What else can I help you with?
When the internal strucure of two species are very similar what can be inferred about both species?
They evolved from a common ancestor.
What supports the scientific theory that all species share a common ancestor?
Evolution.
What term is used to describe structures that come from a common ancestor?
A taxon of closely related species that share a recent common ancestor is a genus.
Species that share a common ancestors have?
Species that share a common ancestor have similarities in their genetic makeup, anatomy, and evolutionary history. These shared traits provide evidence of their relatedness and the branching points in their evolutionary tree.
How are the organisms on a branching tree diagram grouped?
Branching tree diagrams (or cladograms) attempt to show the ancestral relationships between species. The groupings indicate relatedness - closely grouped organisms will be more closely related (sharing a more recent common ancestor) than organisms which descend from earlier divisions, which will be further away on the cladogram.
What does it mean when two species share a common ancestor?
An ancestor.
Are lions related to the hyenas?
They share a common, very distant ancestor.
When the internal strucure of two species are very similar what can be inferred about both species?
They evolved from a common ancestor.
What is a common ancestor?
a common ancestor is a species that multiple species share as the species they descended froma person born or that has lived before you and the word common means the same SO ....... its when you have the same descendant or person who lived before you or an ancestor that's the same
What does it mean if species are said to have common ancestor?
If species are said to have a common ancestor, it means they are believed to have descended from a single, shared ancestor species in the past. This indicates that despite differences observed in the species today, they share a genetic and evolutionary heritage that links them back to a common origin.
What supports the scientific theory that all species share a common ancestor?
Evolution.
Why do related species share homologous traits?
Related species have inherited homologous traits from a common ancestor.
Two species are said to be related if they share the?
Two species are said to be related if they share a common ancestor. This means that they have evolved from a common predecessor and have similarities in their genetic makeup and physical characteristics. The degree of relatedness is determined by how recently they diverged from this common ancestor.
Do seals and humans share a common ancestor?
yes they do in facts share a common ancestor.
Do plants and animals share a common ancestor?
Yes, plants and animals share a common ancestor.
What does a branch point in a cladogram represent?
The branch point in a cladogram represents a specific ancestor that is separated into two or more species. For example a leopard and a house cat share a common ancestor. A similar example is that a wolf shares a common ancestor with the leopard's and house cat's ancestor but the wolf's ancestor lived longer than the leopard's and house cat's ancestor. Scientists use something called cladistics to determine the one common ancestor that multiple species have in common.
What term is used to describe structures that come from a common ancestor?
A taxon of closely related species that share a recent common ancestor is a genus.
