Q3 Week 3

Explain the mechanism that produce change in populations from generations to generation (e.g., artificial selection, natural selection, genetic drift, mutation, recombination).

Show patterns of descent with modification from common ancestors to produce the organismal diversity observed today.

Trace the development of evolutionary thought.

EVOLUTION

EVOLUTION

• process

• biological population

• inheritable characteristics

• successive generation of the population

• develops in a long period of time

• adapt to the changes in their environment (purpose)

350 BCE

Species are identical. They tend to remain the same species and can be arranged hierarchically.

Aristotle

​AD 1749

As species change, they migrate to another environment resulting in their distribution

​​George-Louis Leclerc

​1974

Species evolved from one common ancestor

​​Charles Darwin

​DEVELOPMENT OF EVOLUTIONARY THOUGHT

1809

Species evolved from an existing species through environmental forces. Traits can be passed to the next generation.

Jean Baptiste Lamarch

​1830

All changes in the environment are uniform and gradual.

Clarles Lyell

1859

Species evolved from the process of natural selection which cause variations within the population.

Alfred Russel Wallace

​DEVELOPMENT OF EVOLUTIONARY THOUGHT

Jean Baptiste Lamarck

Charles Darwin

​WHO'S WHO?

​VS

THEORY OF ACQUIRED CHARACTERISTIC

​Sometimes called theory of the inheritance of acquired characteristics, or soft inheritance.

Holds that an organism experiencing such a modification can transmit such a character to its offspring.

Theories on Evolution of Organism

Theories on Evolution of Organisms

THEORY OF ACQUIRED CHARACTERISTIC

​Sometimes called theory of the inheritance of acquired characteristics, or soft inheritance.

Holds that an organism experiencing such a modification can transmit such a character to its offspring.

THEORY OF USE AND DISUSE

​Parts of the organism that is regularly use will undergo Hypertrophy and will be developed.

​Sivatherium

Girrafe

THEORY OF NEED

Changes in the environment can arise to NEW NEEDS, required for species' survival.

​Moa

Ostrich

SURVIVAL OF THE FITTEST

Organisms adapt to its environment and survive.

​Darwin

DESCENT WITH MODIFICATION

Species has descended and change over time.

Mammoth

Mechanism of Evolution

​Mechanisms that allow a population, a group of interacting organisms of a single species, to exhibit a change in allele frequency from one generation to the next

NATURAL SELECTION

Process through which populations of living organisms adapt and change.

Finches

​Natural selection is the process of evolution by which organisms adapt to their environment and pass on beneficial traits to their offspring.

ARTIFICIAL SELECTION

Identification of desirable traits by humans perpetuate it to the future generations.

GENE FLOW

introduction of genetic material (by interbreeding) from one population of a species to another

GENETIC DRIFT

The frequency of a trait changes by chance randomly

MUTATION

Genes are damages or changed that alter the DNA sequence

​Anthurium

​Mutated Anthurium

​-Theory of Acquired Characteristics

-Theory of Use and Disuse

-Theory of Need

-Theory on Survival of the Fittest

-Theory on Descent with Modification

-Theory of Evolution by Natural Selection

-Theory of Evolution by Artificial Selection

​-Natural Selection

-Artificial Selection

-Gene Flow

-Genetic Drift

a person who cares for the sick or infirm. specifically : a licensed health-care professional who practices independently or is supervised by a physician, surgeon, or dentist and who is skilled in promoting and maintaining health

​​Nurse

a scientist who studies living organisms. Studying life can mean many different things and be very complex. Biology research can focus on how an organism came to exist, how it is built, how it grows, how it functions, what it does, or where it lives.
