Hardware and software.
Here's the full list of system requirements for Continuity:
https://support.apple.com/HT204689
(except it doesn't mention AirDrop.)
Explanations:
Software:
OS X 10.10 Yosemite introduced the original set of Continuity features:
Handoff, AirDrop (to/from iOS), Instant Hotspot, iPhone Cellular Calls
and SMS/MMS Forwarding.
macOS 10.12 Sierra (or later) added Universal Clipboard, Auto Unlock
with Apple Watch.
On the iOS side, AirDrop was in iOS 7; Handoff in iOS 8; Instant
Hotspot, iPhone Cellular Calls, SMS/MMS forwarding in iOS 8.1; Universal
Clipboard in iOS 10. (watchOS 3 for Auto Unlock.)
Hardware:
Handoff, AirDrop (to/from iOS), Instant Hotspot and Universal Clipboard
require the Mac to be a 2012 or later model, because they need Bluetooth
4.0. iOS hardware also needs to be mid 2012 or later: minimums are
iPhone 5, iPad 4th gen, iPad mini, iPad Pro, iPod Touch 5th gen.
Auto Unlock with an Apple Watch requires a 2013 or later Mac model,
because it needs a special feature of the 802.11ac Wi-Fi hardware (to
determine the physical distance to the Apple Watch via a high resolution
measurement of the round trip time for a Wi-Fi signal).
iPhone Cellular Calls and SMS/MMS Forwarding have no special hardware
requirements, because they use Wi-Fi or Internet respectively, no
Bluetooth involved. For example, these will work as far back as an
iPhone 4s (running iOS 8.1 or later) and any Mac (running Yosemite or
later).
Note that the Mac had another variant of AirDrop introduced in Mac OS X
10.7 Lion. It is supported on all Late 2010 or newer models, plus some
models as far back as Late 2008. The Mac-only and iOS-compatible methods
are quite different: the Mac-only version uses peer-to-peer Wi-Fi, while
the iOS-compatible one uses both Bluetooth 4.0 and peer-to-peer Wi-Fi.
Yosemite and later default to the iOS-compatible version, with a "Search
for an Older Mac" button to switch to the older Mac-only version.

Mystery solved, good.
