Natural selection does not always result in an increase in genetic diversity.

The right answer is True.

If the selection is made on the phenotype, at the individual level, the understanding of the variation of the characters over time and thus of the evolutionary processes requires that one is interested on a larger scale: sets of individuals ( populations).

The genetic diversity resulting from mutations and rearrangements of the genome means that at a given moment, a natural population is not homogenous from a genetic point of view: there are for the most part genes and sequences several alleles, whose frequencies ( allelic frequencies) will vary over time (it could increase, and sometimes decreaqse geneic diversity between the individuals).

using similarities in body symmetry and other anatomical features to assign an organism to a clade involves 1. cladistics based
Jlenok [28]

The process of classifying an organism into a clade by comparing similarities in body symmetry and other morphological traits comprises - 1. body plan-based cladistics cladistics based on body plan, morphology-based phylogeny.

<h3>What is cladistics based on body plan ?</h3>

A method of biological taxonomy that organizes taxa in a branching hierarchy so that all members of a given taxon share the same ancestors and defines taxa uniquely by shared traits not present in ancestral groupings.

  • Cladistics is a method of biological classification in which groups of species (or "clades") are assigned based on theories of most recent shared ancestry.
  • The evolutionary link between recent ancestors and descendants, or the course of evolution, is shown via cladistics. An aid to representing it is a cladogram. Since clades serve as the foundation for phylogenetic trees, cladistics is a component of the phylogeny.
<h3>What is molecular-based phylogeny ?</h3>

Molecule structure is used in molecular phylogeny to shed light on an organism's evolutionary connections.

  • A so-called phylogenetic tree represents the findings of a molecular phylogenetic research. DNA, RNA, and proteins are components of all living things.
  • Molecular phylogenetics creates a phylogenetic tree by drawing conclusions about the evolutionary links that derive from molecular evolution.

<h3>What is Morphology-based phylogeny ?</h3>

Using anatomical features, morphological phylogenetics infers evolutionary trees. Node: A branching point when an ancestral lineage splits into two (or more) daughter lineages in an evolutionary tree.

The ability to discuss the phylogeny of fossil taxa and how they relate to modern taxa is the unquestionable benefit of morphological data. However, their strategy prevents us from addressing the situation of extinct taxa for which there is no way to gather DNA data (i.e., almost all of them).

Pseudopodia

Explanation:

  • Human uses his legs for locomotion and movement similarly in amoeba pseudopodia is used for movement in amoeba and other unicellular organisms.
  • Pseudopodia is a structure in amoeba which is used for movement and locomotion in amoeba and it is also used for engulfing food, amoebic movement is also considered as a protoplasmic movement.
