Define "Evolution"
It is the change over time
Define "Microevolution"
Small changes accumulate over long period of time till leads to a great change
Define "Macroevolution"
Specification leading to appearance of new species
Define "Fossil"
Remains of a dead organism or its activities.
state one example of derived traits and one of ancestral traits.
Ancestral Traits: Teeth, Tail, Claws
Derived Traits: Feather, Wing, peak
Example of Microevolution
elongation of giraffe's neck.
example of macroevolution
Birds from reptiles
what is the condition for fossilization
hard structure
define "intermediate species"
It has both derived and ancestral trait.
an example of an intermediate species
Archaeopteryx
what is the difference between derived traits and ancestral traits?
Derived traits are newly evolved features that do not appear in the fossils of common ancestors.
Ancestral traits are more primitive features that do appear in ancestral forms.
Anatomically similar structures inherited from a common ancestor are called ...............................
homologous structures.
structures that are the reduced forms of functional structures in other organisms are called ........................
vestigial structures
examples of vestigial structures are ...............................
human wisdom teeth,
the wings of Emus,
and the human tailbone.
an early, pre-birth stage of an organism’s development is called .........................
embryo
The shared features in the embryos of different organisms suggest that .........................................
vertebrates evolved from a common ancestor.
The distribution of plants and animals around the world is studied in the field of .........................
biogeography
what is the importance of the fossil record?
The fossil record is an important source of information for determining the ancestry of organisms and the patterns of evolution.
why islands often have more plant diversity than animal diversity?
because plants are more able to migrate as seeds either by wind or on the backs of birds.
Evolution is also linked to geological forces such as ............................
plate tectonics
the science that study the Common ancestor's traits seen in the complex metabolic molecules that many different organisms share is known as ..........................................
comparative molecular biology
One way to measure how effectively a trait contributes to the reproductive success of an organism is to measure its ...............
fitness
a kind of adaptation that allows the animal to remain unnoticed from a distance.
camouflage
Animals that migrate to find adequate food and suitable temperatures to survive are doing which type of adaptation?
behavioral adaptation
explain antimicrobial resistance
It occurs when bacteria change over time and no longer respond to medicines making infections harder to treat and increasing the risk of disease spread
