If two organisms have similar traits in DNA what do they have in common?
If two organisms have similar traits in their DNA, they likely share a common ancestor. This genetic similarity suggests that their evolutionary paths diverged more recently compared to organisms with greater genetic differences. Additionally, these traits may indicate shared functions or adaptations that have been preserved through evolution. Such similarities can be used to classify species and understand their evolutionary relationships.
What model is sometimes used to identify a group's derived traits?
The cladistic model is often used to identify a group's derived traits, known as synapomorphies. This approach classifies organisms based on shared characteristics that are derived from a common ancestor, allowing researchers to construct phylogenetic trees that illustrate evolutionary relationships. By focusing on these derived traits, cladistics helps in understanding the evolutionary pathways and diversification of species.
Why can species with short life cycles be used to directly observe evolution?
Because a single human can analyse several generations of the species - which can lead to evolutionary traits forming.
What was the species concept most used in linnaeus?
Linnaeus primarily used the morphological species concept, which defines species based on their physical characteristics and shared similarities in appearance. He classified organisms primarily based on their observable traits such as size, shape, and color.
Do biologists use pedigrees to create a cladogram?
No, biologists use pedigrees to trace the inheritance of traits within a family or population. Cladograms are used to show the evolutionary relationships and common ancestry among different species or groups of organisms.
Why is it difficult to clearly define the term species?
Defining the term "species" is challenging because it encompasses a diverse range of organisms and reproductive behaviors. Various criteria, such as morphological, genetic, ecological, and behavioral traits, can be used to classify species, leading to differing interpretations. Additionally, phenomena like hybridization and asexual reproduction blur the lines between species, complicating the application of rigid definitions. This complexity has led to the development of multiple species concepts, each with its own strengths and limitations.
What is the main purpose of a cladogram?
A cladogram is a diagram used in biology to show evolutionary relationships between different species. It helps scientists understand how different species are related based on shared characteristics and can be used to study patterns of descent and common ancestry.

What is the Chinese zodiac chart What is it used for?
The Chinese zodiac is based on birth year rather than time of year and is used for defining personality traits. Unlike the traditional zodiac, it is not used for predictions or horoscopes.

A group of organisms that share similar characteristics?
Class, Phylum, Family... there's a bunch of answeres to that one. *~* Kingdom, Phylum, Class, Order, Fammily, Genus, Species These are categories used to classify all living things on the earth. Kingdom is the top, going down to species. Specific traits that are sahred among a group of organisism can be unique to any one fo these groups from the Kingdom to the species.

What species do earthworms belong in?
There are many, many species of earthworm. The Common Earthworm, which is the species I think most are used to seeing belongs to the species Lumbricus terrestris.
