Identify two ways that organisms can be compared to provide evidence of evolution from a common ancestor?
- Comparing homologous structures, such as similar bone structures in vertebrate limbs, can provide evidence of evolution from a common ancestor.
- Comparing DNA sequences between different organisms can also reveal genetic similarities that support the theory of evolution from a shared ancestor.

What was the atmosphere in the ordovician period?
The Ordovician period, around 485-443 million years ago, was characterized by a warmer climate with high sea levels and diverse marine life. It was a time of rapid evolution and diversification of marine organisms, including the first appearance of jawless fish. The atmosphere likely had higher levels of carbon dioxide compared to today.
How does the soil composition affect the number and types of organisms and environment can support?
I dont know :d
Was there oxygen in the Paleozoic Cambrian period?
Yes, there was oxygen present during the Paleozoic Cambrian period, but at much lower levels compared to today. Oxygen levels were still increasing during this time due to the evolution of photosynthetic organisms, like algae and early plants.
Tropical rainforests have high what compared to deserts?
Tropical rainforests have high precipitation levels compared to deserts.
How does soil composition affect the number and types of organisms and environment can support?
Soil composition influences the amount of nutrients available for organisms, which in turn affects the types and number of organisms that can thrive in that environment. For instance, soils rich in organic matter can support a greater diversity of organisms compared to nutrient-poor soils. Additionally, soil pH, texture, and moisture content also play a role in determining the types of organisms that can inhabit a particular soil environment.
How do embryo help identify a common ancestor of different organisms?
we compared their bone.
How embryos help identify a common ancestor of different organisms?
we compared their bone.
What are 2 ways that organisms can be compared to provide evidence of evolution from a commo ancestor?
Organisms can be compared through anatomical similarities, where shared structures suggest a common ancestor. They can also be compared through molecular evidence, such as DNA sequences, to reveal genetic relationships and common ancestry.
How does the taxonomic universal ancestor kingdom category present different conclusions about the relations among living than those presented by the previous 5 kingdom system of classification?
The taxonomic universal ancestor kingdom category suggests that all living organisms share a common ancestor, challenging the idea of distinct kingdoms. This concept implies a more interconnected evolution of life forms compared to the five kingdom system, which categorized organisms into distinct groups without considering a universal ancestor. The taxonomic universal ancestor category emphasizes the unity of life and the common evolutionary history of all organisms.
Where are organisms that are closely related located on the tree of life?
Organisms that are closely related are located closer to each other on the tree of life. This means they share a more recent common ancestor compared to organisms that are more distantly related. The branching points on the tree of life represent the evolutionary relationships between different organisms.
Which group of organisms would have the most recent common ancestor the members of a clade corresponding to a genus or the members of a clade corresponding to an order?
The group of organisms within a genus would have the most recent common ancestor compared to a group within an order. This is because a genus represents a subset of species that are more closely related and share a more recent common ancestor than the broader group represented by an order.
What must be true of any organ that is described as vestigial?
A vestigial organ must have lost most or all of its original function in the course of evolution. It is considered nonfunctional or with reduced functionality compared to its evolutionary ancestors.
In a phylogeny or a cladogram how are distantly related organisms?
In a phylogeny or cladogram, distantly related organisms are placed further apart from each other on the branches or nodes of the tree. This indicates that they shared a common ancestor further back in evolutionary history as compared to closely related organisms which are placed closer together on the tree. The distance between branches or nodes reflects the amount of evolutionary divergence that has occurred between the organisms.
What disadvantages do Unicellular organisms have when compared to Multicellular organisms?
Colonies of unicellular organisms can work together.
Are unicellular organisms primitive?
Yew , unicellular organisms are more primitive as compared to multicellular organisms .
What do the structures that result from convergent evolution indicate about organisms?
Structures resulting from convergent evolution indicate that different organisms have independently evolved similar traits in response to similar environmental pressures. This suggests that natural selection favors certain adaptations in specific environments, leading to the development of analogous features in distantly related species.
Are viruses an advanced form of evolution?
Viruses are not considered an advanced form of evolution because they are considered to be simple entities lacking the cellular structure and capability for independent metabolism seen in more complex organisms. They evolve through mutation and natural selection, but they do not exhibit the same level of complexity as organisms that have evolved through millions of years of cellular life.
