What does it mean for species to have an evolutionary relationship?
If two organisms share an evolutionary relationship, that means that they have a common ancestor on the evolutionary tree. The more recently the shared common ancestor lived, the more closely related the two present organisms are, evolutionarily.
What does similar structures in embryos mean?
the species come from a common ancestor
I have a cousin who is a common ancestor and he has his first cousin the girl I love her so much Does it mean that she is also related to me too just like where cousins?
Only if you share a common ancestor
Why is the theme of evolution consider to be the core theme of biology by biologists?
I assume you mean evolutionary theory. Because it explains the complexity of all life and also explains all life's two main components; the unity and diversity of life.
If your grandfather's brother married a woman who has a sister whose daughter is your age does it mean you are related to the daughter?
No, you do not share a common ancestor.
What if your aunt and uncle are not together anymore does that mean his daughters cousin's are no longer our cousin's?
They were never really your cousins. You don't share a common ancestor.
What does common ancestor mean?
AnswerA common ancestor means that two of more animlas are descended from the same individual. You and your second cousin have a common ancestor in one of your great grandparents; you and your sister have a common ancestor in you mother. AnswerIt means that the species involved evolved from the same ancestor. Contrary to popular belief, evolution does not follow a single path. It is more like a tree branching off in different directions. For example, the pterodactyl and modern birds both have a common ancestor in the archaeopteryx. Whereas each came from a pteranodon, they both evolved into different niches in the environment and thus developed differently.
Did human beings really used to be monkeys?
Sometimes people say, "Scientist claim we used to be monkeys!" But that's not quite right. Scientists say we share a common ancestor with today's apes.Just as you and your cousin have grandparents in common, so you and those monkeys you see at the zoo have a common ancestor. But that common ancestor lived millions of years ago!Monkeys, apes and humans are all primates. And all three share certain common characteristics - like ten fingers and ten toes, flattish faces and large brains. But there are obvious differences, too - and those differences are due to evolution.Scientists say that our closest living relatives are chimpanzees, but that doesn't mean that we used to bechimpanzees. We have been evolving seperately for about the last six million years. From a common primate ancestor, two unique species have developed - chimpanzees and homo sapiens(that's us).
Are arthropods a small group?
Yes, by definition all arthropods are taxonomically related in the sense that they share membership in the same phylum (Arthropoda); although this does not necessarily mean they share a common ancestor.
What is at the root of a phylogenetic tree?
Do you mean ' the universal common ancestor? '
How are nucleotide sequences used to put organisms in evolutionary order?
When comparing nucleotide sequences in organisms, we find that the organisms that have less differences in their nucleotide sequences are closer related in the evolutionary tree. By this we mean that the common ancestor from which these two organisms evolved is more modern than the ancestor they might share with an organism that shows more difference in the DNA sequencing. Example: the chimps and humans share a common ancestor that is relatively modern because the difference in their nucleotide sequences is just about 1% but the differences between the nucleotide sequence of humans and fish shows lots of differences which shows their common ancestor y much older than the one with chimps.
What does it mean to have descent from a common ancestor?
Having descent from a common ancestor means that multiple individuals or groups share a lineage tracing back to a single individual or population in the past. This shared ancestry is typically determined through genetic or genealogical evidence, and it indicates a common genetic heritage among the descendants. It implies that these individuals or groups are related, albeit distantly, and have inherited certain genetic traits or characteristics from their common ancestor.
