What is anatomically similar structure inherited from a common ancestor?
The pentadactyl limb structure, found in mammals, birds, reptiles, and amphibians, is inherited from a common ancestor. Despite modifications for different functions, such as wings in birds and flippers in whales, the underlying bone structure remains similar.
What are 2 examples of indirect evidence supporting evolution?
Fossil record: The transition of species over time, as documented through fossils, provides indirect evidence of evolution and common ancestry. Comparative anatomy: Similarities in the anatomical structures of different species, such as the pentadactyl limb in vertebrates, suggest a shared evolutionary history.
What is an example of common descent?
An example of common descent is the similarities in anatomical structures of different species, such as the pentadactyl limb structure (having five fingers or toes) found in mammals, birds, reptiles, and amphibians. This shared trait suggests that these species have a common ancestor and have evolved from a common lineage.
How do you use homologous structure in a sentence?
A homologous structure is an example of an organ or bone that appears in different animals, underlining anatomical commonalities demonstrating descent from a common ancestor.
What are structures that develop from the same embryonic tissues but have different mature forms?
Homologous structures develop from the same embryonic tissue but mature into different forms in different species. An example is the pentadactyl limb in vertebrates, where the same bones form the wings of a bat, flippers of a whale, and arms of a human.
Do dogs have pentadactyl?
Yes they do
What is the root word pentadactyl?
The root word of pterodactyl is tera. This root word means trillion.
Do humans have pentadactyl limbs?
yes
Do dogs have pentadactyl limbs?
yes they do
Do bats have pentadactyl limbs?
Bats do have pentadactyl limbs. Its wing is the forelimb version of the pentadactyl limb. In the bat, the forelimbs have turned into wings for flying by great elongation of four digits, while the hook-like first digit remains free for hanging from trees.
Do bats have two arms and two legs?
Yes, bats do have four limbs,pentadactyl limbs.
How is homo-logy in the pentadactyl limb evidence for adaptive radiation?
Homology in the pentadactyl limb, where different species share a common limb structure despite having different functions, is evidence for adaptive radiation because it suggests that a common ancestor with this limb structure diversified into various species to adapt to different environments or ecological niches. The conservation of the pentadactyl limb's basic structure implies that these species diverged from a shared ancestor through adaptive changes to exploit different habitats and resources.
What is the root meaning of pentadactyl?
Having five digits to the hand or foot., Having five appendages resembling fingers or toes.
What is a pentadactyl appendage?
I will focus on the on the pentadactyl FORELIMB (arm). It is the limb that is common in vertebrates (e.g. humans, birds, dogs, whales, bats ALL HAVE ONE!). It supports the theory of evolution by strengthening the idea of divergent evolution and the idea of a common ancestor by showing that different environmental conditions and different selective pressures can result in vastly different characteristics being selected in common species. Each limb consists of: * humerus - upper arm * radius - forearm * ulna - forearm * carpals - wrist * metacarpals - palm * phalanges - fingers/digits Due to the fact that various organisms have a pentadactyl limb, it is difficult to give a definite answer to what it looks like because it varies from organism to organism. Think of as your own arm as an example of a pentadactyl limb to get a clearer image in your head: * from your shoulder to your elbow is the humerus * from the elbow to the wrist are the ulna and radius * your wrist is the carpal * your palm is the metacarpal * your fingers are the phalanges
What is the root word of pentadactyl?
Dactyl is actually a word fragment from the Old Greek 'dactylos' - two-jointed (three segment) finger, first (English) attested 1498, its origin predates written Greek by (at least) centuries
