Why are lions wolves and whales considered to be social animals?
Because they live in groups and they have a 'pack' hierarchy. They usually travel in groups - and are 'sociable' with each other.
What is a similar structure that indicates species have a common ancestor?
A similar structure that indicates species have a common ancestor is known as a homologous structure. These structures arise from shared evolutionary origins and often serve different functions in different species, such as the forelimbs of mammals, which may serve as wings in bats, flippers in whales, or arms in humans. The presence of homologous structures supports the theory of evolution by demonstrating how different species can diverge from a common ancestor while adapting to various environments.
Homologous structure that is greatly reduced in size?
The pelvic bones in modern whales are an example of a homologous structure that has become greatly reduced in size. These bones are a remnant of the pelvis found in the common ancestor of whales and other mammals, but their size and function have been greatly reduced due to evolution and the adaptation of whales to an aquatic lifestyle.
Which observation BEST supports evidence that two different species share a common ancestor?
The observation of homologous structures, which are anatomical features that are similar in different species due to shared ancestry, best supports evidence that two different species share a common ancestor. For instance, the forelimbs of humans, whales, and bats exhibit similar bone structures despite their different functions, indicating they evolved from a common ancestor. Additionally, genetic similarities and shared embryonic stages further reinforce the idea of common ancestry among diverse species.
What sea animals eat octopus?
No
What are two groups of animals that may share a common ancestor with whales?
hippos
What two groups of animals that may share a common ancestor with whales?
hippos
What difference did scientists discover between today's whales and fossils of their ancestors and how does this show whales and animals with four legs probably descended from a common ancestor?
Scientists have discovered that whales' ancestors had vestigial hind limbs, now absent in modern whales. These vestiges are important evidence of a shared ancestry with four-legged land animals. The presence of these anatomical remnants suggests an evolutionary link between modern whales and four-legged animals from a common ancestor.
What is ambulocetus an ancestor to?
Animals of the genus Ambulocetus are intermediaries between basal mammals and modern whales, and possibly ancestral to modern whales.
Is a hippo an ancestor of the whale?
Yes, hippos and whales share a common ancestor but are not direct ancestors of each other. They both belong to the same group of mammals called Cetartiodactyla. However, whales evolved from a different branch within this group than hippos did.
The DNA sequences of whales and ungulates or hooved animals are very similar. What type of evidence of evolution is this?
The similarity in DNA sequences between whales and ungulates is an example of genetic evidence for evolution, specifically molecular homology. This suggests that both groups share a common ancestor, supporting the theory of evolution by demonstrating how species can diverge from a common lineage over time. Such genetic similarities reflect the evolutionary relationships and the modifications that occur in different environments.
Do bowhead whales migrate in groups?
Yes, groups of a Dozen or more are very common.
What are they 2 groups of whales?
Baleen whales, and toothed whales are two groups of whales.
What organism is the whale most closely related?
Whales are related to the even-toed hoofed mammals. Whales are most closely related to modern hippos, and should share a common ancestor with them.
Whales had an ancient ancestor that lived on?
land
What are some common ocean animals?
dolphins,whales,fish,sharks
why are lions wolves and whales social animals?
Because they live in groups and they have a 'pack' hierarchy. They usually travel in groups - and are 'sociable' with each other.
