Слайд 2Ontogenesis
Ontogeny is the origination and development of an organism

(both physical and psychological). usually from the time of fertilization

of the egg to adult. The term can also be used to refer to the study of the entirety of an organism's lifespan.

Слайд 5 ONTOGENETIC BEHAVIOR

Each organism has

a unique life history that contributes to its behavior. Ontogenetic behavior is due

to events that occur over the lifetime of an individual. Ontogenetic history builds on species history to determine when, where, and what kind of behavior will occur at a given moment.

ONTOGENETIC BEHAVIOREach organism has a unique life history that contributes to

Слайд 6Medical Definition of Phylogeny

The evolutionary history of a kind of

organism.
The evolution of a genetically related group of organisms

as distinguished from the development of the individual organism. — called also phylogenesis. — compare ontogeny.

Слайд 9Relationship between phylogenesis and ontogenesis
The pharyngeal (branchial) region represents

a classic example where the relationship between ontogenesis and phylogenesis

has been demonstrated.
It is a region where the development of gills during ontogenesis of all chordates has been recapitulated.

Relationship between phylogenesis and ontogenesis The pharyngeal (branchial) region represents a classic example where the relationship between

Слайд 12How does a phylogenetic tree work?

Rules

The root of

the tree represents the ancestral lineage, and the

tips of the branches represent the descendants of that ancestor. ... When a lineage splits (speciation), it is represented as branching on a phylogeny. When a speciation event occurs, a single ancestral lineage gives rise to two or more daughter lineages.

How does a phylogenetic tree work? Rules The root of the tree represents the ancestral lineage,

Слайд 17Phylogenesis of the chord avian skin covering -
Its epidermis is

both keratinized and lipogenic, and the skin as a whole acts as a sebaceous

secretory organ. The skin is covered by feathers over most of the body, but many birds show colored bare skin or integumentary outgrowths on the head and neck.
