In the 1700s, _______ Lwho is a Swedish botanist, made a contribution to studying the evolutionary relationship of the different types of organisms. (Nomenclature)

father of taxonomy

A French naturalist proposed that organisms shared ancestors.

He also opposed the idea of the time that the age of Earth is only 6000.

He suggested that the earth was much older.

The idea that "all living things were descended from a common ancestor" (grandfather of Charles Darwin)

In 1809, he proposed the idea that "all organisms evolved toward perfection and complexity" in which he further explained that species evolved into different features.

He also proposed that organisms tend to change due to the condition of the environment and behaviour to change, resulting the use and disuse of a structure.

was coined (synonym phrase) by Herbert Spencer.

huge diversity of plants and animals in the tropics region including the fossil records. Their ideas were presented to a group of scientists in London.

In 1859, Darwin published his thoughts.about evolution and natural selection in On the Origin of Species.

It was as popular as it was controversial.

According to Stephen Nowicki, "there are four main principles to the theory of natural selection that can result in biodiversity:

suitable environment for survival and reproduction

heritable differences from difference in genetic traits of the parent

have enough food resources and shelter to reproduce and survive

potential to adapt themselves to fast changing type of environment

This refers to the scientific study of embryos and their development.

Fish, birds, mammals, and reptiles have similarities based on the result of shared common ancestry.

It refers to the physical structures of organisms that have the same evolutionary origin and positions.

As they progress, the animals developed differently in response to the function of their appendages (arms and leg).

It refers to the structure of animals which is gradually disappearing.

A structure of an organism that have few or no function but is clearly homologous to the structure.

This is another evidence in organisms have the basic heredity units for all life which consist of similar nucleotides and proteins

These are remains of plants and animals over the past 3.5 billion years.

It may be in the form of bones, shells, leaves, and foot prints of animals.

To determine the age of the fossilized organisms, they used ____ dating like the K-Ar isotope.

can be found through the help of paleontologists.

is the study of fossils in an effort to try and understand the evolution and interactions between organisms and their environment.

In the 18th century, Paleontology was established as a science following the works of ____ who worked on comparative anatomy. However, it was in the 19th century when the field developed quickly.

is the scientific study of human artifacts through analysis and recovery of these material cultures.

as a field of study can be categorized as social science and a branch of the humanities.

the transfer of alleles from the former population to another population

this is a change in allele frequencies that affect an organism to be eliminated

____ occurs in the DNA sequence, which causes a nucleotide base to be inserted, deleted or substituted

Mating is an important effect on evolution population. Female animals have a greater chance to select their mates.

happens when males display unique traits that attract the females.

Happens when there is competition among males. The one who win will mate with the female.

These are the processes by which new species arise and existing species lose and cease to exist. This is the integral part of evolution in which many organisms are affected all the time.

refers to the formation of two or more new species from one existing species

three types of speciation

occurs when there is an imbalance of gene flow between two populations due due to physical barrier

happens if there is an overlapping range of the two diverging species within a region or locality

reproductive isolation occurs within an area by mutation

happens when there's a limited gene flow of the two species that may diverge from a single species following hybridization

divergence of non-hybridized species would result in speciation

geographical barrier

partial spatial isolation

genetic polymorphism

isolation of a population at the periphery

This happens when members of different population of species can no longer mate successfully or do not interbreed.

This occurs when population have different courtship rituals or behaviors involved in reproduction.

This occurs when there are changes or disruption of the ecosystem or by means of physical barriers such as mountain rise, continent drifts or when population of species migrate.

it refers to a strong mating of two different species which later develops into a new species

the term the term "ploidy" means multiplying the number of chromosomes of the species

changes in the number of chromosomes are common in plants which are habit on land

this is the basic functional unit of ecology which includes organisms, populations and communities.

the abiotic component (temperature and light)and biotic component (organisms) are very much interrelated

all life forms on earth are important in the

it refers to the different species within a region or community

the number of species in a region or community possesses genetic variation and distribution

many species live on land than in the sea

it refers to the variation of genes within species

it covers distinct populations of the same species

it refers to the different biomes, which is called the world's major communities, which are characterized by adaptations or organisms in a particular environment.
