices A: it shows that all species are not related to a common ancestor, but each has a distinct archetype. B: it represents the time scale of evolution, including where extinct species fit in. C: it uses an outgroup to compare a small group of species that exhibit similar traits D: it is not based on genetic or morphological evidence.arrow_forwardWhat are the two key facets of the Darwinian Theory of evolution?
