EVIDENCES

These can be observed in places where one can examine actual changes in a population of organisms within a particular period.

Direct evidence

Indirect evidence also known as?

Circumstantial evidence

refers to information that implies a

fact or event without directly proving it. This

type of evidence relies on an inference to

connect it to a conclusion of fact.

Indirect evidence

the remains or impressions of

plants or animals preserved in rocks or

sediments.

fossils

They are used to compare ancient species

with their modern counterparts.

fossil records

It refers to a person's lineage or the lineage of any living organism. It is essentially the line of descent traced continuously from an ancestor.

ancestry

refers to the evolutionary

history and relationships among different

species or groups of organisms.

phylogeny

It's essentially a "family tree" for species,

showing how they are related through

common ancestry.

phylogeny

Fossilized species that share traits with

present day descendants

transitional fossils

fascinating and meticulous

process in paleontology where

scientists piece together the

remains of ancient organisms to

create a more complete picture

of what they looked like and how

they lived.

fossil reconstruction

These are body parts that share a

common structure and origin but may

have different functions in different

animals.

homologous structure

pentadactyl limb is an example of

homologous structure

It consists of the bones making

up the appendages of tetrapod

vertebrates and often refers to

the ‘arm’, although can also

refer to the ‘leg’ as well.

pentadactyl limb

Structures that are found in different species that generally have the same function but are anatomically different.

Analogous structure

These are reduced forms of formerly

functional structures.

vestigal structure

It is the study of how embryos of different

species develop and compare to one

another.

comparative embryology

early stage of

development in multicellular

organisms.

embryo

the study of the difference and

similarities in biological or physiological

processes among organisms.

comparative biochemistry

It involves the study of genes,

proteins, and enzymes in comparing

various organisms.
